Jeremie, Hayti, Dr. D. F. Weinland ; Navassa, Prof. 

 S. F. Baud. 



In the memoirs of the Mus. Comp. Zool., VIII, 1883 

 (Kept, and Batr. N. Araer., Introd., p. xiii) the writer 

 called attention to the peculiar specialized corneous dig- 

 <yinir combs on the third and fourth toes of the hind foot 

 of this lizard. Since that time this apparatus has l^een 

 found by Professor Cope to mark the species of Cyclura, 

 also of burrowing habits, and to aflbrd a most important 

 character in distinguishing them from the species of Cten- 

 osaura. 



Iguana tuberculata Law., 1768. 



Trinidad, C. S. Cazabon ; Saba, F. Lagois ; St. Thom- 

 as, S. Garman ; Grenada, P. Gellinau. 



The Grenada specimens are intermediate between /. 

 tuberculata and /. rhinoloj)ha. They have one prominent 

 series of tubercles on the neck, and several scattered 

 ones above the hinder extremity of the series. The tu- 

 bercles on the snout are not so prominent as in /. rhin- 

 olopha from Central America, but the arrangement is the 

 same. The tubercles on the neck are comparatively few 

 as compared with those on Nicaraguan types.
