Specimen Material

A total of 44 nematode taxa were encountered in an examination of six collections of marine nematodes from the Minas Basin – Scots Bay area of the Bay of Fundy, Nova Scotia. Of these only 16 were sufficiently represented by adequate specimen material to permit proper species identification. Fifteen species were identified as being European species while one is described as new to science. Haliplectus cylindrocaudatus n. sp. differs from other Haliplectus spp. by its cylindrical tail terminus. Ptycholaimellus Cobb, 1920 is reestablished as a valid genus and is considered distinctive in that the cephalic setae are inserted on a protrusile vestibular region. Hypodontolaimus monodon Schuurmans Stekhoven, 1942 is transferred to this genus. Mesotheristus Wieser, 1956 is defined as having lateral alae and the male of the type species, M. setosus, as possessing two opposed and outstretched testes. Daptonema fimbriatum Cobb, 1920 and Theristus (Trichotheristus) erectus Wieser and Hopper, 1967 are transferred to Mesotheristus. Theristus (Cylindrotheristus) oxyuroides Schuurmans Stekhoven sensu Wieser and Hopper, 1967 is renamed Cylindrotheristus miamiensis n. sp.

Hyperoodon Ampullatus

A 615-cm male northern bottlenose whale (Hyperoodon ampullatus) stranded in Cobequid Bay, Bay of Fundy, in early October 1969. The skull, mandible, tympano-periotics, and teeth are described and illustrated. Five growth layers in the lower teeth place the animal below a growth curve based on samples from the Labrador Sea taken in May and June. A summary of nine other North American occurrences of 12 individuals, mainly south of Sable Island, indicates a winter migration to waters offshore of Massachusetts and Rhode Island.

Biological Factors

Crustacean and rotifer plankton assemblages of 93 lakes in Labrador, 107 in Newfoundland, and 142 in New Brunswick – Nova Scotia were investigated for evidence of correlations with lake morphometric, chemical, or biological factors. Labrador assemblages were almost completely lacking in identifiable structure. Newfoundland species clustered into two groups of different body size, suggesting the influence of fish predation. Only one species in Labrador and Newfoundland was significantly correlated with a derived factor related to lake water buffering capacity. New Brunswick – Nova Scotia species clustered into two groups, one featuring significant positive and the other significant negative correlations with the buffering factor. From this we conclude that acidification is having an impact on the limnetic zooplankton of these two provinces. Multiple discriminant analysis was used to demonstrate that New Brunswick – Nova Scotia lakes differing in their buffering capacity were also distinct in zooplankton composition. Lakes with low factor scores (low pH, alkalinity, and calcium) were mainly located in the Bay of Fundy region; this area has above average fog and precipitation, and lies within the summer air flow carrying pollutants from the south.

A New Species

AbstractThe type material of most European nominal species previously placed in Rhoptromeris and of some other species is studied. Notes are given on the type material, 10 lectotypes are designated and the identity of the species is discussed. Three valid Rhoptromeris species are found: R. heptoma (Hartig) [type species], R. villosa (Hartig) and R. rufiventris (Giraud) n.comb. The latter is the type species of Hexamerocera Kieffer which is synonymized with Rhoptromeris. The genus Rhoptromeris is described and compared with related genera. The three species found to be valid are figured and redescribed, and also a new species, R. nigriventris, is described from Sweden. R. heptoma is an important parasitoid of Oscinella frit (L.) (Dipt.: Chloropidae).
