wis] Camp: New Amphibia from Southern California 329 



fore and hind limbs do not meet when pressed to sides of body; 

 digits rudimentary, four on both front and hind feet ; nostrils sep- 

 arated by nearly twice their distance from the orbits, not terminal, 

 connected with upper lip by thick-edged grooves; gular fold not 

 plainly marked ; body divided into eighteen folds, or segments, between 

 the front and hind limbs; skin very smooth and shiny; openings of 

 small pores barely visible on head region. Color in alcohol (from 

 Ridgway's Color Standards, 1912) light neutral gray above; sides, 

 lower parts, upper lip, palms and soles near eream buff; slightly 

 darker on under surface of tail and on ventral surface of body 

 transversely between limbs. 



Variations. — In the series of twenty-five specimens at hand the 

 costal folds number 17 in four, 18 in seventeen, and 19 in three. In 

 one specimen there are 17 folds on one side and 18 on the other side 

 of the body. In one specimen the outside (fourth) digit of the left 

 front foot is lacking. 



Distribution. — This large, light-colored Batrachoseps has been 

 taken on south Euclid Avenue beneath boards in a yard, and also in 

 a cellar, in Pasadena, California. The type was found in the neigh- 

 boring town of Sierra Madre under a broken piece of cement side- 

 walk, and others taken in the same vicinity were captured in piles 

 of clamp lumber and in post-holes. Two were taken in August, 

 1905, several feet beneath the surface of the ground in loose gravel 

 in a ravine bottom. The localities of capture lie in the upper edge 

 of the Lower Sonoran life-zone (mesa oak association) and below the 

 range of Batrachoseps atienuatus. The latter species appears to 

 inhabit the Upper Sonoran zone (maple-sycamore association) in 

 the mountain canons, possibly getting out into the valleys occasionally 

 along water courses. Both species are entirely terrestrial and both 

 appear to estivate during the drier months, being then seldom found 

 above ground.
