108 BARBOUR — A NEW IGUANA [ Vol'.^lif ' 



Director of the Colorado Museum of Natural History in Denver. 

 It is well worth while noting that the iguana was found abun- 

 dant on the Cay, no less than nineteen being taken in an hour 

 or so. This fact now being established, they will probably be- 

 fore long go the way of their allies, which have nearly all been 

 exterminated by the meat-hungry natives. 



Cyclura figginsi sp. nov. 



Type, M. C. Z. no. 17,745, from Bitter Guana Cay, near Great Guana 

 Cay, Exuma Group, Bahama Islands, collected by A. M. Bailey. Para- 

 types in the Colorado Museum of Natural History, Denver, and in the 

 Museum of Comparative Zoology, Cambridge. 



A large species allied to Cyclura inornate, Barbour and Noble from U 

 Cay, Allen's Harbor, north of Highborn Cay, Exuma Group, Bahamas,' 

 and differing conspicuously in having tiny supranasals usually separated 

 by a small azygous scale and two pairs of praefrontals, the posterior pair 

 being invariably enormously enlarged. In this character the species is ap- 

 proached by no other in the genus. 



Description. — Nasals broadly in contact with the rostral and with 

 each other. Praefrontal region covered with a pair of small supranasals, 

 separated by a small scale, followed by two pairs of praefrontals, the pos- 

 terior pair being enormously enlarged, both pairs broadly in contact on the 

 median line of the snout. Frontal region covered with two rows of en- 

 1 arged scales, either three or four in a row, and these rows separated by a 

 series of lesser shields from a single enlarged boss which may represent the 

 frontal scale itself and which shows a slight tendency toward becoming a 

 'horn'; no evident supraorbital semicircles, this region being covered with 

 small irregular scales; frontal shield separated from the occipital, which is 

 of about the same size, by four (five or six) series of scales larger than those 

 on the supraorbital regions. Postnasal rather large; one large and one 

 small canthal. The contour of the other head shield may be seen by ex- 

 amining carefully the figure (Plates I and II). The enlarged scales on the 

 upper temporal and masseteric regions are characteristic and constant. 

 Dorsal crest of low blunt spines, enlarged on the lumbar region (6 mm. 

 =*= high) and on the base of the tail (9-10 mm. * high). The nuchal 

 crest very low, and widely separated from the dorsal. Four series of scales 

 between the limiting rows of each segment of the tail, each one slightly 

 larger than the one anterior to it.
