HERPETOLOGY OF LOWER CALIFORNIA.

is separated from the labials by two longitudinally placed 

 temporals. There are seven superior labials (the third 

 and fourth entering the orbit) and six infralabials (the 

 first pair in contact on the middle line). The anal plate 

 is divided. 



There is little variation in color. A specimen from 

 San Jose del Cabo may be described thus: The top of 

 the head, the temporal regions, and the first five trans- 

 verse rows of scales on the neck are brown, changing 

 gradually from hair brown, on the snout, to deep clove 

 brown posteriorly. On the sixth and seventh rows of 

 scales of the neck is a whitish collar about as wide as the 

 length of one scale. The rest of the upper surface is 

 bright broccoli brown, slightly vinaceous on the tail. The 

 posterior three -fourths of the ventral surface are tinged 

 with coral red, brightest immediately in front of the anus. 

 The anterior fourth of the ventral surface is pale grayish 

 clay color, but may have been red in life, as this color 

 has entirely disappeared from all parts of the belly in 

 other specimens. 



The specimens mentioned in the following table are all 

 from San Jose del Cabo except the first, which was se- 

 cured in the Sierra de la Laguna.
