 the eye and is continued as a black band to the axil. The lower 

 parts are whitish, the tail dotted with greyish. 

 A single adult female is in the collection.

7. Proctoporus pachyurus, Tschudi. 



8. Enyalius laticeps, Guichen. 



A large adult specimen, probably a male ; differs from the other 

 smaller ones by having a series of larger scales along the side of the 

 back, by having a distinct black collar, and a yellowish longitudinal 

 band from the tympanum to the shoulder. 



9. Anolis fraseri, n. sp. 



Diagnosis. — Snout moderately elongate and depressed, with a 

 distinct canthus rostralis, and with a pair of obtuse ridges arising 

 from the bony superciliary margins ; a slight groove between those 

 two ridges ; the upper surface of the snout and the space between 

 the orbits are covered with innumerable very small shields. Loreal 

 region nearly flat, with five series of small shields. Occipital shield 

 none, or scarcely distinguishable from the others. All the scales 

 exceedingly small, those of the abdomen rather larger and keeled. 

 Neck without any crest ; trunk with a very slight serrated ridge, 

 perceptible in large individuals only; tail not crested. Pouch of 

 the throat well developed. Tail not compressed, not verticillated, 

 with the scales keeled and small. Greyish- or brownish-olive ; back 

 and tail with indistinct broad brown cross-bands. 



Description. — The snout is moderately depressed and slightly 

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

 three-quarters of the distance between the orbit and the extremity 

 of the snout ; anteriorly it is rounded. The canthus rostralis ii dis- 

 tinct, but not very sharp, and there is another pair of low convergent 

 ridges, arising from the superciliary margin of the bony orbit and 

 extending a little beyond the middle of the snout ; there is a shallow 

 groove between those ridges, but the space between the ridges and 

 the canthus rostralis is rather flat. 



The species is distinguished (especially from A. sagrce and nebu- 

 losus) by the exceedingly small shields of the upper parts of its head ;
