yellow; a straight, blackish longitudinal streak runs through 

 the eye. Lower parts yellow ; each ventral with a black spot 

 on each side. 



East-Indian archipelago. 30 inches long ; tail 7 inches. 



Zamenis brachyurus. PI. 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 praeocular, large, extending to the 

 vertical ; two postoculars. Upper labials eight, the fourth and 

 fifth entering the orbit; temporals 2 + 2 + 3. Scales elongate, 

 narrow, in twenty-three series. Ventrals 225; anal entire; sub- 

 caudals46; ventrals rounded, not keeled. Eye 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. 



HERPETiETHiops (gcu. 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. 



Herpetcethiops Bellii. PI. 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];
