Habitat. Jamaica, Three specimens, two adult and one young presented by 

 Dr. Betton, 



Gen. Remarks. This species, although it might, with some propriety, be named 

 punctatus, from the great number of small white spots with which it is covered, 

 differs entirely in appearance from the punctatus of Daudiu, of which we have 

 one specimen from Surinam. The head in punctatus is much longer, the neck 

 more contracted and the body and tail longer. The scales on the front of the 

 head are smooth in punctatus, carinated in punctatissimus, and their shape and 

 general arrangement are very different; the row of plates above the supra-labials 

 are larger in the former species ; the scales upon the flanks are oblong in punc- 

 tatus, those upon the back flattened ; the tail is altogether difi'erent ; it is sub- 

 round in punctatus, with smooth scales, without verticillse, and the much larger 

 row of scales along the median line. The one is an inhabitant of Jamaica the 

 other of Surinam and Brazil. 



Anolis leucocephaltjs, nob. 



Char. Of larger size than usual among the smaller species of Anolis ; head 

 much depressed in front, covered with large and smooth polygonal scales ; 

 scales of supra orbitar ridge in contact at the middle ; temples covered with 

 polygonal scales ; upon sides suboval, smooth, larger than those upon back and 

 abdomen, interspaces filled with small granules; abdominal scales smooth; no 

 dorsal crest ; tail compressed cyclo-tetragonal at base ; color whitish with 

 blotches of green. 



Description. Head long and narrow, depressed in front, where it is covered 

 with large and smooth scales, much larger than in most other species of Anolis ; 

 scales upon the snout on the contrary very small ; nostrils small, suboval, their 

 anterior margin a line from the extremity of the snout, situated on the side of a 

 slight prominence, just within the ridge extending from the anterior margin of 

 the orbit to below the nostril and terminating at its anterior border ; the supra- 

 orbitar ridge is composed of four or live large scales ; they are in contact at their 

 middle, but not anteriorly or posteriorly ; the supra-orbitar ridge is not prolonged 

 anteriorly, the front, as before stated, being covered with smooth and large scales; 

 differing more or less in shape; ten or eleven quadrilateral plates may be 

 counted upon the margin of the upper jaw, 44 teeth in the lower, the ten an- 

 terior on each side pointed, the 12 posterior tricuspid ; 36 in the upper, eighteen 

 on each side, the ten anterior pointed, the rest tricuspid ; tongue slender, deeply 

 notched posteriorly, entire in front, three rows of smooth scales upon the side 

 of the head, between the supra-orbitar plates and the anterior orbitar ridge ; 

 temples covered with smooth polygonal scales, the .ntperior and posterior roics the largest; 

 auricular openings of moderate size, suboval, not denticulated ; scales upon the 

 sides suboval, smooth, separated from each other, the interspaces /died with small 

 granides ; these lateral scales are larger than those upon the back and abdomen; 

 those upon the neck and back are more closely united ; subround or polygonal ; 

 those upon the abdomen for the most part quadrangular, perfectly smooth ; no 

 crest upon the back or neck ; a large goitre extending from the chin as far as the 

 abdomen ; a veiy large portion of its surface w]\en distended appears to be desti- 

 tute of scales ; the scales upon the under part of the thighs and in front of 

 the arms, as well as upon the under part of the anterior extremities are quite 

 small, having the appearance of granulations ; those along the superior margin 

 of the thighs are quite large. Extremities slender; tail cyclo-tetragonal at base, 

 compressed in the rest of its extent; longer than head, neck and body, slightly 

 denticulated above, verticillate, seven distinct vertical rows of scales larger 

 than the rest; four or five rows upon the under part of the tail strongly cari- 

 nated. 



Coloration. General color whitish, with blotches of green ; abdomen white, 

 with a shade of green ; throat yellowish white ; in another and smaller specimen 

 the white is more pure and the blotches brown. 



Dimensions. Length of head 8 lines ; greatest breadth 5 lines ; length of body
