636 EEPORT OF NATIONAL MUSEUM, 1902. 



slightly browner in the basal half or a little beyond the compressed 

 elevated portion, followed by a median uniform blackish portion and 

 a terminal part which is uniform pale brownish olive; feet nearly uni- 

 form dusky; dewlap very large, with thickened edge, the color of the 

 skin being a dull orange-olive, the distant scales straw yellow; iris 

 blackish brown; tongue plumbeous. 



No. 26900, adult male, same locality, February 26, very similar, 

 but the crossbars less well denned on the flanks. 



Another adult male (No. 26901), same locality and date, on the other 

 hand, was more deeply colored, the oblique strings of yellowish beads 

 across the velvet}^ black sides being very conspicuous. Eye deep 

 indigo blue. 



No. 26902, also an adult male caught at the same place and time, 

 was nearly uniform olive brown when captured, but the pattern came 

 out gradually and the body color became lighter while being held 

 alive in the hand; feet above black; chin back to the beginning of the 

 dewlap bright orange yellow, the dark marblings on the yellow being 

 Indian red. A prett} T high cervico-nuchal fold of rounded outline. 



A young specimen, No. 26904, same locality and date as No. 26903, 

 resembled the latter closely, though lateral crossbars and oblique 

 bands of yellow spots were obsolete; a pale vertebral band extends 

 from occiput to some distance on the tail, the black dorsal crossbars 

 being hourglass shaped; dewlap present, but small. 



Another young specimen (No. 26905) was uniformly velvety blackish 

 brown above. 



Numerous specimens collected at Adjuntas (1,450 feet altitude) during 

 the second week of April agree in color with those from El Yunque, 

 including the yellow chin, though they did not seem to be as dark 

 and velvety, the greater richness of the color in the latter locality 

 being probably due to the greater humidity. The narrow bands of 

 pale bead-like spots on the flanks, the yellow spot on the chin, and the 

 dark metallic blue of the "white" of the eyes may be regarded as 

 absolutely characteristic of this species. 



Habitat. — This species seems to be confined to the coffee belt and 

 the high mountain tops above it. In the western portion of the 

 island it probably goes farther down than at the eastern end, where 

 we found none at the Catalina coffee plantation, about 900 feet alti- 

 tude, though it is to be noted that the United States Fish Commission 

 party obtained a single specimen (No. 25723) on the slope of El 

 Yunque, somewhere between 600 and 900 feet above the sea. At 

 Utuado, in the west, it occurs, though apparently rare and not at the 

 level of the town. There is no record of the exact altitude at which 

 the types were collected, and the single specimen obtained by me dur- 

 ing a diligent search for nearly a week (No. 27180) was taken in a side 

 valley at least 100 feet higher than the town, consequently over 500 

 feet above sea level. At Adjuntas it was common in the coffee planta-
