pressed, with a low crest. End of muzzle to ear l // IV"; ear to vent 3''; vent 

 to end of tail 1" 5'". Anterior extremity 1 // f>tf /f . Posterior to heel 1" 6'";

Above dark brown, nape, vertebral line, and about five broad transverse 

 cross bars on each side darker, the space between tinged with yellowish. 

 Below bright yellow, gular region greyish, with some faint longitudinal 

 brown lines ; chin, labial and rostral shields yellow, or tinged with it. Ex- 

 tremities dark, with a few very faint cross bars.

** Tail cylindrical, or with vertebral and lateral scales equal ; ventrals keeled. 

 Anolis c ar n e u s. 



Scales everywhere flat and smaller than frontal. Head short, broad, espe- 

 cially occiput. Front narrow, concave, superciliary rows separated by two 

 or three rows of scales. Superciliaries nine or ten, not wider than long, not 

 continued as a large row on facial ridges, which are high, rounded, enclosing 

 deep concavity, which is filled with equal subhexagonal scales, smooth or 

 slightly one-keeled. Canthus rostralis sharp, short, descending steeply ; nos- 

 trils lateral, eight or ten rows of narrow scales between. Occipital small, sur- 

 rounded by nearly equal scales, which a little exceed the smooth dorsal. Eye 

 large ; eight loreal rows. Many rows of keeled infralabials, scarcely larger 

 than gulars. No whorls among tail scales, which are very weakly keeled. 

 Ear nearly as large as eye slit. Supraorbitals weakly keeled, in five rows, 

 not forming an isolated disc. From ear to end of muzzle 3| times from latter 

 point to vent, in an old specimen, four times in a young $. No dermal 

 dorsal fold. 9" b'" from muzzle to vent; tail 16"; groin to heel 5 r/ ; hind foot 

 3" 5 /// ; anterior limb 4" all from 9 j which is light yellowish brown above ; 

 a pink shaded median dorsal band, on each side of which is a narrow brown 

 band, which commence by two convergent portions on occiput, and are inter- 

 rupted behind opposite axilla; two or three other more or less interrupted 

 paler brown streaks on each side. Brown band between eyes. Beneath im- 

 maculate. Young <-^ everywhere rose colored, with some blackish markings 

 on posterior part of sides, and faint bands across hind and fore limbs. Goitre 

 very small. 



Two specimens in Mus. Britt. Lower Vera Paz Forest. Obtained from 

 Osbert Salvin, a thorough explorer of that region. 



A. s e m i 1 ineatu s. 



Near to cyanopleurus; agreeing in most points in squamation ; but 

 instead of six or seven there are 10 12 rows of larger dorsals ; 2 3 larger 

 smooth infralabials ; front scales broad as long, smooth, six rows from can- 

 thus row to canthus row at halfway to nares. A triangular patch of scales 

 as large as loreals behind the eye, which are abruptly surrounded by the 

 minute lateral. 



A brown shade from lores to middle of side ; yellow band from suprala- 

 bial line to middle of side or groin, which is bounded above and below by a 

 dark shade. Size, that of cyanopleurus. 



Hab. Hayti. Mus. Brit. 



Anolis bitectu s. 



Muzzle acuminate, with scales broad as long, 1 3 keeled, those between 

 ridge rows much smaller, minute, yet flat, one row between the double rowed 

 superciliaries. Occiput oval, surrounded by small scales. Two rows of ra- 

 ther broad keeled supraorbitals. Ear J of eye ; seven loreal rows ; canthus 

 rostralis short, nearly straight. Infra-maxillary small, equal, keeled. Minute 

 scales from eye along side ; nine larger dorsal rows, then two median size 

 each side, then lateral. About eighteen rows of ventrals. Male with well 

 developed goitre. Tail rather short. From end of muzzle to ear 1" 3 V/ ; to 

 vent 5" 2"'; hind foot 2"; heel to groin 2" V".
