THE HERPETOLOGY OF HISPANIOLA 123 



cate; no enlarged scales in the midline; ten scales on the side of 

 the body between the front and hindlegs contained in the distance 

 between the tip of snout and center of eye. Mental a little longer 

 than broad, about twice as long as the rostral; three enlarged infra- 

 labials, the first approximately twice as long as the second; the second 

 twice as long as the third; the scales in a broad band across the throat 

 and along the sides of the abdomen keeled; those in the middle of the 

 abdomen smooth; scales on the abdomen two or three times as large 

 as those on the throat. A broad band of scales on the upper surface 

 of the fore limbs covered with keeled imbricated scales on both upper 

 and lower arm, the remaining scales small and tubercular; a similar 

 band of enlarged scales on the entire length of the hindlegs keeled 

 and imbricated like the dorsals, but these scales greatly diminishing 

 in size on the lower leg; scales on the posterior part of the thighs small 

 and tubercular; scales on the ventral surface of the hind limb keeled 

 like those on the sides of the abdomen and decreasing in size distally 

 on the leg; a patch of hypertrophied preanal scales forming a triangular 

 patch anterior to the cloaca. Dorsal scales on the regenerated tail 

 keeled like the body scales and on the anterior part of the tail a trifle 

 smaller than these; scales on the ventral surface of the tail smooth; 

 scales forming the ventral midline of the regenerated portion very broad. 



"Ground tone (in alcohol) a pale grayish-brown, slightly redder 

 on the tail and head; a series of conspicuous dark brown spots on 

 the entire upper surface; these spots on the upper surface of the head 

 few and of about the same size as the pupil, increasing in number 

 on the occiput, becoming numerous on the body where they average 

 about one-half the size of those on the neck; the dark spots tend to 

 arrange themselves in rows on the posterior body region and are 

 transferred into a dark streak in the inguinal region; another streak 

 of dark brown on the posterior surface of each thigh extending back 

 along the side of the tail for only a short distance (due to the regen- 

 erated tail). Ventral surfaces grayish or straw-color spotted with 

 dark brown on the throat and sides of the body, irregularly streaked 

 with the same tone on the chest and abdomen. 



"Dimensions. — Head and body, 26.5 mm.; tail (regenerated), 26 

 mm.; snout to posterior edge of ear, 6.5 mm.; snout to center of eye, 

 3.5 mm.; width of head, 5 mm.; fore limb from axilla, 7 mm.; hind 

 limb from groin, 9.5 mm. 



" Variation. — An adult female is usually more streaked than a 

 male, and exhibits a 'mask' in the scapular region. This mask is 

 formed by a large blotch of dark brown surrounding a pair of white 

 spots. Some adult females are nearly identical in color pattern to 

 adult males but the spots are smaller and tend to streak more. The 

 spotting on the head tends to streak, and in the immature of both 

 sexes as well as in adult females these streaks form a conspicuous
