THE HERPETOLOGY OF HISPANIOLA 235 



pressed hind limb reaches to the anterior border of the ear. Digits 

 compressed, the fourth toe with 22 tricarinate lamellae. A relatively 

 rather low crest beginning at the occiput, becoming somewhat higher 

 and more conspicuous on the tail; the other caudal scales keeled and 

 mucronate; no verticils. The keels of the lateral and dorsal scales 

 are directed upward and backward so that the scale rows converge 

 strongly on the back. Tail only slightly compressed. A pah of 

 enlarged and elongate postanals in the male. 



Dimensions: Snout to vent, 75 mm.; head to posterior ear, 18 mm.; 

 tail (reproduced), 88 mm.; foreleg, 29 mm.; hindleg, 54 mm.; width 

 of head, 15 mm. 



Color: The color of one of the Beata Island lizards brought alive 

 by Dr. Wetmore to the National Zoological Park was as follows: 

 Above iridescent ochraceous to buff, the dorsal and lateral dark areas 

 olive to seal brown, the sides with occasional pale Nile blue spots on 

 the lateral scales. Top of head fawn color. Sides of head black and 

 white; throat pale drab; chest drab turning to ochre-yellow on the 

 center of the belly and becoming vinaceous-buff across posterior 

 abdomen and lower parts of tibiae and feet, with a darker ochraceous- 

 buff tone on the inferior femur. A mottling of ochraceous-rufous to 

 rufous on the posterior sides where the pale Nile blue spots on the 

 scales are in evidence. Tail uniform vinaceous-cinnamon above and 

 below. Hindlimbs the same above; forelimbs with a suffusion of 

 olive. Spots on head and neck black. 



In alcohol the ochraceous tones of the body turn to a plumbeous 

 tone. The spots on the throat and the dorsolateral striping show up 

 as clearly as they do on the living animal. 



Variations. — The paratype M.C.Z. No. 17737 has a medial series of 

 two scales on the snout, the anterior the larger, and well separated 

 from the rostral. The frontals and prefrontals are only partially sep- 

 arated from the canthals by a small elongate scale. There are about 

 40 scales around the middle of the body, while 52 dorsals may be 

 counted from the occiput to the base of the tail, and 13 dorsals are 

 contained in the distance between the occiput and the tip of the snout. 

 Shoulder folds are present but no lateral folds. The adpressed hind 

 limb barely reaches the posterior border of the eye. There are 22 

 keeled lamellae beneath the fourth toe. The dorsal crest is low but 

 distinct, and the caudal crest is a little higher. The distance from 

 snout to vent is 72 mm. ; the head is 20 mm. The other details of body 

 structure are essentially like those of the type specimen. 



Some of the adult males of this species, as well as of personatus per- 

 sonatus, have a swollen place just behind the nostrils on top of the 

 snout. This changes the profile of the head considerably, as in 

 U.S.N.M. No. 75910.
