Range. — This distinct species was first described from specimens 
taken at Sierra Madre and Pasadena, Los Angeles County (Camp, 
1915, pp. 327-330). One example was collected at Riverside, River- 
side County, about April 15, 1918 (no. 6736, Mus, Vert. Zool.) and 
two were taken in Orange County, exact locality unknown, in the 
spring of 1915 (nos, 9139-40, Mus, Vert. Zool.). The Pasadena 
specimens were taken beneath boards in a yard and in a cellar. At 
Sierra Madre the animals have been found under a broken cement 
slab, beneath wet lumber, and in post holes ; in August, two were taken 
several feet beneath the surface of the ground in loose gravel in a 
ravine bottom (Camp, loc. cit.). 
Life-history. — Practically nothing is known of the life-history of 
this species. Camp (loc. cit.) states that the localities of capture “lie 
in the upper edge of the Lower Sonoran life-zone (mesa oak associa- 
tion) and below the range of Batrachoseps attenuatus. The latter 
species appears to inhabit the Upper Sonoran zone. . . . Both species 
are entirely terrestrial and both appear to aestivate during the drier 
months, being then seldom found above ground. ’ *
