An incomplete specimen of Desmatochelys cf. D. lowi (Reptilia: Chelonioidea) from the Trent River Formation (Santonian–Campanian) of the Comox Basin of eastern Vancouver Island is the first documented account of Cretaceous marine vertebrates from the Pacific coast of Canada. It represents both stratigraphic and geographic range extensions for the genus Desmatochelys.

A new fauna of fossil marine reptiles is described from the Late Cretaceous Nanaimo Group of Vancouver Island. The fossils are from the Haslam and Pender formations (upper Santonian) near Courtenay, British Columbia, and include elasmosaurid plesiosaurs, turtles, and mosasaurs. This is only the second fauna of Late Cretaceous marine reptiles known from the Pacific Coast, the other being from the Moreno Formation of California (Maastrichtian). The new Nanaimo Group fossils are some 15 million years older than those from the Moreno Formation. However, like the California fauna, there are no polycotylid plesiosaurs, and one of the mosasaurs is a new genus. This reinforces the provinciality of the Pacific faunas and their isolation from contemporaneous faunas in the Western Interior Seaway.

A New Species

A new species Bradyidius saanichi from Saanich Inlet, Vancouver Island, British Columbia, Canada, is described and illustrated in detail. This species is closely related to B. pacificus (Brodsky, 1950) among the six previously known species in the genus, but can be readily distinguished from the latter by the strongly divergent rostral rami in addition to some other differences.

First Time

The coccolithophorid Scyphosphaera apsteinii is here reported for the first time from waters off the west coast of the Baja California Peninsula. Scypho­sphaera apsteinii is the type species of the genus Scyphosphaera and had hitherto been recorded only in the Atlantic and Indian Oceans, the Gulf of Mexico, the Mediterranean, and the Caribbean Seas. Specimens were found in samples collected in nets off Isla de Guadalupe in January 2013. This recording thus extends the geographical distribution of S. apsteinii from the Central Pacific (Hawaii) to the Eastern Pacific (NW Mexico).

Buffleheads are punctual in their return to wintering grounds on the Pacific coast. First arrivals appeared in Shoal Harbour Migratory Bird Sanctuary, southeastern Vancouver Island, on the 288th day of the year on average (± S.D. 2.3; n = 10), that is, 15 October. This vanguard preceded the first peak influx by about 15–20 days, and a second influx by about 24–26 days. First arrivals usually appeared by mid-morning, and included singles (females on two occasions) and small flocks of up to eight. First arrivals may represent a photoperiodic threshold, whereas subsequent peak influxes represent climatic thresholds associated with freeze-up. The phenology of Bufflehead autumn migrations is a good proxy indicator of the advance of the zero degree isotherm, and thus of climatic variability. The timing of their autumn migrations does not appear to have changed in the last half of the twentieth century, consistent with evidence that freeze-up has not advanced. Monitoring of their migrations, in conjunction with shore-based observations of freeze-up, would validate one-dimensional thermodynamic models of freeze-up, and provide a more ecologically meaningful index of climate change, at minimal cost.

Aporocotyle macfarlani Holmes, 1971, was found in five species of Sebastes taken from the inland waters around the San Juan Islands, Washington, or the inshore waters around Vancouver Island, B.C. Psettarium sebastodorum Holmes, 1971, was found in 14 species of Sebastes from the same locations or from deeper offshore waters west of Vancouver Island. The two flukes have different dominant hosts. Their numbers show different relations with depth. Aporocotyle macfarlani appears to be associated with fish that frequent reefs.Aporocotyle macfarlani occupies the lumen of the afferent branchial arteries, the ventral aorta, and rarely parts of the heart; P. sebastodorum is threaded into the intertrabecular spaces of the ventricle and atrium. The overlap in the distributions of the two species is reduced in concurrent infections.

Phoronopsis Harmeri

Six phoronids from the west coast of North America, Phoronis vancouverensis, Phoronis pallida, Phoronis psammophila, Phoronis ovalis, Phoronopsis harmeri, and one that is possibly Phoronis architecta, are described. Phoronopsis harmeri is considered to be synonymous with Phoronopsis viridis. Taxonomic relationships within the Phoronidea are discussed. It is suggested that the phylum may most naturally be divided into four categories of wide geographic range. The characteristics of each of these categories are discussed.
