NATURAL SCIENCES OF PHILADELPHIA. 209 



similar to it all in contact with the inferior labials. Goitre moderate. Length 

 of head and body 1 in. 9 lin., from shoulders to rent 1 in. 2 1., tail 2 in. 



Above brown, the head darker; nape and extremities faintly vermiculated; 

 tail indistinctly spotted laterally and superiorly. Some specimens with dark 

 shadings at the angle of the jaws, near the auricular openings, and on the 

 sides. Goitre, vent, inferior surfaces of femora and base of tail, light yellow. 



Habitat. New Providence Islands. Bahamas. 



This species appears to be quite distinct. It resembles in its proportions 

 the young of Xiphosurus cristatellus. Specimens have been obtained by 

 my friend Mr. H. C. Wood, Jr., and are in the Academy and Smithsonian Mu- 

 seums. 



Anolis striatulus Cope. 



Size small ; form elongate. Head rather elongate, depressed, much as in A. 

 alligator Dum. Blbr. Tail once and two-thirds the length of the body, 

 moderately compressed, weakly verticillate, irregularly serrate. No dorsal 

 dermal fold ; an imperfect fold upon the nape, where two or three rows of 

 scales appear to be a little larger than those upon the dorsal and lateral re- 

 gions of the body. Anterior femoral and antibrachial scales large, smooth, 

 similar to those of the belly. Superior humeral, antibrachial, femoral and 

 tibial similar to those of the back. Occipital shield separated from the super- 

 ciliaries by small scales ; the latter usually in contact medially, four or five in 

 number upon each side. Palpebral disc rather round in outline, composed of 

 nine smooth scales. Facial rugas weak, soon obsolete, covered by three scales 

 anterior to the last superciliary. The space between these as far as the end 

 of the muzzle, covered with small smooth scales. Rostral plate bordered by 

 five scales, the median one fitting into an emargination between two mucro- 

 nations. Nostrils lateral. Canthus rostralis slightly concave, very obtuse 

 anteriorly. Superior labials eight. Loreal rows five. Anterior half of inferior 

 labials in contact with an inferior series of plates, which are longer than broad, 

 the anterior smaller than the first inferior labial. Goitre rather large. Two or 

 three small plates behind the vent ; scales at the base of the tail smooth. Ex- 

 tended posterior extremity not reaching beyond the posterior border of orbit. 

 Total length 4 in. 7 lin. ; tail 2 in. 11 lin. ; head from shoulder 8 lin. 



From alcoholic specimens it appears that the color is greenish gray above, 

 with very numerous darker marblings. The head aad chin are darker. The 

 medial dorsal line is crossed by four deep brown spots bordered with white. 

 The anterior of these, on the interscapular region, is narrow and more trans- 

 verse. There is a fifth spot at the base of the tail. The latter is clouded with 

 brown superiorly, and the extremities are cross-barred with the same. Thighs 

 dark, varied posteriorly. Goitre red-orange, abdomen greenish, femora and 

 vent golden. 



The female (preserved in spirits) only differs in being smaller. 



The Academy's Museum possesses this species from Mr. R. Swift, and the 

 Smithsonian's from Mr. Ruse ; a specimen has also been loaned me by Mr. 

 Theodore Gill. They were all obtained in the Island of St. Thomas, W. I. 

 The name is a diminutive of stratus, saddled. 



Anolis a cut us Hallowell, Proc. Acad. Nat. Sci. Philada, 1856, 228. The 

 locality, " Cuba," assigned by Dr. Hallowell to this species with doubt, is pro- 

 bably incorrect. It has been recently sent from Santa Cruz, W. I., to the 

 Smithsonian Institute by Mr. A. H. Ruse, and is also in the Academy's Museum. 

 An excellent description of it has been recently published by Dr. A. Giinther, 

 in the Annals and Magazine of Natural History, 1859, p. 212, under the name 

 of Anolis Newtoni. The specimens described were from Santa Cruz. 



Anolis maculatus Gray, Catal. Liz. Brit. Mus. 203. The habitat not 

 indicated. Dr. Gray's description of this species leaves much to be desired. 

 Several of the numerous specimens of females before us so coincide with the 



1861.] 15
