7ieio Species ofAnolidse. 279 



Scales of muzzle either convex only or indistinctly keeled. 

 Supraorbitals separated on vertex by two rows of scales. 

 Occipital large, ovate, larger than the ear-opening, and half 

 tlie length of the eye. Polygonal scales of supraocular disk 

 numerous, convex or weakly keeled. Infraorbitals two rows. 

 Form elongate, slender. Hind limb reaching to or beyond ex- 

 tremity of muzzle. Several series of regular keeled scales on 

 middle of back, larger than the granules which cover the sides, 

 but smaller than the ventral scales, which are ovate and keeled. 

 Tail long, rounded, covered with scales like those of the belly. 



Digital expansions well developed. 



Colours : bronzed brown above ; an orbital transverse stripe ; 

 lower surface viridescent ; darker variegations on the back, 

 taking tlie form of oblique streaks on the sides, as in Dra- 

 conura chrt/solepis. 



Specimens in the British Museum from the island of 

 Grenada. 



Anolis tessellatuSj sp. n. 



Resembles A. transversalis. Head not quite twice as long 

 as broad, no frontal concavity ; covered •with large polygonal 

 flat scales ; the supraorbitals in contact ; the occipital large, 

 but separated from these by several scales ; the occipital region 

 bounded triangularly by feebly raised ridges. Ear-opening 

 small, round. Scales of back and sides polygonal or roundish, 

 smooth ; of belly larger, oval, imbricated, and keeled ; those 

 of the tail similar. 



Digital dilatations narrow. 



Colour : green, with brown markings on back and tail. 



Specimen in the British Museum, collected by Mr. Salvia 

 in Costa Eica. 



Anolis lentigmosuSj sp. n. 

 Head short, broad, obtuse, much shorter than tibia, its width 

 being two thirds of its length ; its height at the orbital region 

 nearly equal to its width. Scales of the front and muzzle 

 small, strongly tricarinate ; of occipital region very numerous, 

 polygonal, flat, the occipital itself being scarcely distinguishable 

 in their midst. Supraorbital borders composed of numerous 

 small-sized scales, separated by one or more scales on the 

 vertex, and elsewhere rapidly and widely divergent. Nearly 

 the whole of the supraocular space covered by about twenty 

 rather small keeled or rugose scales. Scales of middle dorsal 

 region larger than those of the sides, and increasing in size 

 gradually from the neck to the tail ; they arc striate, present- 

 ing where the epidermis is preserved the appearance of being 

 tricarinate; continuing on the tail they become distinctly
