General Appearance

Catocala Sara, n. sp.Expanse 3.10 inches. A form in size and general appearance resembling C. Aspasia, Streck., but having much darker colored fore wings, besides other points of difference. Primaries blackish gray from the base to the t. a. line, along the posterior margin to the subterminal line, and from this in a broad band to the costa, the inner part of this band running along the inner side of the reniform. This color is formed of a black or brownish black ground, sprinkled with white scales. This leaves a pale space between the stigmata from the median vein to the costa, and the whole end of the wing beyond the dark space spoken of. T. a. line indistinct, of the ground color, but with less white scales; t. p. line distinct anteriorly, one large and one small tooth opposite the reniform. Subterminal space scarcely tinged with brown, the subterminal line white with a sprinkling of black scales. Orbicular indistinct, black with a few white scales, reniform with a few white scales and an annulus of gray, Terminal space gray. Secondaries rosy red, the median band very much as in the form Walshii, not reaching the inner margin, a little constricted opposite the disc, beyond this a little enlarged, after which it narrows to less than half tlie costal width. Terminal line like Walshii, with an internal excavation before the anal angle that reaches half through the band.

The species collected are four in number, three of which were previously known to occur on the shore of the Island, viz. :— Harpagifer bispinis, Choenichthys rhinoceratus , and Notothenia coriiceps . The fourth is a Ray, apparently undescribed, which may he characterised thus :— Raja eatonii. Allied to B. smithii . Snout of moderate length, the anterior margins meeting at a right angle; the width of the inter-orbital space is two-sevenths of the distance of the eye from the end of the snout. The anterior profile, from the snout to the angle of the pectoral fin, is slightly emarginate, the outer pectoral angle being rounded. The greater part of the upper surface of the body is smooth, minute spines are distributed between the eyes, and in a narrow stripe along the margins of the body; a broad band of minute spines along the median line of the back and the upper surface of the tail ; a single larger recurved spine in the middle of the back ; a series of nine or ten rather small spines placed at a considerable distance from each other along the median line of the tail; no spines on the side of the tail. Lower parts smooth. Upper lip fringed on the side; teeth pointed, conical, in about 30 series in the upper jaw. Male with a patch of claw-like spines on each pectoral fin. Brownish black above, with indistinct round whitish spots ; whitish below, with some irregular brownish-black spots; lower part of the tail brownish-black.

Cucullia Hartmanni, n sp.Expanse 1.75 inches, length of body .75 inch. General color of fore wings pale gray, so suffused in places with dark gray as to give the wings a moderately dark gray cast, but not so dark as C. intermedia, Spey. Lines black, basal half line only indicated on the costa. T. a line double; the inner part almost imperceptible; strongly dentate, from its origin projecting obliquely outward to a strong tooth on the fold in the discal cell, with a short tooth on the fold between the costal and subcostal veins; from discal tooth it receds to median vein a little nearer the body than its inception on the costa; from this it extends out in another tooth nearly twice as far out as the discal tooth, the point resting on the submedian fold, almost reaching the infection of the t.p. line, the points of both lines nearly obsolete in a white patch at this place that fades out into the general color; about the middle of the space from teh median vein to submedian fold a brownish black spur is sent our parallel with the median vein, terminating above the middle of the white patch; the line reaches the posterior margin by another inflexoon on submedian vein, and another outward tooth below the vein.

Fin Spines

Isolated teeth from the Middle Permian (early Guadalupian) Kaibab Formation of Arizona are described as a new species of the xenacanth shark genusBransonella. Bransonella tribulan. sp. is a small tooth in which the intermediate cusp is 65% of the length of the principal cusps and the cristae on the labial face extend down over the base, covering it, and bifurcating to form distinctive double crested ridges. Fin spines from the same localities in the Kaibab Formation show the characteristic xenacanth feature of a double row of large thorn-like denticles along the posterior margin.Bransonella tribulan. sp. is the only xenacanth shark known from the Kaibab Formation at present, however, due to the lack of articulated material the fin spines are attributed to ?Bransonella tribulan. sp. The ecomorphology ofBransonellasuggests a primitive, small, gracile, marine xenacanth that fed near the sea floor like the modern catsharks (Scyliorhinidae).

A New Species

A new palaemonid shrimp genus, Opaepupu gen. nov., is established to accommodate a new species of bivalve-associated shrimp, Opaepupu huna sp. nov. from Hawaii. A single mated pair, the female holotype and the male allotype, were found inside the trapezid bivalve Trapezium oblongum (Linnaeus, 1758) at a depth of 14 m in Kâne’ohe Bay, Hawai’i. The new genus is characterised by the rostrum being proximally broad, distally pointed, mid-dorsally carinate, and non-dentate; the anterolateral margin of the carapace without supraorbital, hepatic or epigastric teeth, but with a strong sharp antennal tooth; the sixth pleonite posteriorly unarmed; the telson medially depressed, with the dorsal surface armed with two pairs of submarginal cuspidate setae and with the posterior margin armed with two pairs of spiniform setae; the distolateral angle of the first article of the antennular peduncle without a sharp tooth; the mandible without a palp; the maxillular palp furnished with one long stiff seta dorsal to a small tooth-like extension; the first maxilliped without a palp; the third maxilliped not being operculate; the second pereiopods moderately robust, relatively slender, subequal, subsymmetrical, with simple teeth on the cutting edges of the fingers; the ambulatory pereiopods being slender, each ending in an elongate biunguiculate dactylus; and the uropodal exopod with a faint diaeresis and greatly reduced distolateral spiniform seta. The phylogenetic position of Opaepupu gen. nov. remains unclear, although it does not appear to be closely related to other bivalve-associated palaemonid genera.

Threshold Doses

Dutch-belted 1 to 2.5 kg anesthetized rabbits were exposed to either xenon or argon laser light administered in a broad band, designed to cover large areas of the retina. For laser exposure, the pupil was dilated with atropine sulfate 1% and pheny lephrine 10%. All of the laser generated power was within a band centered at 5145.0 Anstroms. Established threshold for 4 hour exposures to laser irradiation are in the order of 25-35 microwatts/cm2. Animals examined for ultrastructural changes received 4 hour threshold doses. These animals exhibited ERG, opthalmascopic, and histological changes consistent with threshold damage.One month following exposure the rabbits were killed with pentobarbitol. The eyes were immediately enucleated and dissected while bathed in 3% phosphate buffered gluteraldehyde.

General Appearance

The archaebacterium Methanospirillum hungatii has a sheath as part of its cell wall which is composed mainly of protein. Treatment with dithiothreitol or NaOH released the intact sheaths and electron micrographs of this material negatively stained with uranyl acetate showed flattened hollow tubes, about 0.5 μm diameter and several microns long, in which the patterns from the top and bottom were superimposed. Single layers, derived from broken tubes, were also seen and were more simply analysed. Figure 1 shows the general appearance of a single layer. There was a faint axial periodicity at 28.5 A, which was stronger at irregular multiples of 28.5 A (3 and 4 times were most common), and fine striations were also seen at about 3° to the tube axis. Low angle electron diffraction patterns (not shown) and optical diffraction patterns (Fig. 2) from these layers showed a complex meridian (as a result of the irregular nature of the repeat along the tube axis) which showed a clear maximum at 28.5 A, consistent with the basic subunit spacing.
