BARBOUR: NOTES ON THE HERPETOLOGY OF JAMAICA. 293 



distance from latter to ear opening. Rostral large with a long median cleft. 

 Nostril between rostral, first supralabial, one small triangular postnasal, and a 

 moderate supranasal. The two supranasals and a small scale between them border 

 the rostral above posteriorly. Four large supralabials to beneath center of eye 

 Head and body covered with small, rather prominent, tubercle-like scales, larger 

 on snout. Mental large, like rostral, in contact with two scales posteriorly. Two 

 large and deep, one small and deep, and one small and narrow infralabials. Scales 

 on throat imbricate, small, rounded in outline, sometimes with a trace of a keel. 

 On the belly the scales are smooth with a more triangular outline. 



Ground color of upper surfaces grayish or slightly reddish, with scattered spots 

 of dusky gray. Some of these are of considerable size, much larger than in 

 S. punctatissimus Dum. et Bibr., or in S. nigropimctatus Gray. Posterior to the 

 sacral region is a spectacle-like marking similar to that often seeu in S. I'meolatus 

 Lichtenstein var. B. Bouleuger (Cat. Liz. Brit. Mus., 1885, 1, p. 222).

We did not succeed in securing a specimen of the Iguana. It is reported to be 

 still extant in the range of highlands known as the Heathshire Hills, but to be 

 very rare. It is absent from the rest of the main island. Dr. M. Grabham, the 

 well-informed naturalist of Kingston, to whom I am indebted for many valuable 

 notes, tells me that a small colony still exists on Goat Island. This is a good-sized 

 piece of laud, whither happily the mongoose has not been carried and where 

 probably the last of the iguanas and boas will be found. Goat Island lies in 

 Portland Bight, off the south coast of Jamaica, not far from Old Harbor and the 

 mouth of Salt River. 



Until some one studies material from all the islands on which iguanas occur, so 

 that the exact identity and distribution of each species can be made out, it is im- 

 possible even to conjecture the range of all the species. This one, to judge from 

 descriptions only, seems to be confined to Jamaica.

This lizard, which is commonly known to the natives as " the white croaking 

 lizard with red gills," is everywhere very uncommon. Three specimens were 

 taken at Constant Springs, near Kingston, and one at the Castletou Botanical 

 Gardens. The species is known to the natives in the vicinity of Spanish Town 

 and Mandeville. From the latter locality Mr. Wight has recently sent in seven 

 fine examples. At Bath, and at other points in the eastern part of the island, as 

 well as at Port Antonio, it was not known to the natives, so far as I could find 

 out. There is a specimen in the collection of the Museum, No. 6232, from King- 

 ston. The life colors of this creature are rather attractive. It is gray or whitish
