heel spurs, and one frontal plate. The tibial shields in three rows, the 

 outer much larger, and outer toe longer than inner. It differs from tliat 

 species in having the prebrachial shield small, and in three sub-equal 

 longitudinal rows, graduating into the large prebachials regularly, inliav- 

 ing ten or eight regular marginal anal plates, the median pairs not ab- 

 ruptly larger, and in not having a series of black spots on the sides. The 

 teeth are from the nostril posteriorly 9 canine like, and seven or eight 

 obutuse molars, two or three posterior usually with a lateral cusp. Two 

 median plates in front of the anals. Gular scales in a transverse band of 

 about nine rows, larger ; relatively larger also than in A. plei, also the 

 latter has several rows of scales between the labials and infralabials ; the 

 A. a n a 1 i f e r a but one row. 



Greenish yellow below, brownish olive above, with blackish cross- 

 shades on the nape in St. Martin's specimens. Sides, groin and tail 

 above white spotted ; some white spots in rows across the rump.

Twenty-four transverse series of scales between interscapular region 

 and rump. Seven longitudinal series at the latter point, ten at the former. 

 Lateral scales large, nearly equalling the ventral, which are considerably 

 smaller than the dorsal. All well keeled and mucronate, except the ven- 

 tral, which are smooth and without mucro or emargination, except a few 

 spinous series in front of the vent. Gular scales entire. Palms and soles 

 strongly keeled ; tail slender, its scales strongly keeled like those of the 

 back. Male with three, female with six femoral pores. No granular 

 space in front of shoulder, and no longitudinal folds in the same region, 

 but a short vertical fold in which the skin is so deeply inverted as to
