yellow; a straight, blackish longitudinal streak runs through 
the eye. Lower parts yellow; each ventral with a black spot

East-Indian archipelago. 20 inches long ; tail 7 inches. 
Zamenis brachyurus. Pl. VI. figs. A, A’. 
This species resembles in general habit a small Dromicus. 
Rostral shield scarcely broader than high, extending to the 
upper surface of the snout; anterior frontals half as large 
as the posterior. Vertical of moderate size, five-sided, rather 
shorter than the occipitals, which are rounded behind.  Lo- 
real as high as long; one preocular, large, extending to the 
vertical ; two postoculars. Upper labials eight, the fourth and 
fifth entering the orbit; temporals 24-2+3. Scales elongate, 
narrow, in twenty-three series. Ventrals 225; anal entire; sub- 
caudals 46; ventrals rounded, not keeled. Hye rather small, 
with round pupil. The last maxillary tooth is the largest, and 
separated from the others by an interspace. Upper parts 
brownish olive; the upper side of the head and the anterior 
part of the trunk are irregularly spotted with brown, the brown 
spots being arranged in longitudinal series, and narrowly edged 
with yellow. The posterior part of the trunk is immaculate. 
Anterior ventral shields brownish, each with a yellowish poste- 
rior edge ; posterior ventral shields uniform whitish. 
We have obtained a single example from Poonah (Dekkan) ; 
it is 17 inches long, the head measuring 7 lines, and the tail 
2 inches. 
Hrrrera£trutrors (gen. nov. Dryadid.). 
Body and tail slender, scarcely compressed ; trunk with about 
150 ventral shields, which are keeled; head somewhat elongate, 
rounded in front, flat above; eye of moderate size, with round 
pupil; nostril lateral, between shields. Plates of the head re- 
gular; loreal present; one anterior and two posterior oculars. 
Scales rather elongate, smooth, without apical groove, in fifteen 
rows; ventrals strongly bent up the sides; anal entire. The 
two posterior maxillary teeth are the longest, not grooved, sepa- 
rated from each other and from the preceding ones by a short 
interspace. 
Herpetethiops Bellu. Pl. VII. fig. B. 
Head rather narrow, distinct from neck. Rostral shield 
scarcely broader than high, reaching the upper surface of the 
snout; anterior frontals half as large as the posterior, about as 
long as broad, Vertical bell-shaped, as large as a superciliary, 
and not much shorter than the occipitals, which are short and 
rounded behind. Loreal quadrangular, much longer than deep;
