THE HERPETOLOGY OF HISPANIOLA 305 



"Dimensions.— Snout to vent, 59 mm.; axilla to tip of longest 

 finger, 10.5 mm.; groin to tip of longest toe, 15 mm.; tip of snout to 

 ear opening, 8.5 mm. ; greatest breadth of head, 6 mm. 



"Variation. — Of the two paratypes, an adult male (A.M.N.H. No. 

 51766), measuring 56 mm. from snout to vent, is almost identical to 

 the type, having the same distinctive color pattern and short legs. 

 When its hindleg is pressed forward and its foreleg backward, the 

 distance between the appendages is approximately equal to the length 

 of the hind leg. The head-scales are essentially like those of the type, 

 but there is only one elongated subocular on each side. The other, 

 a young specimen (A.M.N.H. No. 51765), 27 mm. from snout to vent, 

 differs from the two adults in the series by having a stripe on either 

 side of the body in addition to the ten stripes of dark brown found in 

 the adults. There is also some indication of five other longitudinal 

 stripes of brown along the ventral surface of the belly. 



"In life the dark stripes were nearly black while the light ones were 

 lemon-yellow, changing into bluish at the tail-base. The tail was 

 blue and the whole color pattern greatly resembled that of Ameiva 

 lineolata Dumeril and Bibron. 



"Habitat. — The species is known only from the region of Monte 

 Cristy, Dominican Republic. The type was secured by a native 

 who said he found it under rubbish near the bank of the Rio Yaque del 

 Norte, not far from Monte Cristy. The other two specimens were 

 brought in by natives from the same region. They were mistaken 

 for Ameiva lineolata due to the remarkable resemblance in size and 

 color. Despite the fact that over 300 of the Ameiva were brought in 

 and the junior writer made a special search for them, no other speci- 

 mens of Mabuya were secured." 



A minor difference existing in the paratype, A.M.N.H. No. 51766, is 

 that its frontal plate is one and a half times the length of a fronto- 

 parietal; these scales are more nearly the same in the type. The 

 paratype likewise has two well-developed pairs of nuchals. Following 

 the nuchals there are about 61 dorsal scales to a point above the vent. 

 The fourth toe has 14 lamellae on its lower surface.
