1922] Schmidt, Amphibians and Reptiles of Lower California 673 



Van Denburgh lists this species as probably entering northeastern 

 Lower California but not yet definitely recorded from the peninsula. 

 It seems highly probable that the specimen recorded by Meek as C. 

 stejnegeri from San Felipe, on the Gulf side of the peninsula, should be 

 placed here. 



I have referred specimens in the Biological Survey collection from 

 Cocopah Mts., east base (U. S. N. M. Nos. 37693-4), San Felipe Bay 

 (37690), and Poso Altamirano (37696) to this subspecies. The specimen 

 from Poso Altamirano, near the center of the peninsula, differs slightly in 

 coloration and in having smaller antebrachials from the typical tessel- 

 latus. It seems best, however, to place it with this species, pending the 

 accumulation of further data.

The four specimens of this form brought back by the Albatross 

 Expedition are of considerable interest for the variations they exhibit. 

 In two specimens, the nasal is in contact with the second labial on one 

 side, separated from it on the other; in one case, just touching; in the 

 other, more broadly in contact. In two specimens, there are only two 

 complete rows of enlarged antebrachials; in the others, there are three 

 complete rows. In coloration, one specimen, No. 5522, from the more 

 southern locality, Abreojos Point, approaches C. rubidus in the distinct- 

 ness and wide separation of the black spots. The remaining three are 

 fully adult specimens, the spots somewhat smaller and less sharply 

 defined.
