Brachiella lageniformis, hitherto known only from the Atlantic coast of Argentina, was found off the east coast of Vancouver Island, on the gills of Merluccius productus. Both male and female are described and illustrated in detail. The significance of this find for Szidat's views on the origin of the genus Merluccius is discussed. A proposal is made to suppress the genus Parabrachiella and to place all its five species (P. rostrata, P. insidiosa, P. australis, P. spinicephala, and P. incurva) in the genus Brachiella.

Records are given of two species and a variety new to western Canada and notes on three other species already known from the region. A new species, Aricidea lopezi, and four species new to western North America, are described from the neighbourhood of Friday Harbour, Washington.

Separate proximate analyses of the flesh and skin of three freshly-caught ling cod (Ophiodon elongatus) from the east coast of Vancouver island are reported. Average percentages of protein in the flesh and skin were 18.1 and 26.9 (moist) or 87.0 and 88.5 (dry); ash, 1.2 and 2.5 (moist); fat, negligible; Calories per 100 g. (moist), 81 and 117.

Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) plantations on the east coast of Vancouver Island, British Columbia, were examined to determine the effect of animal feeding upon height growth.Length of internodes and evidence of past leader damage were recorded and cumulative average height-age growth curves compared for undamaged trees and for trees suffering various intensities of damage.The average reduction in tree height attributable to animal feeding in heavily browsed plantations varied from one-half to two feet over a period of 8 to 10 years. It is unlikely that either tree volume or quality at rotation age would be seriously affected.Exposed trees were browsed more heavily than those protected by vegetation or logging slash.

A new species of Leuckartiara, Leuckartiara foersteri n.sp., is described and illustrated. It is differentiated from all other species of the genus by marginal tentacles without abaxial spurs, and gonads with parallel folds, situated on adradial sides of cross-shaped manubrium with no distinct interradial connection.

The abundance of common mergansers (Mergus merganser) was monitored on four salmon-producing streams on the east coast of Vancouver Island, B.C., during the spring and summer of 1980–83. Overall, merganser abundance declined steadily from March through June but increased following recruitment of juvenile birds. Mergansers congregated on streams where juvenile salmonid migrations were enhanced by hatcheries or spawning channels. Movement between streams was evident from inverse trends in abundance on three adjacent streams differing in juvenile salmonid production. At least 8 of 12 mergansers resighted after being marked and released on the Big Qualicum River visited other nearby streams. Flock-size distributions predicted by an equilibrium arrival–departure model were consistent with those observed during May–mid-june, but not those during late June. Social interactions and reduced flight activity appeared to influence dispersion to a greater extent during late June to August so that assumptions of the model were violated. A similar model was used to predict aggregation patterns on hatchery streams from observed relationships between fish availability and frequencies of arrival and departure. The aggregation model provides a parsimonious explanation of merganser aggregation patterns during March–June and is a potentially useful tool for designing fish release schedules to minimize predation by mergansers.

The following new species of littoral enchytraeid are described from the east coast of Vancouver Island, British Columbia—Enchytraeus cryptosetosus, Lumbricillus mirabilis, L. vancouverensis, L. georgiensis, L. qualicumensis, L. belli. These descriptions bring the number of North American Enchytraeus spp. to 6 and that of Lumbricillus spp. to 13. Existing evidence suggests that the enchytraeid fauna of the Pacific slope is quite distinct from that of the rest of North America and may have closer affinities with that of the northwest Pacific.
