 Table 32. — Specimens of Anolis hendersoni examined 



The presence of transverse throat folds in hendersoni leads me to 

 compare it with both species of Deiroptyx from Cuba, but it does not 

 appear to be like them in any other characters. 



Specimens examined. — As listed in table 32.

Original description. — "Diagnostic Characters. — This species 

 is not closely allied to any other Anolis in Hispaniola. It differs 

 from other slender-bodied Anolis of the Island in being heavier and 

 having a less well-defined band of enlarged scales in the mid-dorsal 

 line of the back. It also differs from these in its smooth ventral scales 

 and in the absence of a dewlap. The very marked sexual dichroma- 

 tism of the species is another of its distinctive features. 



"Detailed Description.— Type: A.M.N.H. No. 51128, adult 

 male. Collected in the Valley of Polo, Barahona Province, D. R., 

 September 14-19, 1932, by W. G. Hassler. 



"Habitus slender, body compressed, head elongate with sharp 

 can thus rostralis; greatest diameter of the eyes contained three and 

 one-third times in the distance from tip of snout to eye-slit; distance 

 across the head immediately anterior to the orbits contained twice in 

 the distance between the tip of snout and center of eye; frontal ridges 

 very weak, diverging anterior to the eye and then slightly converging 

 to end immediately behind and medial to the nostril on either side; 

 frontal region slightly concave between these ridges; scales on the 

 upper surface of the head anterior to the orbits smooth, scales on the 

 supraorbital semicircles and of the supraorbital discs keeled. Rostral 

 low, about two and one-half times as wide as high; ventral margin of 

 subnasal scale in contact with rostral, nostrils separated from the 

 rostral by a prenasal scale which is larger than the nostril; prenasals
