from the anus ; scales upon the upper part of the thighs very slightly carinated, 

 some of them with a double carina; a pular fold. 



Coloration. Above bluish, with black maculae ; under parts lighter, with a 

 tinge of yellow and ferruginous; a black spot beneath each axilla. 



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

 to vent 1 inch 7 lines; of tail 2 inches 9 lines. Total length 4 inches. 



Habitat. Unknown. One specimen in Museum, belonging to the Green Col- 

 lection, presented by Dr. Bache. 



Gen. Remarks. This species differs from Carolinensis in the less prolonged 

 snout, the absence of the well-marked ridges upon it, the juxtaposition of the 

 supra-orbitar ridges, th** smooth ventral scales, and in its mode of coloration. 

 The specimen described by Dumeril and Bibron was found in Martinique. The 

 general resemblance of the head to that of Alligator i> quite striking. Accord- 

 ing to Dumeril and Bibron, who have given an excellent description of this 

 animal, the black markings under the axillae are constant, 



Anolis Carolinensis. 



We have twenty-eight specimens of Anolis Carolinensis from Cuba and the 

 southero portion of the United States. These evidently belong to the same spe- 

 cies ; the specimens differ more or less in color, some being of a beautiful bright 

 green with scarcely any spots, others more or less spotted and lined upon the 

 back, throat and under part of the tail ; nearly all have the dark-colored spot 

 upon the temple ; three or four of the specimens have a broad white band with 

 irrfgnlar edges upon the middle line of the back, constituting a well-marked 

 Yariety. 



Habits The following remarks in regard to the habits of these interesting 

 animals have been communicated to me by a friend in the South, who has had 

 ample opportunities of observing them carefully : 



1st. That the}' drink frequently. 



2d. That when they shed they uniformly swallow their exuvias. 



3d. That when they happen to break their caudal appendage it is renewed. 

 The growth of the tail, it appears, is more rapid after the broken ends have 

 united. I have myself had for a long time several of these beautiful creatures 

 alive, and they became so tame as whenever a drop of water was presented to 

 them upon the tip of the finger, to leave the part of the twig on which they hap- 

 pened to be and eagerly run up after it, protruding their tongues and lapping 

 very much after the manner of the dog. They change their color, frequently 

 being sometimes more or less brown, but are usually of a light and beautiful 

 pea green. Their favorite food appeared to be flies, which they devoured 

 greedily. 



Gen. BRACHYSAURUS, nob. 



Char. Head short, covered above with polygonal flattened plates of unequal 

 size; nostrils tubular, in a single plate, near its posterior margin; no distinct 

 occipital plate ; a row of broad hexagonal scales over each orbit ; a row of large 

 and smooth plates upon the side of the head ; no transverse folds upon the neck ; 

 scales upon back, sides and abdomen carinated ; the dorsal and middle row 

 larger than the others, tectiform ; no pores upon thighs or in front of anus. 



B. EUYTHROGASTER, nob. 



Description. The head is of moderate size, short and thick, rounded above, 

 longer than broad, covered above with polygonal scales of unequal size, uni- 

 carinate ; the rostral plate is broad and narrow, very slightly elevated ; imme- 

 diately behind it arc two triangular plates, with a larger one between them ; the 

 nostrils are circular, looking backward and upward, situated near the posterior 

 margin of a quadrangular plate ; the supra-orbitar ridge on each side is consti- 

 tuted by a row of polygonal scales of unequal size, seven in number, in contact 

 at their middle, there being no intermediate longitudinal row of scales ; between 

 the two posterior scales of the supra-orbitar ridges are two large quadrangular
