HERPETOLOGY OF PORTO RICO. 641 



rags, but with a pale band along the middle of the back. It i.s figured 



(figs. 5)5-1)7). 



Colors of living anwial. Adult male, U.S.N.M. No. 20803 (L. S. 

 No. 9011); Pueblo Viejo, near San Juan, February 14, 1901. Iris 

 dark brown; edge of eyelids light yellowish; general color above 

 bronzy greenish gray; head and several faint longitudinal irregular 

 spots on the sides of the back more brownish; on each side of the 

 median dorsal line between the insertion of the hind legs a better 

 defined and larger spot of irregular outline, pale brownish edged with 

 brownish black and a light line outside the dark margin; on the middle 

 line of the tail a series of dusky spots located at the base of the largest 

 spines; throat whitish; rest of underside suffused with greenish yel- 

 low, most intensely in the preanal region; dewlap greenish yellow 

 verging into brownish orange toward the edge. 



A younger malt (No. 20805, same locality and date) was similar but 

 darker, and with no definite markings of brown; tail cross -banded, 

 light and dusky; dewlap fairly well developed. 



An adult female (No. 20801, same locality and date) resembled the 

 male, only browner, especially the supraorbital disk, which was almost 

 ferruginous; median dorsal line paler grayish with a dusk} T shade on 

 each side; throat whitish with gray marblings; abdomen greenish 

 yellow; no dewlap. 



The coloration of the living specimens not only varies greatly indi- 

 vidually, but to some extent also locally. Thus, as a rule, the speci- 

 mens which we saw in Utuado were much more distinctly marked, 

 the dark dorsal cross bands standing out in much greater contrast than 

 in other localities. On the other hand, those collected in the white 

 limestone hills east of Ponce were nearly uniformly drab without 

 distinct markings. The specimens obtained in Vieques had the dewlap 

 more brightly colored, thus in No. 27008 (L. S. No. 9053) it was green 

 very broadly margined with brownish orange in strong contrast. 



Habitat. — An»I!s rristatellus occurs not only in Porto Rico, Culebra, 

 and Vieques; but also on all the Virgin Islands, specimens having been 

 recorded by lleinhardt and Luetken from St. Thomas, St. John, Just 

 van Dyck, Water Island, and St. Croix. On Mona it is represented by 

 a nearly allied form. 



In Porto Rico it is probably the commonest species, being found 

 everywhere in the lowlands and in certain localities at least as high up 

 on the mountain sides as 1,440 feet. The highest point where I met 

 with this species was at Adjuntas, in which locality, however, Anolis 

 gundlachiwBS the commoner species. The few specimens of A. cris- 

 tiitrlJiis seen there were found on rocks near the river and in the town 

 itself, but not in the woods and coffee plantations.
