rulate above. Digital expansions rather narrow. Abdominal scales smooth 

 rounded ; scales of the lateral thoracic region keeled. A strong nuchal der- 

 mal fold and a slight dorsal one. Lateral and dorsal scales minutely granular, 

 except two to four median series, which are larger and keeled. Anterior 

 brachial, antebrachial and tibial, and inferior tibial scales keeled. Angular 

 process of mandibulum prominent. Temporo-occipital region swollen ; occiput 

 with a median, gemmiform, sharply-defined depression, which is continuous 

 with the gutter-like frontal concavity. The facial rugae are well defined, 

 little divergent, including rather a deep longitudinal depression. Nostrils 

 large, lateral ; canthus rostralis sharp, a little curved, depressed anteriorly. 

 Superciliary plates large, five on each side, in contact or barely separated 

 medially. Frontal scales rather large, longitudinal, smooth. Occipital plate 

 elongate, small, separated from superciliaries. Seven or eight loreal rows ; 

 seven superior labials ; symphyseals large, first infralabial not large. Tym- 

 panic orifice large. Anterior extremity extended, reaches beyond the groin ; 

 the posterior anterior to the orbit. Length of head to angle of jaw 9 lines ; 

 from angle of mandible to vent 1 in. 8 lin.; hind extremity 2 in. 2 lin. 



General color green, with blackish tints. Posterior extremities sometimes 

 cross-banded. Female with a pale vertebral streak. 



Habitat. Western Hayti ; from near Jeremie, Dr. Weinland. Mus. Compar. 

 Zoology, Cambridge, No. 1501. 



Anolis (Coccocssus) pentaprion. 



Size medium ; form stout. Tail one and a quarter times the length of the 

 head and body, much compressed, subtriangular in section, the vertebral 

 angle trenchant, serrate ; four basal angles formed by the continued keels of 

 as many series of large scales. Goitre large. Scales of the back and sides 

 equal, minute, the abdominal larger, though small, subgraniform, smooth. 

 Orbits large, auricular orifice small. Head stout, muzzle thick, rounded. 

 Canthus rostralis obtuse anteriorly, facial rugae just traceable posteriorly. 

 Nares near the end of the muzzle, lateral. Occiput covered with numerous 

 irregular smooth plates, which extend between the superciliary series. Plates 

 of the front and muzzle rather small, polygonal, rough, not keeled ; palpe- 

 brals numerous, smooth, three loreal rows ; nine superior labials, nine inferior, 

 the second small. Infralabials small. Extremities stout, their scales small, 

 not keeled ; digital expansions well developed. The anterior extremity does 

 not reach the groin, the posterior scarcely the auricular orifice. Length of 

 head and body 2 in. 61.; of tail 3 in. 4 1.; head to ear 8 1. ; hinder extremity 1 in. 2 1. 



Above whitish, tinted with reddish brown, and marbled with brown. Ex- 

 tremities and tail pale reddish brown with brown cross-bars. Frontal and 

 occipital regions dark, muzzle pale ; some brown shades beneath the eye on 

 both jaws. Beneath yellowish ; goitre cherry red. 



Habitat. New Granada, near the river Truando. Discovered by Arthur 

 Schott, Esq., who accompanied the U. S. Expedition under Lieut. Michler. 



The shape of the tail and the subgranular ventral scales place this species 

 in a section of the genus which I call Coccoessus. It is most nearly 

 allied to sect. Gastrotropis, Fitz., in which A. schiedii Wieg. resembles 

 it in many respects ; the form of the muzzle is much as in this species and in 

 A. nebu lo sus.* 



Anolis (Dracontura) 1 i m i f r o n s. 



Tail cylindrical, without a larger median series of scales. Ventral scales 

 smooth. Dorsal and lateral scales granular, rugulose, all equal. Scales of 

 arm, inferior tibia and anterior femur keeled. Neck rather elongate ; eyes 

 large, head broad, very concave in profile, muzzle prominent, truncate, nearly 



* Dr. Gray, Catal. Liz. Brit. Mus., refers A. sag rae to this species. They are differ- 

 ent, and typical of different sections of the genus.
