DESCRIPTION OF A NEW SPECIES OF ANOLIS FROM CENTRAL 

 AMERICA. BY DR. A. GUNTHER, FOREIGN MEMB. ZOOL. 

 Soc. 



The following new species of Anolis was discovered by M. Salle 

 in Central America, and is now in the Collection of the British 

 Museum. 



ANOLIS SALL^EI, n. sp. 



Diagnosis. Snout moderately elongate and rather depressed, with 

 the canthus rostralis sharp, and with a pair of obtuse ridges, arising 

 from the bony superciliary margins and divergent anteriorly ; a 

 slight groove between these two ridges ; the upper surface of the 

 head is covered with small shields ; occipital shield present. Loreal 

 region slightly concave, with four series of small shields. Scales of 

 the back, belly, and tail distinct, imbricate, strongly keeled ; those 

 of the sides very small ; no trace of a crest ; tail rounded, not verti- 

 cillated ; gular pouch small. Greyish or brownish, with a more or 

 less distinct yellowish vertebral band ; sides and belly sometimes 

 with fine blackish longitudinal lines. 



Description. The snout is moderately depressed and slightly 

 elongate, the distance between the anterior angles of the orbits being 

 a little less only than that between the orbit and the extremity of 

 the snout. The canthus rostralis is distinct and, near the orbit, 

 rather sharp. There is another pair of low ridges, arising from the 

 bony superciliary margin and divergent anteriorly, with a slight 

 groove between ; they extend to the middle of the length of the 

 snout. The shields of the upper surface of the head are small, 

 arranged in irregular transverse series, about seven in the series 

 between the angles of the orbit ; the shields along the bony super- 

 ciliary margin are rather larger, but both series are separated from each 

 other by smaller shields. An occipital shield is distinct. The nostril 

 opens laterally, and is situated immediately behind the extremity 

 of the snout. The labial shields are exceedingly narrow, eight or 

 ten in number ; three or four series of smaller shields run parallel 

 to that of the lower labials, the remainder of the throat being covered 

 with very small polygonal scales. The pouch of the throat is very 

 little developed. The tympanum is very small. The temple and 

 the neck are granular. 



No crest whatever is visible, but the scales of the back are very 

 distinct, imbricate, keeled ; those of the sides are one-half smaller 

 and smooth ; those of the belly rhombic and distinctly keeled, rather 

 larger than the dorsal ones. The tail is rounded, not verticillated 

 or crested, covered with rhombic, imbricate, strongly keeled scales, 

 the keels forming longitudinal ridges. The fore-leg does not reach 

 to the loin, if laid backwards ; it is covered with rhombic keeled
