new Species of GeckotidaB. 263 



(Pr. Ac. Nat. Sc. Phil. 1863, p. 102), also from California, 

 has " small ventral scales, which, although hexagonal, affect 

 a circular form/' They are in more than 25 longitudinal 

 series ; and if counted longitudinally from the vent to the 

 throat, where they gradually merge into the smaller gular 

 scales, the number is about sixty. The large campanuliform 

 mental is followed by two large postmentals, and these by a 

 series of much smaller roundish plates, set transversely, two 

 or three of them being behind each postmental, but not going 

 up laterally between the postmental and the second infra- 

 labial. 



This species has now been obtained from Guatemala and 

 Salvador. 



Phylhdactylus ventralis, sp. n. 



Differs from the above in the ventral scales, which are much 

 larger and regularly oval ; there are not more than fifteen or 

 sixteen longitudinal series of them ; and counted longitudinally, 

 to where they give place to the minute gular scales, they number 

 about forty -five. The mental shield is longer, narrower, and 

 more pointed posteriorly, its point being enclosed by two 

 postmentals ; and behind these a space reaching to about the 

 middle of the chin exhibits rounded or polygonal scales, much 

 larger than the minute gular scales of P. tuberculosus and 

 those which follow in this species reaching as far as the chest. 

 Immediately behind the postmentals the anterior rounded or 

 polygonal scales constitute a distinct larger transverse series 

 composed of four, the outermost on each side going up between 

 the postmental and the second infralabial, occupying an inter- 

 stice which is almost granular in P. tuberculosus. Head also 

 much narrower, more pointed, and less flattened than in that 

 srjecies. The dorsal tubercles are in fifteen longitudinal 

 series. The tail has rings of tuberculous scales at intervals, 

 and a broadened inferior central series of scales. Ear -opening 

 narrow, oblique. 



Ground-colour yellowish brown. A narrow distinct stripe 

 of dark brown from the nasal plate, through the eye, to the 

 side of the body • the back variegated with dark brown. 



Hab. Jamaica. One specimen, 4 inches in length. 



Tarentola ejihippiata, sp. n. 



Head broad, depressed; muzzle rounded, covered with 

 moderate-sized convex scales, somewhat larger in front than 

 on the hinder portions of the head. Back minutely granular, 

 with flat oval tubercles, disposed in fourteen regular longitu- 

 dinal series ; ventral surface covered with small uniform,
