DRYOCALAMUS TRISTRIGATUS.* 
A small specimen of this rare snake from the Malay Archipelago. 
TROPIDONOTUS KHASIENSIS.* 
A specimen, probably from Burma, obtained by one of the Muséum 
collectors. 
MACROPISTHODON HIMALAYANUS. 
Tropidonotus himalayanus, Boulenger, Faun, Ind., Rept., p. 347. 
Dissection of the jaws of a specimen lately received from Sureil, 
Darjeeling, (Major A. Alcock) shows that this species belongs to the 
genus Macropisthodon. Fourteen small teeth are followed in the 
maxillary, after an interspace, by two large, backward-directed 
fangs. In T. subminiatus, the condition is somewhat similar, but 
the interspace is not so clearly marked. Evidently the separation 
between the two genera is not a natural one, but the great number of 
forms included in Tropidonotus, in which I would propose to leave 
submintatus, makes it convenient. 
COLUBER RADIATUS. 
A specimen from Cuttack, Orissa, (R. T. Crighton). I am 
not aware that the species has hitherto been recorded from this 
part of India. The late Prof. J. Wood-Mason corresponded with 
the donor about the specimen, which has been in the Museum for 
many years; but it appears to have been mislaid at the time when 
Mr. W. L. Sclater was compiling his List of Snakes.

ABLABES BALIODIRUS.* 2, 
Specimens from Java and the Malay Archipelago. 
ABLABES GILGITICUS,* sp. NOV. 
Diagnosis.—Habit slender; head small; tail short, ending in a 
well developed spine.! Rostral deeper than broad, visible from 
above; nasal divided ; eye half as long as snout; prefrontal un- 
divided, its length much greater than that of the sutures between 
the internasals; frontal as long as its distance from the snout, 
much shorter than the parietals; one pre-and one postocular ; 
loreal large, much longer than deep; temporals 1+2; 7 upper 
labials, third and fourth entering eye; 4 lower labials in contact 
with the anterior chin shield, which is larger than the posterior. 
Scales smooth, in 15 rows; ventrals 158; anal entire; caudals 34, 
Coloratvon—Back and sides dark brown, each scale edged, spotted 
L A similar spine occurs in other members of the genus, notably A. rappit 
but is not so large in any Indian form as in the new species.
