specimens, both male and female, of the latter species, is a median 

 longitudinal groove on the belly from behind the prseanal region, 

 the scales bordering the groove on each side being enlarged.

 The two specimens of this beautiful species obtained by Mr. 

 Buckley have already been described. 



21. Anolis bouvieri. 



Anolis bouvieri, Bocourt, Miss. Sc. Mex. iii. p. 58, pi. 14. fig. 8. 



Two specimens, apparently of this species, from Pallatanga and 

 Canelos. M. Bocourt's type was from Guatemala. Specimens 

 already identified by me in the British Museum as A. bouvieri are 

 from Pebas and from Guayaquil. The one from the latter locality 

 is that enumerated by Dr. Giinther as A. ceneus in his list of xMr. 

 Fraser's collection (P. Z. S. 1859, p. 89). A?iolis ceneus, Gray, 

 however, cannot be looked upon as a species, since the single speci- 

 men on which it appears to have been founded proves to be only a 

 young Anolis alligator, D. & B. See O'Shaughnessy, Ann. N. H.

22. Leiocephalus aculeatus. 



Leiocepalus aculeatus, O'Shaughnessy, Ann. N. H. ser. 5, vol. iv 

 p. 303 (1879). 



Four additional specimens from Canelos and Pallatanga afford me 

 the opportunity of giving some further particulars about this remark- 

 able species. On each side of the occiput are some erect scales, 

 forming a flag-like border. These curious scales, which are not 

 conical, are present in both sexes, and appear characteristic of the 

 species, as they are not seen in L. iridescens nor, of course, in the 

 species of the genus with small cephalic shields. 



The sexes are very distinct. The male is of much darker colora- 

 tion, as previously described, and has the whole gular region deep 

 black. It has also the tail covered with very large scales, and very 

 strongly compressed, almost resembling Basiliscus in this respect. 

 The female has the back light brown, with triangular bars of darker 

 pointing backwards. The sides below the lateral crest are dark 

 brown, sharply separated from the lighter hue of the back. The 

 tail is compressed at the root only, rounded afterwards. This spe- 

 cies would belong to the same section of Leiocephalus as L. hermi- 

 nieri, D. & B., which also has the ventral scales keeled. That
