feet. In Burma it is rather uncommon, Evans and I only obtain- 

 ing five out of some 600 odd snakes. Two of these were from 

 Prome, two from the Southern Shan States, and one from 

 S again g. 



Lepidosis — Rostral. — Touches 6 shields, the rostro nasal suture 

 being much longer than the rostro-internasals. Internasals. — A 

 pair, the suture between the fellows about two-thirds that between 

 the prefrontal fellows, and about two-thirds to nearly equal to the 

 internaso-prse frontal. Prcefrontals . — A pair, the suture between 

 them about one-third greater than the prgefronto-frontal ; in 

 contact with internasal, postnasal (or nasal), loreal, prasocular, 

 supraocular, and frontal. Frontal. — Touches 6 shields, the fronto- 

 supraocular suture three times the length of the fronto-parietals 

 and twice the fronto-prsefrontals. Supraoctdars. — Length subequal 

 to breadth; rather broader than frontal. Nasals. — Semi-divided or 

 divided, in contact with the 1st and 2nd supralabials. Loreal. — One, 

 about twice as long as high. Prceomlar. — One, not touching frontal. 

 Postoculars. — Two. Temporals. — One, touching one supralabial 

 only, normally the 6th. Supralabials. — Normally 8 with the 4th and 

 5th touching the eye, sometimes 9, the 5th and 6th touching the 

 eye. Infralabials . — 5 or 6, the last largest and in contact with 2 

 scales usually behind ; 4th and 5th, or 5th and 6th touching the 

 posterior sublinguals. Sublinguals. — Two subequal pairs. Costals. 

 — Two headslengths behind head 17, at midbody 17, two heads- 

 lengths before vent 13. The reduction from 17 to 15 is due to an 

 absorption of the 3rd row above the ventrals, that from 15 to 13 

 to the absorption of the 7th row, but both steps occurring very 

 closely together may be mixed or reversed ; apical facets single, 

 obscure; keels none. Ventrals. — 166 to 188 (156 Boulenger) 

 evenly rounded. Anal. — Divided. Subcaudals. — 71 to 92 (64 

 Jerdon), from 9 to 12 ventrals intervene between the navel and 

 anal shield. 



Anomalies. — I have once seen an inferior loreal wedged be- 

 tween the 2nd and 3rd labials, and once the two last ventrals were 

 divided like the anal. 



Dentition* — Maxillary. — In front 4 (rarely 3) small teeth, the
