Long-nosed Slicker; Northern Sucker. Very abundant in Watson River, near Caribou, Yukon Ten-itory, where 76 specimens 4 1o inches long were seined July 18 and 19. Head ; depth ; eye 6; snout ; dorsal 10; anal 7; scales 20-110 to 120-15 to 17, (iO (o G5 in front of dorsal; length of pectoral in head; ventral ; height of dorsal Color in life, mottled olive; belly somewhat silvery; head brassy; fins all dull orange, the dorsal darker at Fig. 5.—Catostomus catostomus (Forster). Compared with specimens from Clear Creek, near Clearmont, Wyo., the Caribou specimens have considerably smaller scales (the Wyoming specimens having only 90 to 100 in course of lateral line), and more pointed head, with longer snout. This species has a wider distribution than any other member of the family. It was described origi- nally from the Hudson Bay region, and has since been recorded from various localities from New England westward to the headwaters of the Missouri and the Columbia and northward to Alaska. It is doubtless abundant in all suitable waters from the Hudson Bay region west and northwestward. At Great Slave Lake, on the Yukon, and elsewhere, it is a food fish of considerable importance, especially to the Indians. An examination of numerous specimens in the present collection indicates that the spawning season at Caribou is entirely over by July 19. Recorded from Nulato, Yu
