Dorsal scales striated, not keeled. Rostral not quite so wide as the 

 genial. Interfroutouasal large, irregularly jientagonal. Frontal louger 

 than wide. Frontoparietals present. Nasal scute in contact with the 

 rostral. Two postnasals superposed. Two or three loreals, the anterior 

 often obliquely divided. A i)reocular. A snbocular. Maxillary teeth 

 with trilobate crowns. Trunk encircled with thirty-two to thirty-eight 

 longitudinal series of scales, averaging thirty-six at the middle of the 

 body. This species, like Diploglossus Mlohatus, has the limbs well 

 developed. It differs from that species in many particulars, especially 

 in the shape of the cephalic plates. 



Length of head from the end of the muzzle to the posterior border of 

 the occipital jdate equals about twelve dorsal scales, and is one-seventh 

 of the distance between the chin and the cloaca. The second pair of 

 supranasals (or prefrontonasals) are large and directed obliquely out- 

 ward. The interfrou to nasal is wider than it is long and articulates 

 with the posterior concave border of the frontal. Frontal relatively 

 long, narrower in front than behind. Five supraoculars, of which the 

 second is wide in front and is in contact along that side with the inter- 

 froutouasal. The nasal, somewhat lengthened, is pierced posteriorly. 

 Postnasals small, quadrilateral, and superposed. Of the three loreals, 

 the middle one, when present, is the largest, and is pushed upward on 

 the muzzle, extending above the canthus rostralis and rarely reaching 

 the labials. Postloreal square, followed by a small median preocular. 

 Finally, the subocular represents a very long rectangle. The supra- 

 labials, ten on each side, of which the seventh and eighth, not so deep 

 as the others, support the subocular scute; the ninth is small and pen- 

 tagonal; the tenth, still smaller but similar in outline, is succeeded by 

 scutella similar to those on the cheek, which extend to the ear. Eight 

 pairs of inferior labials. Rostral not quite so large as the genial. The
