The present specimens all agree in having " pseudo- 

 preoculars," flat heads, and dark postocular stripes cover- 

 ing less than half of the sixth supralabial plates — the 

 characters said to distinguish H. ochrorhyncha from H. 

 texana Stejneger, and H. chlorophcea Cope. 



The total length of the largest specimen is 525 mm. 



This species was originally described from specimens 

 collected by Mr. Xantus at Cape San Lucas. Mr. Belding 

 obtained others at La Paz, in 1882. It is not confined to 

 Lower California.
