The Canadian field-naturalist. 1976 Notes An Extension of the Range of the Northern Long-toed Salamander, Ambystoma macrodactylum columbianum in Alaska Ambystoma macrodactylum columbianum (Ferguson 1961) has been reported to occur in southeastern Alaska by Stebbins (1966), Ferguson (1961, 1963), and Hodge (1973). Hodge (1973), however, provided the only locality record and specimen from the state. The collection of a single specimen from the Taku River (58°32' N, 133°45' W) near Colby's Landing extends the known range by 224 km north from the site described by Hodge (1973) in Alaska and 168 km north from the site described by Ferguson (1961) in British Columbia (Figure 1). The specimen was found 27 August 1974 at the bottom of a shallow, partially dug well. Three sheets of corrugated metal roofing material had been placed over the hole to prevent it from filling with debris. Several Bufo boreas (Baird and Girard) had been previously retrieved from the hole. The well was located 72 m from the Taku River and 27 m from a water-filled depression. The area which surrounded the weU had been cleared of underbrush. The mature trees and ground debris, however, were undisturbed. The area was shaded throughout the day and remained cool and damp. The specimen is an adult female. Standard measurements for the specimen are cm total length, cm snout-vent length, cm tail length, and cm vent length. The combined vomerine teeth count is 33 and each side has 13 costal grooves. The uninterrupted yellow-green dorsal stripe exhibits irregular borders without. â FERGUSON â² HODGE â ^MILLER Figure l.
