THE HERPETOLOGY OF HISPANIOLA 183 



Variations. — Since the original description appeared, I have come 

 upon only six additional specimens. In all the females the color 

 pattern is very faint, being darkest in M.C.Z. No. 13794, the largest, 

 where the white lateral line is very distinct to halfway between axilla and 

 groin. The color of the male from Fonds-des-Negres is similar to that 

 of the type. In two of the females from Port-au-Prince there are two 

 rows of scales separating the supraorbital semicircles; in the other four 

 specimens there is a single row. There are five to seven loreal rows, 

 while 3 or 4 scales separate the supraorbital semicircles from the 

 occipital. The male from Fonds-des-Negres has 35 lamellae under 

 the fourth toe, 21 of which fall under the second and third phalanges, 

 just as in the type specimen. The same weak development of the gular 

 fan is likewise noticeable in No. 72629. So far as I can judge from the 

 known specimens, the species is very constant in its characters. 



Remarks. — A. hendersoni has a close ally in A. bahorucoensis, as 

 they are both distinguished by the same elongated head and body. 

 Although at first glance the immaculate dorsum of hendersoni does 

 not suggest an alliance with the heavily banded bahorucoensis, other 

 details of coloration are much more suggestive of the relationship. 

 The hps are spotted in a nearly identical manner. The white lateral 

 line, so striking a feature of hendersoni, is developed in a slighter 

 degree in bahorucoensis. The peculiarly crowded appearance of the 

 scales just behind the mentals, and their extreme convexity which 

 make them appear to be ridged without actually being keeled, is dupli- 

 cated exactly in both species. Their differences are equally distinct, 

 and set them off in very much the same way that chloro-cyanus and 

 coelestinus are differentiated. The very fine body granules of bahoru- 

 coensis and its rather square snout are not to be confused with the 

 coarser body scales and more rounded profile of hendersoni. 



While Anolis hendersoni has a superficial resemblance in body build 

 and color to A. pulchellus, a careful comparison reveals little real 

 simiilarity in details of scalation. The heavy gular fold and the un- 

 paired median snout scales of pulchellus are not characteristic of the 

 Hispaniolan lizard. 



The types of the Cuban Anolis alutaceus have been compared with 

 hendersoni, and there is a similarity in the shape of the head and in the 

 bodily proportions. A. alutaceus, however, has a heavier gular fold, 

 wider and smoother canthal scales, no paired median snout scales, a 

 less concave loreal region, a different color pattern, and is distinctly 

 smaller in size, in all of which respects it differs from hendersoni.
