THE AMERICAN NATURALIST [Vol. XLIH 



torosus, has long been known. I have found it commonly in 

 a number of canons of the San Gabriel range and heard of it in 

 other parts of southern California ; in some places it seems to be 

 quite abundant. 



Two years ago last spring, just after the winter rains were 

 over, a salamander was brought into the laboratory. It had 

 been found in a garden near an orange orchard in Claremont, 

 CaL, about four miles from permanent flowing water of the 

 mountains and several hundred feet above subterranean water; 

 the only water that could come to it was from rains and from 

 irrigation. It was a full-grown specimen of Batrachoceps 

 attenuatus. Some weeks later in the early part of June another 

 full-grown specimen was brought in from another locality near 

 Claremont. This time it was from a large, dry, uncultivated 

 area and was found under a stone. A few hundred feet from 

 the place where it was found there was a deep well. I after- 

 ward learned that ten or more years earlier a pond of consider- 

 able extent had covered this place. 



During the winter of 1906-7 two small salamanders were sent 

 to me from San Diego. They were half -grown B. attenuatus. 

 The identification of these four specimens extends the known 

 range of this species some hundreds of miles. 



In May of this year a number of other salamanders were ob- 

 tained from well up in the mountains north of Claremont, a 

 number of specimens of B. attenuatus and two full-grown speci- 

 mens of Autodax lugubris. The specimens of Autodax were 

 found in a narrow crevice in a high rocky wall. This sort of a 

 location is quite different from the other places where Autodax 

 has been found. 



Judging from the character of the land and water of Lower 

 California it seems quite probable that one or all of the species 

 mentioned in this note may occur farther south than San Diego.
