Four species of the enchytraeid oligochaete genus Marionina from intertidal habitats are added to the British Columbia species list: Marionina klaskisharum sp. nov., M. nevisensis (Righi and Kanner, 1979), M. southerni Cernosvitov, 1937, and M. glandulifera (Jansson, 1960). Marionina nevisensis is asetate; M. klaskisharum has setal bundles ventrally in II to V, each represented by a single seta; M. glandulifera has only ventral, bisetate setal bundles; and M. southerni has lateral and ventral bisetate bundles in all segments except laterally in II. Marionina nevisensis is elevated from a subspecies of M. achaeta Lasserre, 1964 because of structural differences of their spermathecae and seminal vesicles. The ranges of M. charlottensis Coates, 1980 and M. nevisensis Coates, 1980 are extended, respectively, south to northern California and to include the entire British Columbia coastline.

Four new shallow water species of the genus Pacifigorgia were found in recent surveys along the Pacific coast of Panama. One of the species was only found in dense patches at two shallow seamount-like localities inside the Coiba National Park, Gulf of Chiriqu . Two other species were patchily distributed at several localities in the Gulf of Chiriqu . A fourth species was widely distributed around the gulfs of Chiriqu and Panama encompassing a broad range of habitats and depths. The new species are described and illustrated in detail with scanning electron micrographs (SEM) of the sclerites, and colour photographs of the colony forms. The suspected occurrence of a particular Pacifigorgia species for this region is confirmed and two other new records are added to the species list. With the new four species, a total of 15 are established for Panama, making 31 species for the eastern Pacific to date.

Seven previously described and seven new taxa of gyrodiform naticoids from West Coast Late Cretaceous–Paleocene age strata are discussed. Gyrodes (Gyrodes) dowelli White of Turonian age is a typical Gyrodes; G. robustus Waring from the Paleocene has the shape of Gyrodes s.s. but lacks the crenulations. G. greeni Murphy and Rodda, G. yolensis n. sp., G. quercus n. sp., G. banites n. sp., G. canadensis Whiteaves, G. pacificus n. sp., and G. expansus Gabb comprise the new subgenus Sohlella, which thus ranges from Cenomanian through Maastrichtian. Gyrodes robsauli n. sp. resembles “Polinices” (Hypterita) helicoides (Gray), and Hypterita is reassigned to the Gyrodinae as a subgenus of Gyrodes. Gyrodes onensis n. sp. of Albian age is similar to the G. americanus group of Sohl (1960). Three texa—Natica allisoni (Murphy and Rodda) of Cenomanian age and N. conradiana Gabb and N. conradiana vacculae n. subsp. of Turonian age—which have all been previously considered to be Gyrodes are placed in Natica. Well marked relict color patterns on N. conradiana and N. conradiana vacculae suggest that these naticids from northern California and southern British Columbia were tropical forms.Diversity of taxa and size of specimens are reduced at the end of the Turonian, suggesting a change in West Coast marine conditions at that time.

Descriptions of six new species of marine or estuarine tubificid oligochaetes are given. Tubificoides kozloffi sp.nov., and Tubificoides brevicoleus sp.nov. are described from intertidal habitats of Washington and British Columbia. Tubificoides foliatus sp.nov., a species previously identified as belonging to the Tubificoides gabriellae complex, is described from California and British Columbia. Tubificoides cuspisetosus sp.nov., Tubificoides palacoleus sp.nov., and Tubificoides crenacoleus sp.nov. are described from the Arctic. A key to the species-groups of Tubificoides is given.

The Way

Semi-Subterranean houses with an entrance through the roof are a well known feature of the interior of British Columbia, having been described for the Thompson, the Chilcotin, the Shuswap and others of the upper Fraser River valley. They have, in fact, an even wider distribution east of the Coast and Cascade Ranges, extending south over the Plateau and into northern California. Although this type of dwelling existed among the Aleuts, it appears that the coastal people to the south of them, even in Alaska, were either unfamiliar with the pattern or rejected it in favor of others. Sporadically, along the Pacific Coast all the way from California to Bering Sea, house floors were excavated to varying depths, sometimes even to two levels; but, everywhere, the houses characteristically lack the roof entrance and, except for sweathouses in the south and Bering Sea Eskimo dwellings in the north, even the idea of an earth covering is absent. In view of this fundamental divergence, it is interesting that subterranean structures do appear in several places on the coast of British Columbia.

St. Helens is one of a group of high volcanic peaks that dominate the Cascade Range between northern California and southern British Columbia, Canada. The distribution is in a band that roughly parallels the coastline of the so-called “Ring of Fire,” a near circular array of volcanoes located on islands, peninsulas and the margins of continents that rim the Pacific Ocean.

Rocky Mountain Wood Tick

Tick paralysis continues to be one of the most baffling and fascinating tickborne diseases in Canada. It was first reported in this country by Todd in 1912. Since then about 250 human cases, including 28 deaths, have been recorded from British Columbia. Outbreaks in cattle have affected up to 400 animals at a time, with losses in a herd as high as 65 head. Although the disease is most common in the Pacific northwest, where it is caused by the Rocky Mountain wood tick, Dermacentor andersoni Stiles, it has lately been reported as far south as Florida and has been produced by Dermacentor variabilis Say, Amblyomma maculatum Koch, and A. americanum (L.) (Gregson, 1953). The symptoms include a gradual ascending symmetrical flaccid paralysis. Apparently only man, sheep, cattle, dogs, and buffalo (one known instance) are susceptible, but even these may not necessarily be paralysed.

Conservation Evaluation

In Canada, Dwarf Woolly-heads, Psilocarphus brevissimus var. brevissimus, is restricted to the Similkameen River valley, south of Princeton in southwestern British Columbia and the extreme southeast and southwest corners of Alberta and Saskatchewan, respectively. This paper deals with the three British Columbia populations which represent the northwestern limit of the species which ranges from south-central British Columbia, southward in the western United States to Montana, Idaho, Washington, Oregon, Nevada, Utah, Wyoming, California and Baja California, Mexico. In British Columbia, P. brevissimus is associated with calcareous vernal pools and ephemeral pond edges in large forest openings. This habitat is rare in the area the few existing populations could easily be extirpated or degraded through slight changes in groundwater levels, coalbed methane gas drilling, housing development or recreational vehicles.
