V. San Domingo, Drs. Brown, Fraser and Gabb. 



A few of the species of the collection made by Dr. Brown are from the 

 Island of Gonave, off the West Coast of Santo Domingo ; the others are from 

 near Port au Prince.

Scales in thirty -six longitudinal rows ; each with a strong median keel, 

 and seven or eight weaker ones on each side of it, making fifteen or seven- 

 teen in all. The median keels are strong and continuous from the nape, 

 becoming stronger posteriorly, especially on the tail, whose superior and 

 lateral surfaces are thus thrown into gutters. In the specimen the distal 

 part of the tail is lost. The keels form oblique lines over the sides ; they 

 are strong on the hinder and weaker on the anterior limbs. 



The general form is slender, and the limbs are quite weak ; the latter 

 when extended along the side fail to meet by the length of the posterior 

 foot and leg to the knee. The head is flat and rather elongate, and its 

 scuta are normal. There are nine superior labials, of which the eighth is 

 the first one angulated above. Both the loreals are rather higher than 

 long. Five supraorbitals, the posterior separated by two scales from the 

 parietal. Interparietal large as parietal ; a large post-interparietal. Five 

 pairs of large infralabials, which are separated from the labials by scales. 



Ground color gray; no longitudinal lines, but the nape and back are 

 crossed by seventeen brown cross-bars, which are nearly in contact me- 

 dially, and taper to disappearance on the upper part of the side. Their 

 dorsal portions are sometimes confluent longitudinally. A series of faint 

 dusted brown spots on the inferior part of the sides. Below, white, with 

 a few scales here and there brown. Limbs brown above. 



Length from end of muzzle to vent three and a half inches; from do. 

 to middle of auricular meatus five-eighths of an inch ; from do. to axilla 

 one and five-eighths inch. 



From Puerto Plata, Santo Domingo. Charles A. Fraser. No. 10260. 



This species is quite distinct from those previously known in both 

 squamation and color.
