A brown pocket rot of Sitka spruce (Picea sitchensis Carr.) occurs in stands on the Queen Charlotte Islands, B.C. The decay, the sporophore associated with it, and the cultural characters of the fungus are described. The causal fungus is regarded as a new species and is described as Lentinus Kauffmanii sp. nov. by Dr. Alexander H. Smith, University of Michigan.

During the past few years Mr. S. F. Condrashoff, Forest Research Laboratory, Canada Department of Forestry, Victoria, B.C., has been studying the insect pests of Sitka spruce on the Queen Charlotte Islands. One of these is a new species and the description of it is presented here to enable Mr. Condrashoff to describe the larva in a companion paper that follows (Can. Ent. 98: 703–706 (1966), in press).

Occella impi, a new species of sea poacher, is described from a single specimen captured in the Queen Charlotte Islands, British Columbia. Occella impi differs from other species of Occella in having spinous plates on the breast, the anus nearer the anal fin, and fewer anal rays; also, the numbers of bony body plates are distinctive. A key to the known species of Occella, based primarily on the numbers of bony body plates, is included. The size of the maxillary barbel and number of infralateral plates are shown to be characteristic of the genera Occella and Stellerina.

SynopsisThe natural distribution of Sitka spruce is examined in relation to the species' role in British forestry. Particular attention is therefore given to a description of habitats on the Queen Charlotte Islands, and also on the adjacent mainland of British Columbia where Sitka spruce is sympatric with white spruce (Picea glauca) and hybridisation occurs. Examples of genetic variation are given and it is suggested that a knowledge of the genecologv of the species in its natural habitat would help to elucidate its full ecological and genetic potential in Britain.

This is the second in a series of papers intended to establish a Lower Jurassic ammonite zonation that takes into account the biostratigraphic and biogeographic peculiarities of the North American succession. In North America the lower boundary of the Toarcian is drawn at the first appearance of Dactylioceras above the last occurrence of Amaltheus and Fanninoceras. The lower Toarcian is represented by the Kanense Zone; the middle Toarcian by the Planulata and Crassicosta zones; and the upper Toarcian by the Hillebrandti and Yakounensis zones. Section 5 on the Yakoun River in the Queen Charlotte Islands is designated the stratotype for the Planulata, Crassicosta, and Hillebrandti zones; section 3 on the Yakoun River is designated the stratotype for the Yakounensis Zone; an ideal stratotype for the Kanense Zone is not presently known. Reference sections further illustrating the faunal associations that characterize the zones are designated in eastern Oregon (Snowshoe Formation) and northern British Columbia (Spatsizi Group). The Dactylioceratidae, Harpoceratinae, and Hildoceratinae provide the most important zonal indicators for the lower Toarcian; Dactylioceratidae, Phymatoceratinae, and Bouleiceratinae for the middle Toarcian; and Phymatoceratinae, Grammoceratinae, and Hammatoceratinae for the upper Toarcian. Phymatoceras hillebrandti is described as a new species.

Local damage on the Queen Charlotte Islands to seed of Sitka spruce, Picea sitchensis, has led to the discovery of the causal agent, a new cone rust. At the same time a new Chrysomyxa on the one-flowered pyrola, Moneses uniflora, was discovered in the same area. Evidence from observations in the field, from controlled inoculations, and from the similarity of markings on aeciospores and urediniospores has led to the conclusion that the cone rust is the aecial stage of an undescribed Chrysomyxa. The rust has been described and named Chrysomyxa monesis. It is feared that the rust may cause serious damage to spruce seed abroad unless its spread is prevented. Surface sterilization of spruce seed before export is therefore recommended.

A species of Lecanora in the L. dispersa group, with a well-developed pale thallus and a granular epihymenium, resembling L. albescens , is found exclusively on shoreline rocks and appears to be new. It is described as Lecanora schofieldii  sp. nov., found mainly in the Pacific Northwest, but also rarely on the northeast coast. Its distinctions from similar species on shoreline rocks are given, together with a key for their identification. The first western record of L. xylophila from rocks is given.

A new species of South American planorbid snail, Biomphalaria occidentalis, is described. It is indistinguishable from B. tenagophila (Orbigny, 1835), by the characteristics of the shell and of most organs of the genital system. In B. tenagophila there is a pouch on the ventral wall of the vagina (Fig. 4A, vp), absent in B. occidentalis (Fig. 3A), and on the ventral wall of the vagina (Fig. 4A, vp), absent in B. occidentalis (Fig. 3A), and the prepuce is much wider than the penial sheath, its width increasing distalward (Fig. 4, ps,pp), whereas in B. occidentalis the prepuce is wider than the penial sheath but keeps about the same width all along (Fig.3, ps, pp). The two species are biologically separate by absolute reproductive isolation. The geographical distribution of B. occidentalis is shown in Fig. 14. So far it has been found in the Brazilian states of Acre, Amazonas (?), Mato Grosso, Mato Grosso do Sul and Paraná, and in Paraguay. Its type-locality is Campo Grande, state of Mato Grosso do sul, where it was collected from several biotopes related to affluents of the Aquiduana river, chiefly Córrego Prosa and Córrego Ceroula. Specimens were deposited in the following malacological collections: Instituto Oswaldo Cruz, Rio de Janeiro; Academy of Natural Sciences, Philadelphia; Museum of Zoology, University of Michigan; and British Museum (Natural History).

The height-age model for Sitka spruce (Picea sitchensis (Bong.) Carr.) currently recommended for use in British Columbia has poor extrapolation properties. Therefore, a new height-age model for Sitka spruce using stem analysis data collected from the Queen Charlotte Islands was developed. Care was taken to meet the standard regression assumptions. In particular, accounting for within-plot serial correlation improved the extrapolation abilities of the model by eliminating the crossing-over effect. The new model is being recommended for use in British Columbia because it offers better extrapolated height and site index estimates without sacrificing accuracy at young ages. Key words: Sitka spruce, site index, height-age model, serial correlation, nonlinear regression, extrapolation, model properties

AbstractDiptera caught in malaise traps set in forests of Sitka spruce, Picea sitchensis (Bon.) Carrière, in the Carmanah Valley, on Vancouver Island, British Columbia, included two new species of Sphaeroceridae. Minilimosina sitka Marshall sp.nov. and Phthitia squamosa Marshall sp.nov. are described for the first time and compared with related species. Fourteen other sphaerocerid species caught with these species are listed.
