edge of gular fan not thickened posteriorly; limbs covered anteriorly 

 by imbricate, keeled scales, posteriorly by granules; upper surfaces of 

 hands and feet covered by small keeled scales; digital expansions 

 narrow, about 24 lamellae under the fourth toe; tail long, nearly two 

 and one-half times the length of head and body, slightly compressed, 

 not definitely verticillate, the upper median scale row larger and more 

 heavily keeled but not serrate iu profile; scales beneath the tail larger 

 and strongly keeled; postanal scales of male well developed; a faint 

 nuchal fold.

 posterior ear, 13 mm.; snout to center of eye, 8 mm.; width of head, 

 8 mm.; foreleg, 19 m.; hindleg, 41 mm. 



Color (in alcohol): Ground color of upper surfaces sepia, with fine 

 mottlings of clove brown all over the body tending to form about five 

 irregular, dark-edged, light-centered saddles, extending over the 

 back and narrowing on the sides; tail also with irregular dark and light 

 patches; head sepia with minute darker dots; belly cinereous; throat

Paratypes.—M.C.Z. No. 44361, an adult female, and U.S.N. M. No. 

 107556, a young male from the same locality as the type; M.C.Z. No. 

 44362 and U.S.N.M. No. 107557, from Loma Rucilla and mountains 

 north, at 4,000 to 7,000 feet, collected in June 1938; M.C.Z. No. 44364 

 from Valle Nuevo in the Cordillera Central southeast of Constanza, 

 taken at 6,000 to 8,000 feet in August 1938; M.C.Z. No. 44363, from 

 Constanza at 3,000 to 4,000 feet in August 1938, all by P. J. Darling-

Variations. — The six paratypes vary slightly as follows: Inter- 

 nasals bordering the rostral four or five, those directly between the 

 nasals six to eight, irregularly arranged; loreal "rows" six to nine, also 

 very irregular, especially the uppermost, and not always arranged in 

 rows even toward the labials; supraorbital semicircles separated from 

 each other by two or three rows of smaller scales, and from the occipital 

 by three to five uneven scales; four to seven supralabials to center of 

 eye, the total number being six to eight, of which the last one or two 

 may be very small; infralabials six or seven; malar rows four to six, 

 composed of fairly regular scales; lamellae under free part of fourth 

 toe 23 to 27; tail not verticillate distally, but sometimes a pair of very 

 indistinct verticils separated by five or six rows of irregular scales 

 may be made out proximally . The largest male is the type ; the largest 

 female, M.C.Z. No. 44361, measures 44 mm. in head and body length. 

 This female has a dorsal pattern of four saddlelike brown blotches, 

 with two smaller ones on the neck and some on the tail. The other 

 three females have a dorsal light stripe flanked by two brown stripes,
