single lamellae under the fourth toe and 14 under the fifth toe; tail 

 cylindrical, distinctly compressed toward the tip, which is reproduced. 



Dimensions: Head to posterior border of ear, 35 mm.; head and 

 body, 126 mm.; tail (reproduced), 167 mm. 



Color (in alcohol): Above drab-gray, with very indistinct darker 

 traces of six or seven transverse bars separating squarish areas of 

 distinctly lighter hue; tail with diminishing bars at base and longitud- 

 inal dark broken lines on reproduced portion; can thai region dark; a 

 wide dark stripe behind the eye, bordered above by a white stripe, 

 both fading out above the shoulder; limbs vermiculated above with 

 dark; entire lower surfaces immaculate light olive-buff. 



Variations. — A considerable difference is met with in the size of the 

 dorsal granules among the three specimens I have examined, as I 

 have counted from 36 to 45 granules in the standard distance. This 

 may be due to the bruising of the skin, for on all portions that have 

 received apparent injury the scales are much finer than on the rest of 

 the skin. The specimens have suffered many slight wounds in their 

 delicate skins, which have healed perfectly, the only trace of mis- 

 adventure being in the patches of tiny granules that break the more 

 or less symmetrical diagonal rows of larger granular scales. The 

 ventral scales show 17 to 20 scales in the standard distance from 

 center of eye to tip of snout. The lamellae on the fourth toe vary 

 from about 16 to about 20, their gradual blending proximally with 

 the other toe scales making it difficult to ascertain their precise 

 termination. Supralabials are eight or nine, and infralabials seven 

 or eight; here again their gradual diminution to a size approaching 

 the granular temporal scales makes it impossible to be sure of the 

 last two, at least. 



The color pattern is about the same in all specimens, although 

 No. 59092 seems to have a dozen pairs of round light spots down the 

 middle of the back, instead of a wide, more or less rectangular, light 

 area, as is the case in the described specimen, No. 62362. Unfor- 

 tunately, the Museum of Comparative Zoology specimen is badly 

 bleached. 



Relationships. — More material is needed before it will be possible to 

 discuss definitely the relationships of this Hispaniolan lizard and the 

 Jamaican form, Aristelliger praesignis. The size of the dorsal granules 

 is about the same. The number of labials and of lamellae varies so 

 much that nothing can be adduced from the data on so few specimens, 

 while the mandibular teeth seem to have the same arrangement in 

 both forms. The ventral scales appear to be slightly smaller in the 

 Jamaican form. The Hispaniolan lizard has 17 to 20 ventral scales 

 in the standard distance from center of eye to tip of snout in the tliree 

 specimens I have recorded; the Jamaican lizard likewise has 17 to 20 

 in the four unmutilated examples in our collection.
