BARBOUR: NOTES ON THE HERPETOLOGY OF JAMAICA. 295 



specimen was seen after the ridge was crossed, and at Castleton Gardens on the 

 north side of this divide a careful search failed to reveal a single example. In the 

 material at hand are about a hundred or more examples taken within a mile of 

 the Constant Spring Hotel. They are equally abundant about the outskirts of 

 Spanish Town ; but at Mandeville not a single example was found. 



Anolis sagrae Bum. & Bibk. 

 Duraeril et Bibron, Erp. Gen., 1837, 4, p. 149. 



Apparently rare. There are three specimens in the United States National 

 Museum from Jamaica with no definite locality ; and one in the collection of the 

 M. C. Z., obtained from the U. S. Nat. Mus. in exchange. In my collection, or 

 in that made by Mr. A. E. Wight, not a single example occurs. In my note- 

 book I find record of catching wliat I took to be Anolis sagrae at Anotto Bay, 

 but the specimen is evidently lost. In coloration 1 do not believe that this 

 lizard can be distinguished from A. lineatopus, but the larger head shields, the 

 more even sized and more strongly keeled ventrals serve to separate specimens 

 in hand easily. A comparison of the four specimens with Cuban and Bahaman 

 specimens shows no difference between them. 



This lizard ranges through the Bahamas to Cuba, Jamaica, and part of 

 Central America also ; according to Boulenger, to Venezuela. 



Anolis iodurus Gosse. 

 Gosse, Ann. Mag. Nat. Hist., 1850, ser, 2, 6, p. 344. 



Dr. Stejneger, who has very kindly aided me in the study of these lizards, has 

 shown me that the species usually called A. grahamii Gray has been confounded 

 with A. iodurus. Gosse states that the ventral scales are smooth, while Gray states 

 that in his species the ventrals are keeled. This species is the vivid green species 

 with sky-blue tail which is found about Kingston and other localities in middle 

 Jamaica, as in Hope and Castleton Gardens, at Anotto Bay and about Spanish 

 Town and Bog Walk. The dewlap is very widely distensible and is a burnt 

 orange color with a deeper red center. It changes to brown or almost black, and 

 when it does so, faint vermiculations appear like those which so strongly mark 

 A. opalinus and the true A. grahamii. Usually, however, it is solid leaf green 

 and is, in life, very easily distinguishable from these other two species. In the 

 young there is often a wide white vertebral band, and this is sometimes visible 

 in examples about half grown. In three specimens from Mandeville there is a 

 strong tendency toward an imbrication of the smooth ventrals ; this is also 

 marked in some of the series of about tweuty from Kingston ; it is more or less 

 evident in all. 



Confined to Jamaica.
