is ill spirits. Gular region paler, uniform. Total length, 43 ram.; 

 length of body and head, 23 mm. 



This species is well distinguished by the form of the end of the 

 muzzle, and by the keeled ventral scales. The superciliary scales 

 are also entirely peculiar, as they present several free points upwards 

 and backwards, in place of the spine- like process found in the other 

 species. Port Antonio. 



Grand Cayman. 

 Trachycephalus septentrionalis Tsch. 

 Anolis grahamii conspersus Garman. 



"Very common on Grand Cayman, where they occur in great 

 numbers about the gardens and banana orchards." 



Liocephalus varius Garman. 



"Found only on Grand Cayman, where it is common among stones 

 by the roadside, and in stone walls. Habits similar to L. carinatus." 



Aristelliger praesignis Hallow. 



"Only one specimen taken on Grand Cayman. It clung so firmly 

 to the tree trunk on which it rested that much of the skin of the 

 bark was torn away in removing it. The habits of this gecko are 

 similar to those described for its allies ; while its sluggishness and 

 stupidity distinguish it sharply from the other lizards here described." 



Alsophis angulifer caymanus Garman. 



' ' This snake is very common on Grand Cayman, and I recall one 

 stone wall by the roadside that was fairly alive with them. On the 

 top stones many were lying warming in the sunshine, while from 

 crevices everywhere heads protruded. Their movements and general 

 actions resemble what is most familiar in our garter snakes."
