426 F. Stoliczka — On Indian and Burmese Ophidians. [No. 4, 



The upper side is lighter, or darker, greyish, or olivaceous, brown, 

 the basal half, or two-fifths of each scale being darker than the 

 rest ; the lower side is either greyish, or almost purely, white ; 

 round the mouth, the tip of tail and in front of the anus generally 

 purely white, except in very young specimens, which are of a more 

 uniform coloration throughout. 



In addition to the synonyms of this species, quoted by Gunther, 

 Peters gives* Argyrophis truncatus, Gray, (from the Philippines) and 

 OnycTiocephalus capensis Smith (from ?), and considers it probable 

 that Tijphlops accedens, Jan, and T. pammeces of Gunther also belong 

 to it. As to the three first suggestions I cannot speak from experi- 

 ence, but the last named species of which I have examined a few 

 specimens! I am inclined to consider with Dr. Gunther provisionally 

 as distinct from hraminus. 



The specimens which appear to me referable to T. pammeces are 

 all of a nearly uniform pale brown color, while in true hraminus the 

 lower side is always conspicuously paler than the upper ; the 

 proportions of circumference in pammeces I found to vary between 

 /q- and 2^, indicating a decidedly thinner snake than hraminus ; the 

 structure of the headshields and the number of longitudinal rows 

 (20) of scales is in both the same, as stated by Gunther. 



Typhlops poeeectus, n. sp. PL xxv, figs. 1 — 4. 



Body very long, slender, of nearly equal thickness throughout, 

 neck somewhat contracted, but the head is again slightly broader 

 and depressed. Rostral broader above than in front, its width above 

 being about one-third of that of the head, the posterior margin is 

 slightly narrowly rounded. The nostrils are placed rather in front 

 than laterally. The nasal is divided from the fronto-nasal at the 

 lower side, but in front towards the rostral both are united. The 

 fronto-nasals extend posteriorly slightly beyond the rostral, but 

 do not meet each other. The nasal is in contact with the first and 

 second upper labial, the former being very small ; the fronto-nasal 

 touches only the 2nd labial. The prae-ocular and ocular are about

 two years ago near Calcutta.
