separate p. 5) quotes Maynard to the effect that " The Iguana occurs 

 commonly in the chffs of both tliis island and Little Cayman." He 

 was discussing the island of Cayman Brae. During the autumn of 

 1915 this island was visited by the most terrific hurricane of historic 

 times. The whole terrestrial fauna of the island is said to have suffered 

 very seriously.

Diagnosis: — Nasals broadly in contact with the rostral. Pre- 

 frontal region covered by a pair of rectangular supranasals broadly 

 in contact in the middle line of the snout; each supranasal in contact 

 with a pair of narrow prefrontals which are followed by a very large 

 posterior prefrontal; the anterior and posterior prefrontals form a 

 median suture continuous with the nasal and supranasal suture, — 

 all of these scutes covering the upper surface of the snout strongly 

 convex, even tubercular. Frontal region between the prefrontals 

 and the supraorbital semicircles covered by several rows of large 

 irregular scales; the row in contact with the prefrontals consisting 

 of very large scales, the largest being about a third as large as the 

 posterior prefrontal; between the semicircles on a line with their 

 anterior end a single large flat scale. Supraorbital semicircles formed 

 of large tubercular scales clearly differentiated from the slightly 

 swollen scale of the supraorbital and frontal regions; semicircles 

 separated by two partly by four rows of scales. Occipital region 

 covered with scales slightly larger than the frontoparietals, the outer 

 rows much larger than the others; two rows of scales between the 

 occipital and the semicircles. Canthus rostralis consisting of a single 

 large canthal scale and a short squarish precanthal, both swollen and 

 slightly keeled; the canthal scale in contact with two elongate supra- 

 ciliaries. Dorsal crest formed of low blunt spines, the largest about 

 half a centimeter high; this crest broadly interrupted on the shoulders
