fig. 2; Strauch, J. c. p. 380. 
Premaxillary teeth 7; maxillaries 4—4; mandibulars 6—6. 
Snout rounded, prominent. Tail cylindrical, as thick as the body. 
Rostral moderate, triangular; nasals forming a short suture: a 
pair of large prefrontals followed by a pair of smaller frontals, the 
suture between the former being scarcely longer than that between 
the latter; occipitals small ; eye visible through the ocular ; a post- 
ocular, one or two infraoculars, a preocular; four upper labials, 
fourth smallest, first either in contact with the preefrontal, or sepa- 
rated by a small shield; mental trapezoid, followed by a seven- 
sided chin-shield ; three lower labials, second largest. Two hundred 
and forty to two hundred and fifty-three annuli on the body, and 
twenty-six to twenty-nine on the tail; the segments of the annuli 
longer than broad on the back-and sides, a little broader than long 
on the two median ventral rows; on the middle of the body, an 
annulus contains forty-six or forty-eight segments, twenty-two or

triangular; nasals forming a suture; a pair of preefrontals and a 
pair of frontals; occipitals small; eye hardly distinct; no pre- or 
infraocular ; three upper labials ; mental anvil-shaped, followed by 
a larger chin-shield, the posterior border of which forms an angle; 
three lower labials, posterior very small, second largest, forming a 
suture with achin-shield posteriorly. Two hundred and thirty-five 
to two hundred and thirty-eight annuli on the body, and twenty-six 
to twenty-eight on the tail; on the back and sides the segments of
