the supraorbital region, and another extends longitudinally back from the 

 rostral plate ; there is a light triangular area upon the posterior upper labials. 

 A dark shade upon the occiput. Posterior part of the femur pale ; digits 

 specked with lighter. In the female the colors are lighter and more varied ; 

 there are dark shades upon the dorsal region, and oftentimes on the sides of 

 the neck. 



Specimens (5737 J) in Mus. Smithsonian Inst., whence the Acad. Nat. Sci. 

 has obtained examples ; part of a very valuable collection made at Monte 

 Verde, Cuba, by Mr. Chas. Wright. 



This species represents the same form as A. cyanopleurus and argen- 

 t e o 1 u s, though in the nature of the scales it approaches slightly the L o y- 

 s i a n u s type. It is very easily recognized. 



Anolis (Gastrotropis) lemurin us Cope. 



Size small ; tail about twice the length of the head and body. Head short, 

 broad, front concave, eyes very large. Occipital plate small, elliptic, sepa- 

 rated from the granulations posterior to it by a single series of small plates, 

 and by two series from the superciliaries. The latter are in contact on the 

 medial frontal line, or separated by one row of very small scales. Facial rugae 

 obsolete ; one large scale bordering the first superciliary anteriorly, and sepa- 

 rated from those of the canthus rostralis by a few of nearly equal size ; the 

 remaining scales of the front and muzzle are small, (less upon the latter,) 

 polygonal, carinate. Nostrils subterminal. Canthus rostralis very short, 

 making an angle of 40 with the commissure of the mouth. Six loreal rows 

 of scales, six or seven superior labials, infralabials small, keeled. Palpe- 

 brals fifteen to twenty, more or less keeled, separated from the superciliaries 

 by small scales. A weak nuchal fold. Superior femoral and brachial scales 

 small. Inferior lateral scales smaller than dorsal, the latter, with the superior 

 lateral and ventral, keeled. Tail entirely cylindrical, covered with strongly 

 keeled scales. Anterior extremity reaching the groin ; posterior, extending 

 forward to the posterior, sometimes the anterior border of the orbit. Goitre 

 small. Total length 2 in. 10 lin. ; tail 2 in. 5 lin. 



Color leek-green tinged with brown anteriorly; muzzle brownish, a brown 

 band between the eyes. A crescentic brown band upon the occiput, angularly 

 bordered with black anteriorly, and having a median longitudinal black spot. 

 A similar small black spot upon the nape at the confluence of two oblique 

 pale brown bands, one from each orbit, often pale bordered interiorly ; the 

 pale border sometimes extending to near the groin as a narrow longitudinal 

 band. A third small black spot upon the interscapular region. Three or four 

 large brown spots upon the posterior part of the dorsal region. Sides and 

 labial region varied with brown ; extremities and digits obliquely banded with 

 the same. Belly immaculate, the reflections golden and green. 



Three male specimens in Mus. Academy from Veragua, New Grenada, sent 

 by Mr. R. W. Mitchell. A female specimen before us, from the same locality, 

 which resembles A. Sallei, as well as this species, has a broad, dark bor- 

 dered, ochraceous dorsal band, black bordered and partially embracing a pale 

 angular area upon the occiput ; a chevron-shaped brown band between the eyes ; 

 several dark lines radiating from the orbit ; sides and belly immaculate ; digits, 

 goitre and labial plates black spotted ; extremities immaculate, except a pale 

 mark on the nosterior face of the thigh. 



Anolis (Gastrotropis) argenteolus Cope. 



Size small, form elongate. Head elongate, acute ; facial ruga? obsolete, frontal 

 concavity shallow, short. Interorbital space very narrow, orbits large. Can- 

 thus rostralis but little prominent anteriorly; nostril lateral, subterminal. 

 Plates of the front not small, subhexagonal, smooth. Superciliary plates four 

 or five on each side, elongate, in close contact on the median frontal line, sepa- 

 rated from the small occipital. Superocular or palpebral disc more or less iso-
