THE HERPETOLOGY OF HISPANIOLA 227 



tip of snout to a little above and behind the ear sepia, with two or 

 three pale cream spots on the upper lip, the last of these continuing 

 backwards to the ear and fading out as a light streak a little way 

 behind the ear; top of head olive; the rostral and internasals and nasals 

 sepia ; a sepia spot between the posterior prefrontals and an indistinct 

 marking of the same hue on the frontals and supraoculars. 



"Paratypes.—U. S. N. M. Nos. 74047-53, 74055-74, all from the 

 same place and collected on the same date as the type specimen. 



" Variations. — The species under consideration, like the others of its 

 group in Haiti, has two prefrontals. The medial series of scales on top 

 of the snout are most often three in number, although two, four and 

 even five are known to occur. Supraoculars are usually six, although 

 some individuals have but five. The dorsal scales counted from the 

 occiput to the beginning of the tail range from 57 to 66 in number, 

 while around the body there are from 41 to 49 uneven diagonal rows. 

 There are usually 14 or 15 dorsal scales in the distance from tip of 

 snout to occiput; exceptional specimens have 12 and 13 up to 17 scales 

 in that distance. The subdigital lamellae are from 20 to 24 in number, 

 with 23 occurring most often. 



"The proportion of the head and body to the length of the hind leg 

 is between 60% and 79% in the lizards above 50 mm. in length, the 

 average leg length being 72% of the head and body in eighteen cases. 

 The hind leg when adpressed very seldom reaches beyond the anterior 

 border of the ear, and most often falls considerably behind the ear, 

 while sometimes it just reaches the shoulder. In five lizards under 

 43 mm. in length the leg proportion averaged 75.4%. 



"While the coloration of L. p. scalaris strongly resembles that of 

 L. p. mentalis in a general way, yet the specific differences, in adult 

 males at least, are well marked. The latter subspecies has the very 

 dark patch on the side of the head ending sharply at the upper 

 border of the ear or a scale or two behind it, while there is no distinct 

 dark lateral stripe continuing backwards from it. In the former 

 subspecies the dark area on the side of the head is rather ill defined, 

 although behind the ear it may be seen to merge with the dark lateral 

 stripe, which remains more or less distinct in the adult. The heavily 

 mucronate body scales of scalaris give it a much more bristling aspect 

 than is the case with the much sleeker mentalis. Both species have a 

 similar pattern on the mental and labials, and the relation between 

 them seems to be rather close, although the short hindleg and more 

 mucronate scales of scalaris separate it readily from its ally. The 

 young, however, are practically indistinguishable."
