Brood Amalgamation

Least Sandpipers (Calidris minutila) were studied on the Queen Charlotte Islands, British Columbia, over five breeding seasons. Brood amalgamation and care of foreign chicks occur regularly, though at low incidence, among the approximately 90 breeding pairs there. Such behavior is probably important to chick survival and has little impact on adult fitness. Brood amalgamation and alloparental care appear to be widespread in calidridine sandpipers.

Previous observations in British Columbia have shown that at one stage in the Glacial period—that of maximum glaciation—a great confluent ice-mass has occupied the region which may be named the Interior Plateau, between the Coast Mountains and Gold and Eocky Mountain Kanges. From the 55th to the 49th parallel this great glacier has left traces of its general southward or southeastward movement, which are distinct from those of subsequent local glaciers. The southern extensions or terminations of this confluent glacier, in Washington and Idaho Territories, have quite recently been examined by Mr. Bailley Willis and Prof. T. C. Chamberlin, of the U.S. Geological Survey. There is, further, evidence to show that this inland-ice flowed also, by transverse valleys and gaps, across the Coast Range, and that the fiords of the coast were thus deeply filled with glacier-ice which, supplemented by that originating on the Coast Range itself, buried the entire great valley which separates Vancouver Island from the mainland and discharged seaward round both ends of the island. Further north, the glacier extending from the mainland coast touched the northern shores of the Queen Charlotte Islands.

A New Species

Occella impi, a new species of sea poacher, is described from a single specimen captured in the Queen Charlotte Islands, British Columbia. Occella impi differs from other species of Occella in having spinous plates on the breast, the anus nearer the anal fin, and fewer anal rays; also, the numbers of bony body plates are distinctive. A key to the known species of Occella, based primarily on the numbers of bony body plates, is included. The size of the maxillary barbel and number of infralateral plates are shown to be characteristic of the genera Occella and Stellerina.

Generic Distribution

Tingupa tlingitorum n. sp. (Diplopoda: Chordeumatida: Tingupidae) is proposed for male and female millipeds from Haines, Alaska, USA. It constitutes the first Alaskan record of the family and third of the order, and represents generic and familial range extensions of ca. 1,050 mi (1,680 km) from the previous northern limit in Oregon. Tingupa sp. is also reported from Idaho, the first generic and familial records from this state, and the Queen Charlotte Islands, the first records for both Canada and British Columbia. A revised key to species and a new familial distribution map are presented.
