The stratigraphy of the Upper Cretaceous Nanaimo Group of the Vancouver Island region is revised on the bases of new fossil and field data. Previously unrecognized turbidite facies of the Haslam Formation are proposed as the new Cowichan Member of the Haslam Formation. This member either overlies or intertongues with the new Haslam Creek Member of the Haslam Formation. The Extension–Protection Formation is subdivided into three formations: the lower Extension Formation, the middle Pender Formation (new name) and the upper Protection Formation.The macrofossil zonal succession can be revised to include a new local-range zone superjacent to the Schmidti Zone and subjacent to the Vancouverense Zone named the Chicoensis Zone, based on the Nanaimo Group occurrences of Baculites chicoensis Trask and Submortoniceras chicoense (Trask). Another new zone is proposed superjacent to the Vancouverense Zone and subjacent to the Suciaensis Zone, named the Paciflcum Zone. This latter zone is based on the local Nanaimo Group ranges of Metaplacenticeras cf. M. pacificum (Smith) and Baculites rex Anderson.

This special volume of CJL/RCL is the first collection of papers devoted specifically to the Southern Wakashan languages Makah, Ditidaht (also known as Nitinat), and Nuu-chah-nulth (also known as Nootka). These three closely related languages form a continuum stretching from the northwest tip of Washington State to northwest Vancouver Island in British Columbia. The Southern Wakashan languages are remarkable for the typologically unusual traits they exhibit in virtually all areas of their grammars. These properties were first illuminated by Edward Sapir in his foundational work on Nuu-chah-nulth (1911, 1915, 1921; Sapir and Swadesh 1939), which helped thrust Wakashan to the forefront of early Amerindian scholarship. The papers brought together in this volume reflect a recent resurgence of interest in Southern Wakashan, and highlight the potential of lesser-studied languages to contribute to linguistic theory, as well as the range of insights that theoretically informed perspectives can bring to the grammatical description of these languages.

The hydromedusa Geomackiea zephyrolata gen. nov., sp. nov. is described and illustrated. It has been placed in the subfamily Protiarinae of the family Pandeidae on the basis of its stomach and gonad morphology and the four large perradial tentacles with conical basal bulbs. A new genus has been erected because the medusa is supplied with four broad interradial bulbs, each rimmed by up to eight closely packed solid tentaculae. A total of 29 specimens with bell heights of 0.9–3.5 mm have been collected in the plankton of Saanich Inlet, British Columbia, and Friday Harbor, Washington, between 1978 and 1981. Juvenile as well as adult specimens are described and the cnidome, gametes, seasonal and vertical distributions, and taxonomic affinities within the family Pandeidae are discussed.

A New Species

A new porcellanid crab, Petrolisthes landsendi Garassino & Nyborg n. sp., from the Upper Cretaceous (upper Santonian) Nanaimo Group of Vancouver Island (British Columbia, Canada) is herein described. Petrolisthes landsendi Garassino & Nyborg n. sp. represents the oldest species of Petrolisthes Stimpson, 1858 and is the first species from the northeastern Pacific, thus expanding the stratigraphical age and geographical range of the genus.

Okanagan Highlands

We survey the known avian fossils from Ypresian (early Eocene) fossil sites of the North American Okanagan Highlands, mainly in British Columbia (Canada). All specimens represent taxa that were previously unknown from the Eocene of far-western North America. Wings from the McAbee site are tentatively referred to the Gaviiformes and would constitute the earliest fossil record of this group of birds. A postcranial skeleton from Driftwood Canyon is tentatively assigned to the Songziidae, a taxon originally established for fossils from the Ypresian of China. Two skeletons from Driftwood Canyon and the McAbee site are tentatively referred to Coliiformes and Zygodactylidae, respectively, whereas three further fossils from McAbee, Blakeburn, and Republic (Washington, USA) are too poorly preserved for even a tentative assignment. The specimens from the Okanagan Highlands inhabited relatively high paleoaltitudes with microthermal climates (except Quilchena: lower mesothermal) and mild winters, whereas most other Ypresian fossil birds are from much warmer lowland paleoenvironments with upper mesothermal to megathermal climates. The putative occurrence of a gaviiform bird is particularly noteworthy because diving birds are unknown from other lacustrine Ypresian fossil sites of the Northern Hemisphere. The bones of the putative zygodactylid show a sulphurous colouration, and we hypothesize that this highly unusual preservation may be due to the metabolic activity of sulphide-oxidizing bacteria.
