The plates above the snout are broad and flattened ; the 

 combs appear on both third and fourth toes ; teeth serra- 

 ted. 



Cyclura cornuta, Daudin sp. 



Metqpocerus comutus Wagl. 



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

 S. F. Baird. 



In the memoirs of the Mus. Com p. Zool., VIII, 1883 

 (Rept. and Batr. N. Amer., Introd., p. xiii) the writer 

 called attention to the peculiar specialized corneous dig- 

 ging combs on the third and fourth toes of the hind foot 

 of this lizard. Since that time this apparatus has been 

 found by Professor Cope to mark the species of Cyclura, 

 also of burrowing habits, and to afford a most important 

 character in distinguishing them from the species of Cten- 

 osaura . 



Iguana tuberculata Lain-., 1768. 



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

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



The Grenada specimens are intermediate between /. 

 tuberculata and I. vliinolopha. They have one prominent 

 series of tubercles on the neck, and several scattered 

 ones above the hinder extremity ot 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. 



Iguana delicatlssima Law., 1768. 



Nevis and St. Barts, F. Lagois. 



The eggs of these specimens are elongate, about one 

 and seven-eighths inches by one and one-eighth.
