756 REPORT OF NATIONAL MUSEUM, 1898. 



The deutition of this species is neither distinctly diacranterian nor syncranteriau. 

 The maxillary is aimed with nine teeth, gradually becoming stronj;er, longer, and 

 more widely set behind; the last is conspicuously the longest, but scarcely more 

 distant from the penultimate than this is from the antepenultimate, although these 

 three teeth are much more distant than the others are from each other.

Ehadinaa ftilviviUls Cope, Journ. Acad. Nat. Sci. Phila., 1875, p. 139. 



Head small, iiot very distinct from body. Frontal a little longer 

 than the suture from it to the nasal, and a little shorter than common 

 suture of occipitals, two-thirds as wideas long. Kostral small, low ; post- 

 nasal higher than long; loreal as high as long. Superior labials eight, 

 seventh highest; temporals 1-1. Inferior labials ten, sixth largest, in 

 contact with middle of post geneials. Scales poreless. Gastrosteges 

 one huudredand seventy-seven; anal divided; urosteges ninety-one. 



Color above fulvous, below fulvous yellow. The three brown bauds 

 extend from the end of the nose to near the end of the tail; the lateral 

 involves the fourth and the half of each adjacent row of scales, and is 

 black edged; the dorsal is three and two half scales wide and is also 

 black edged. The brown is paler on top of the head and the ground 

 color is a narrow, yellow baud to the eye. Lips yellow, like the lower 

 surfaces, unspotted. 



This species is allied to the U. vittata Jan, with which Boulenger 

 unites it. The absence of the pseudopreocular, and the short loreal 

 plate, do not agree with the specimens of the latter.

The following description I have copied from Peters, as covering the 

 characters of the species thoroughly : 



Head and body elongate, the latter covered with 17 longitudinal rows of pitless 

 scales. Rostral much wider than high, scarcely reaching the superior surface of the
