Remarks on coloration . — The southernmost series of specimens, 
from Comptche, Mendocino County (nos. 28499-28506, Calif. Acad. 
Sci.), presents a pattern of fine yellow dots on the dorsal as well as 
the ventral surface, and the ‘marbled’ pattern seen in the more north- 
ern individuals is indicated chiefly along the sides of the body in the 
largest (oldest?) specimen. The mid-dorsal region in all specimens 
tends to be dark without light patterning. The variegated pattern 
extends to the end of the tail in northern specimens and the fine 
spotting is continued to the tip of the tail in the Comptche material.

Range. — This salamander is found in the coastal district of Cali- 
fornia from Comptche, Mendocino County (Van Denburgh, 1916, 
p. 216), north to the Oregon boundary. The California Academy 
of Sciences has specimens from Carlotta, Alton, Trinidad, and Orick, 
Humboldt County, and Requa, Del Norte County. In Oregon it has 
been taken at Fort Umpqua (Cope, 1869, pp. 109-110) and at Elmira, 
Lane County (Calif. Acad. Sci.). No specimens are known from 
Washington, but Yarrow (1883, p. 159) lists two from “Puget’s 
Sound, Oreg.,” not mentioned by Cope. It has been taken at Union 
Bay, Bayne Island, British Columbia (Calif. Acad. Sci.). All the 
localities of record are within 50 miles of the sea coast. 
Life-history . — Practically nothing is known of the habits of 
Aneides ferreus. Van Denburgh (loc. cit.) says that two specimens 
obtained at Requa, May 22-26, 1911, “were taken from the rotten 
wood of a dead tree in which they were living some 20 feet above the 
ground. ” This suggests that ferreus may be, like lugubris, of arboreal 
habitat. The former has the ends of the digits rather square-ended, 
as though tending toward development of expanded tips such as are 
seen in climbing amphibians like the Hylidae. Two specimens of 
ferreus were taken under slabs of redwood on the ground in a virgin
