♀. Eyes small, ciliate: palpi light ochreous with rough dark hairs; vestiture of head and thorax rough, hairy, dark gray; abdomen light gray with yellow terminal tuft. Primaries pale yellowish, heavily sprinkled with black, producing a dull olivaceous appearance; maculation distinct; t. a. line heavy, black, upright, forming three moderate outcurves of which the central one is the largest, t. p. line dentate, ercurved below costa, then inwardly oblique to inner margin with slight incurve below cell, faintly marked outwardly with pale yellow; median shade diffuse, oblique from costa across reniform, then close and parallel to t. p. line; orbicular moderately large, round, pale-filled, outlined in black; reniform rather narrow, upright, partially outlined in black and obscured by median shade; subterminal and terminal areas rather evenly dark smoky; s. t. line obscure, pale, rather even, emphasized by slight smoky preceding shade; fringes blackish in basal half, cut opposite veins by pale ochreous, paler smoky in outer half.

Nemoria darwiniata Dyar. A single ♀, June 15.Nemoria hudsonaria Tayl. Quite common during the latter half of June. In a few of the specimens the inner transverse lines are obsolete and these could as well be placed under unilinearia Tayl. as under hudsonaria. I am not sure at the present time whether the differences given by Taylor are of specific value and until I can study the matter further I use the older of the two names.

Cassianastraea is an enigmatic colonial Triassic cnidarian first described as a coral but subsequently referred to the Hydrozoa. We report here the first occurrence in Canada of fossils we designate as Cassianastraea sp. from the Williston Lake region of British Columbia. The specimens come from older collections of the Geological Survey of Canada, collected in Upper Triassic (Carnian) strata assigned to either the Ludington or Baldonnel Formations. While well known in reef associations of the former Tethys region, Cassianiastraea is relatively rare in North America. The Carnian Baldonnel Formation contains the earliest coral reefs from the North American craton and we suspect that Cassianastraea sp. also came from this reef association.

Sericosema wilsonensis C. 8; S. Two males which seem to belong to this species according to genitalia were taken on July 8; the species differs from juturnaria in its sinaller size, lack of the strong ruddy tinges on the underside and in the position of the dark line on underside of secondaries which in wilsonensis is nearer the middle of the wing and more evenly rounded. There is a further specimen in the Canadian National Collection from Salmon Arm, B. C., July 18 (A. A. Dennys). The species does not appear to have been previously recorded from British Columbia.

Primary productivity in Babine Lake, British Columbia, as measured by the C14 in situ method in 1966 was slightly lower in the North Arm (outlet) and Morrison Arm (an inlet) than in the main lake region. An unusually high rate of photosynthesis at one part of the main lake in September may have been related to the decomposition of salmon carcasses in a nearby stream. Morrison Lake, a major tributary, was much lower in rate of photosynthesis, pH, alkalinity, compensation depth, and total dissolved solids than any part of Babine Lake. The rate of carbon fixation of Babine Lake was much less on a per unit area basis than those reported by other workers for the majority of 24 sockeye salmon lakes in southwestern Alaska but was similar to most per unit volume of the euphotic layer. Much of this difference is attributable to a shallower euphotic zone in Babine Lake. Ranked with the 24 Alaskan lakes, Babine was first in alkalinity, third in TDS, and fifth in pH.The productivity measurements suggest that the carrying capacity for sockeye salmon per unit of nursery area of the main lake region is at least as great as that of the North Arm.
