HERPETOLOGY OF PORTO RICO. (Ul 



ing.s, Init with a pale baud along the middle of the })ack. It is lig-ured 

 (figs. 1)5-97). 



Colors of Thing animal.— Adxit male, U.S.N.M. No. 2(hS03 (L. S. 

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

 dark brown; edge of eyelids light yellowish: general color al)oye 

 bronzy greenish gray; head and seyeral faint longitudinal in-egular 

 spots on the sides of the back more bi'ownish; on each side of the 

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

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

 brownish l)lack and a light line outside the dark margin: on the middle 

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

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

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

 verging into l)ro\vnish orange toward the edge. 



A youiKjrr inah' (No. 208O5, same locality and date) was similai- })ut 

 darker, and with no definite markings of brown; tail cross -l)anded, 

 light and dusky; dewlap fairly well developed. 



An advJt female (No. 2(3801:, same locality and date) resem])led the 

 male, only browner, especially the supraorl)ital disk, which was almost 

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

 each side; throat whitish with gray marl)lings; abdomen greenish 

 yellow; no dewlap. 



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

 vidually, 1)ut 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 dral) without 

 distinct markings. The specimens obtained in Vieques had the dewlap 

 more brightly colored, thus in No. 27o6S (L. 8. No. 9053) it was green 

 very l)roadly margined with brownish orange in strong contrast. 



Ilahitat. — Aiaillx eristatella-s occurs not only in Porto Rico, Culel)ra, 

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

 recorded by lieinhardt and Liu'tken from St. Thomas, St. flohn. Just 

 van D3^ck, Water Island, and St. Croix. On Mona it is represented by 

 a nearly allied form. 



In Porto Rico it is proba)>ly the commonest species, being found 

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

 on the mountain sides as 1,4:1:0 feet. The highest point where I met 

 with this species was at Adjuntas, in which localit}", however, AnoUs 

 gundlacid was the commoner species. The few specimens of A. eris- 

 tateUxts seen there were found on rocks near the river and in the tow^n 

 itself, but not in the woods and coffee plantations.
