History. — Batrachoseps attenuatus was discovered by Esehscholtz 
during his second visit to California in 1824 and a specimen collected 
by him was described in his Zoologischer Atlas. Esehscholtz’ meager 
description was supplemented by a six-page account of the anatomy 
of the species by Rathke. Cope in 1869 described material from Fort 
Tejon as Batrachoseps nigriventris. 
Range . — This species has been found at the north in southwestern 
Oregon (Stejneger and Barbour, 1917, p. 13), more definitely, Gold 
Beach and Harbor, Curry County (specimens in Calif. Acad. Sci.) ; 
in California it is present in the coastal region from Crescent City, 
Del Norte County (Calif. Acad. Sci.) south to San Diego (Calif. 
Acad. Sci.), extending inland to near Napa, Napa County, and to 
hills back of Livermore,” Alameda County (Mus. Vert. Zook). 
Specimens from Angel Island in San Francisco Bay are in the col- 
lection of the California Academy of Sciences. Dunn (1918, p. 439) 
has recorded this species from Sacramento ; but the record needs 
confirmation. In the Sierra Nevada it has been taken from Eldorado 
County southeast to 3 miles south of Nelson, Tulare County (Grinnell
