Description. Costals. — 2 heads lengths from head 23 (21 in one), 

 in midbody 23, 2 heads lengths before the vent 19. The reduction 

 of rows from 23 to 21 and from 21 to 19 is due to the absorption 

 of the 3rd row above the ventrals into the 2nd or 4th, both steps 

 occurring very close together. Vertebrals not enlarged. Ultimate 

 row enlarged, more than twice the breadth of the median costals. 

 Keels. — Very obtuse in the basal half of some median rows 

 posteriorly. Ventrals in No. 1, 197 ; in No. 2, 180. Anal divided. 

 Subcaudals.— In No. 1, 41, the 1st and 2nd entire. In No. 2, 

 47, the 1st to 10th and last entire, the rest- divide. Rostral. 

 — Touches 6 shields, the rostro-internasal sutures as long as the 

 rostro-nasal and rostro-labial taken together. Portion visible above 

 equals its distance to the frontal. Intemasals— The suture between 

 the fellows three-quarters that between the prefrontal fellows ; 

 about half the inter naso -prefrontal sutures. Prefrontals,. — 

 The suture between the fellows equal to the prsefronto-fronta 1
