Diagnosis, — Head one and three-fourth times to twice as long as 

 broad ; anterior supraocular very small, mostly indicated by a minute 

 granule ; enlarged dorsals in eight longitudinal series, the two median 

 ones smaller; ventrals in six series, smooth or very feebly keeled; 

 four pairs of chin shields ; two inguinal pores on each side ; nasals in 

 contact behind rostral ; tail two and one-half times to three times the 

 length of head and body. 



Description of type specimen. — Adult female : Rostral separated 

 from internasal by anterior nasals which are broadly in contact; 

 posterior loreal much larger than anterior; internasal as long as 

 j)refrontals which are about two-thirds the length of the frontal; 

 two large supraoculars, the anterior barely separated from the pos- 

 terior loreal by a granule which represents the first supraocular; 

 fourth supraocular very small, smaller than occipital; four super- 

 ciliaries, two anterior ones in contact with large anterior supraocular,

the two posterior ones separated from the second large supraocular 

 by a series of minute granules; frontal hexagonal, with a median 

 ridge, and much wider anteriorly than posteriorly; fronto-parietals 

 in contact with posterior large supraocular (third) but separated 

 from fourth by a granule; parietals large, considerably longer than 

 frontal; four supralabials in front of the subocular labial which is 

 largest and as long as third and fourth together; temporals small, 

 almost granular, keeled, about 10 in a row between postocular and the 

 elongate scales bordering the ear-opening anteriorly ; a series of four 

 elongate narrow scales along the outer edge of the parietals; four 

 pairs of chin shields, increasing in size posteriori}^, first pair in con- 

 tact throughout, second only in anterior half; eight dorsal rows of 

 keeled scales, the two median series small and irregular, on the pos- 

 terior half of the back reduced to a single row ; keels of large dorsals 

 forming continuous ridges, four of the large dorsals corresponding to 

 about four and one-half ventral plates; sides covered with minute
