THE HERPETOLOGY OF HISPANIOLA 171 



Republic, altitude 6,000 feet, collected in August 1938 by P. J. Dar- 

 lington. Head slightly more than one and one-half times as long as 

 broad, depressed, with broad low ridges on the snout on each side 

 of the concave frontal region; head scales polygonal, rather small, 

 more or less subequal, all unicarinate, nearly granular around the 

 occipital region; rostral more than twice as wide as high, slightly 

 narrower than the mentals; five scales bordering rostral between 

 supranasals; no regular paired series of scales on the anterior part of 

 the snout; supraorbital semicircles composed of scales not differing 

 greatly in size from the other snout scales, separated from each other 

 by three rows of scales, and from the occipital by three or four scales, 

 some of winch are almost granular; occipital about one-fourth the 

 area of the ear opening, inconspicuous, oval in shape, bordered by 

 scales which are nearly granular; supraocular disk composed of four 

 or five larger and seven or eight smaller keeled scales, separated

 granules. Paratype, U.S.N.M. No. 107566, from Loma Vieja, Cordillera Central,

from the supraorbital semicircles by one row of small scales, from the 

 superciliaries by two rows; can thus rostralis strongly projecting, 

 covered by five sharply keeled scales increasing in size posteriorly, 

 followed by one or two longer ones on the superciliary border; loreal 

 rows six; seven or eight scales in the subocular semicircle scarcely 

 enlarged, separated from supralabials by one row of scales; supra- 

 labials seven, the sixth coming below center of eye; temporal granules 

 about equal to the dorsals, with a double line of larger, flatter ones 

 forming the supratemporal line; back and sides covered with small, 

 heavily keeled granules, those of the midline not, or scarcely, differ- 

 entiated, about 50 granules along the dorsolateral region equaling 

 the distance between tip of snout and center of eye; ventral scales 

 about twice as large as the dorsal granules, smooth, imbricate, squar- 

 ish; throat covered with small keeled granules, which gradually are 

 replaced on the gular fan by small, smooth scales like those of the belly;
