logs may yield a few, but undoubtedly the best way to get series of 

 them would be to follow a plow over some field already somewhat 

 cultivated, as Dr. Barbour did to secure the Puerto Rican forms. 

 It may well be that they are lacking entirely in certain portions of 

 Hispaniola, while common enough in other parts, where conditions 

 of the soil may suit their special needs.

Description of a paratype. — U.S.N. M. No. 67113, a half-grown 

 specimen from Cap-Ha'itien, Haiti, collected in 1914 by W. M. Mann. 

 Rostral completely fused with the nasals, which are partially separated 

 on top of the snout by a median cleft less than one-half the length of 

 the suture between the long prefrontals; a short suture leading from 

 the lower border of the nostril backward to the first upper labial; 

 ocular rather small, unequally 4-sided, smaller than the postocular 

 or the third supralabial; a rather small temporal between the 

 postocular and the third supralabial, not (on left side) or barely (on 

 right) in contact with the ocular and somewhat smaller; eye plainly 

 visible through the ocular; frontals a little shorter than prefrontals 

 and not so broad; a pair of small, poorly differentiated occipitals in 

 contact behind the frontals; three supralabials, the second as long as 

 the other two together; three lower labials, the first very minute, the 

 second exceedingly large, the third quite small ; a moderate-sized malar 

 shield behind the second lower labial ; mental followed by a very large 

 median postmental somewhat longer than broad; just behind the 

 postmental and between the second infralabials are three scales (the 

 postgeneials) lying in a transverse row, the central one much the small- 

 est; 230 rings on the body and 20 on the tail; the dorsal segments of 

 each ring longer than broad; the 10 median ventral segments broader 

 than long, the inner two conspicuously so; 14 segments above the lat- 

 eral line and 16 below it; six anal shields; eight preanal pores. 



Dimensions: Total length (body somewhat mutilated) about 120
