Richards (9) recognized five species of Lecanium for Canada – namely L. coryli L., L. cerasifex Fitch, L. tiliae L., L. nigrofasciatum Pergande and L. caryae Fitch. L. coryli L. and L. cerasifex Fitch were distributed from British Columbia to Nova Scotia; L. tiliae L. occurred only in British Columbia.Further, Richards (9) drew the following conclusions:1.) L. coryli is the L. corni Bouché of Marchal (1908) and of most European workers but is not the L. corni of North American workers.2.) L. corni Bouché of Sanders (1909) and subsequent North American workers is a mixture of two species, L. corni Bouché of Marchal and L. cerasifex Fitch of Richards.3.) L. tiliae is L. coryli of Marchal (1908) and subsequent workers.

Early Cenozoic

Early Eocene fossil floras from British Columbia are a rich resource for reconstructing western North American early Cenozoic climate. The best known of these floras reflect cooler (MAT ≤ 15 °C) upland forest communities in contrast to coeval (MAT ≥ 18 °C) forests in lowland western North American sites. Of particular interest is whether Early Eocene climates were monsoonal (highly seasonal precipitation). The McAbee site is a 52.9 ± 0.83 Ma 0.5 km outcrop of bedded lacustrine shale interbedded with volcanic ash. In this report two historical megaflora collections that were collected independently from different stratigraphic levels and (or) laterally separated by ∼100–200 m in the 1980s (University of Saskatchewan) and 2000s (Brandon University) are investigated to (i) assess whether they represent the same leaf population, (ii) assess whether a combined collection yields more precise climate estimates, and (iii) reconstruct paleoclimate to assess the character of regional Early Eocene precipitation seasonality. Combined, the two samples yielded 43 dicot leaf morphotypes. Analysis of leaf size distribution using ANOVA showed no difference between the two samples, and thus they were combined for climate analysis. Climate analysis using leaf physiognomy agrees with previous estimates for McAbee and other regional megafloras, indicating a warm (MAT ∼8–13 °C), mild (CMMT ∼5 °C), moist (MAP > 100 cm/year) ever-wet, non-monsoonal climate. Additionally, we recommend that climate analyses derived from leaf fossils should be based on samples collected within a stratigraphically constrained quarry area to capture a snapshot of climate in time rather than time-averaged estimates derived from multiple quarry sites representing different stratigraphic levels within a fossil site.

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.

Woolly Mammoth

A well-preserved molar of a woolly mammoth (Mammuthus primigenius) was recovered from deposits at Chestermere Lake near Calgary. It is probably of late Wisconsin age, and is one of several mammoth fossils collected from Pleistocene sediments in the Calgary area.The Chestermere Lake specimen is considered in relation to 94 records of mammoth cheek teeth from the western Canadian provinces. Of the 94 records, 5 are from Manitoba, 35 are from Saskatchewan, 37 are from Alberta, and 17 are from British Columbia. In addition to specimens of woolly mammoths, remains of Columbian (Mammuthus columbi), imperial (Mammuthus imperator), and southern mammoths (Mammuthus meridionalis) have been collected from Pleistocene deposits of southwestern Canada. Some problems concerning the relationships of North American and Eurasian mammoths are mentioned.

New ammonite faunas are described from sections along Bighorn and Scalp creeks in central-western Alberta where Lower Jurassic parts of the Fernie Formation are exposed. The first record of the upper Sinemurian Obtusum Zone from the Fernie is based on the occurrence of Asteroceras cf. stellare and Epophioceras cf. breoni in the basal pebbly coquina on Bighorn Creek. The overlying Red Deer Member has yielded Amaltheus cf. stokesi, representing the upper Pliensbachian Margaritatus Zone; in immediately superjacent strata the first North American examples of ?Amauroceras occur together with Protogrammoceras and ?Aveyroniceras. In the basal parts of the overlying Poker Chip Shale a fauna including Harpoceras cf. falciferum, Harpoceratoides, Polyplectus cf. subplanatus, Hildaites cf. serpentiniformis, and Dactylioceras cf. athleticum is correlated with the lower Toarcian Falciferum Zone.The upper parts of the Poker Chip Shale on Fording River in southeastern British Columbia contain a fauna representing some part of the upper Toarcian, but owing to poor preservation, generic identifications are only tentatively made.

This article explores how longer distance cycling can advance interspecies mobility justice, a theory of (im)mobilities and justice that includes other-than-human persons and habitats as worthy of our positive moral obligations. I argue that longer distance cycling can advance interspecies mobility justice by promoting socially inclusive and ecologically good cycling practices that redress the active travel poverty of marginalized and colonized populations, while replacing rather than augmenting auto roads with active travel routes that help humans respect other species. The article theorizes longer distance cycling not as some specific number of kilometres, but rather as the social production of cycling space across gentrified central cities, struggling inner suburbs, outer exurbs and rural countrysides. To explore this argument my analysis focuses on Canada, an extreme context for longer distance cycling. I offer a comparison of two case studies, situated on the country’s west and east coasts, Vancouver, British Columbia and Halifax, Nova Scotia, drawing on an ongoing ethnographic study of cycling practices and politics in Canada.
