Lepidosis. Rostral. — Touches 6 shields, the rostro-nasal, and rostro- 

 internasal sutures subequal or the latter longest ; the portion visible 

 from above one half (or nearly) the distance from the end of the snout 

 to the frontal. Inter-nasals. — Two, the suture between them, equal to 

 or nearly one half the suture between the prefrontal fellows ; half or 

 less than half the internaso-praefrontal sutures. Prefrontals. — Two, 

 the suture between them half or less than half the praefronto-frontal 

 sutures ; in contact with internasal, posterior nasal, loreal, praeocular, 

 supraocular, and frontal*. Frontal. — Touches 6 shields, the supraocular 

 sutures rather the longest. Supraoculars. — Length subequal to frontal, 

 breadth about half that of the frontal. Parietah. — Touch one or 

 two postoculars. Nasals. — Divided ; in contact with the 1st and 2nd 

 supralabials. Loreal. — One, small, as long as high, little longer than 

 half the nasals (rarely confluent with prefrontal, Gunther). Prce- 

 oculars. — One. Postoculars. — Two (rarely three). Temporals. — One, 

 touching the 5th and 6th supralabials. Supralabials, — 7 (rarely 6 or 8), 

 the 3rd and 4th touching the eye (or 3rd only in rare examples o wing- 

 to a confluence ot two of the normal shields). Rarely the 6th shield 

 just tails lo reach the labial margin. Infralabials. — 4, (rarely 5), the 

 4th largest, and in contact with two scales behind. Sublinguals. — Two 

 pairs, the posterior about two-thirds the anterior, and in contact with 

 the 4th only of the infralabial series. Costals. — 15 in the whole body 

 length, the last row slightly enlarged ; no keels ; apical pits present, 

 and single. Ventrals. — Angulate. In Variety A. $ 158 ? to 184, 9 

 158 ? to 218. t In Variety B $ 358 to 169, 9 174 to 184. Anal — 

 Divided (rarely entire). Subcaudals. — Divided. In Variety A they 

 are 38 to 55 in $, 37 to 52 in 9 ; in Variety B 38 to 46 in $, 36 

 to 40 in 9 . 



Dentition (a) Maxillary. — The maxilla has an edentulous space 

 anteriorly which would accommodate about 3 teeth of the size of the 

 foremost of the series. It supports 6 or 7 very compressed teeth of 



* In one specimen of Variety B in our Society's collection these shields are completely 

 separated by the frontal. 



f The number of the ventrals varies somewhat according to locality. In the Oriental 

 Region ihey range between 158 ? ami 184 in $ , and 158 ? and 204 in 9, but in the Indus 

 and Trans-Indus tracts a $ has 18(3, and the range for 4 9 is 200 to 218.
