each side of the belly, which is uniform yellow. Scales smooth, 
in 21 series. Upper labials 9, the fifth and sixth coming into 
the orbit; two anteridr and two posterior oculars; occipitals 
rounded posteriorly, without larger scale behind, 
Head rather narrow; body and tail elongate. Rostrai shield 
moderate; the upper anterior ocular is in contact with the 
vertical ; the lower is small, apparently a separate portion of the 
fourth upper labial; the sixth labial forms the lower third of the 
posterior margin of the orbit. Temporal shields small, scale-like, 
in four transverse series; the front series is composed of two 
shields which are in contact with the oculars. The posterior 
pair of chin-shields are separated from each other by inter- 
mediate scales. ‘Two very indistinct grooves at the apex of the 
scales (invisible in numerous scales). Ventral shields 219; anal 
bifid ; subcaudals 120, Length of head 7 lines, of trunk 17 
inches, of tail 8 inches. 
I have mentioned this species as var. B. of Zamenis ventri- 
maculatus (Colubr. Sn. p. 106), expressing my doubts as to its 
being distinct from it, Having found other specimens in the 
museum at Fort Pitt, said to have come from Western India 
(Kurrachee), I can no longer hesitate in considering them as 
a separate species. There are five specimens in the British 
Museum. 
Psammophis teniata. . 
Allied to Ps. sibilans, but having only one anterior temporal 
in contact with the oculars. Anterior ocular not reaching to 
the vertical. Yellowish olive, with four green longitudinal 
bands edged with black ; labial shields without any markings. — 
- Specimens of this snake have been known to me for several 
years; but I hesitated to consider it as a distinct species until 
lately, when I had an opportunity of examining several others 
- in the Fort Pitt Museum: they quite agree with those in the 
British Museum, and also come from India, very probably from 
the western parts. 
Phragmitophis tricolor. 
Herpetodryas tricolor, Schleg. = Cyclophis tricolor, Gthr., 
differs so much in its, physiognomy from the other species of 
either of the genera to which it has been referred, that it will 
be better to establish for it a separate genus, for which I pro- 
pose the name of Phragmitophis. The technical character by 
which it may be distinguished from Cyclophis is—loreal none, 
united with the posterior frontal. 
Cyclophis, Phragmitophis, Dryocalamus, and Hydrophobus form 
a separate group in the family of Dryadidz, which approaches 
the Calamaride and Coronellide, either by having some shields
