the distal one single. All the toes clawed. The scale-like granules 

 on the upper surface arranged as on the fingers. 



Brownish grey olive, with 5 to 6 transverse, broad, wavy, 

 brownish bands, with pale posterior margins on the back, and 12 to 

 13 more indistinct bands on the tail with the angle directed 

 backwards. Sides faintly reticulated with brown. Under surface 

 pale yellowish, brightest on the middle of the abdomen. Disks 

 bright silvery white in life. Length 2," ll'", tail 3", 2"' = 6", 1'". 



This species is common in Bengal, and is closely allied to H. 

 Coctcei, from which it is distinguished by the tubercle on the side of 

 its neck, by the absence of the tubercles on the sacral region, the 

 spiny character of the lateral caudal tubercles and the smaller 

 tubercle above it, the greater number of its upper labials and by 

 its coloration. 



Nycteridium Himalayanum, n. sp. 



Head rather flat : snout broader, natter and more rounded than 

 in N. Schieideri. Fingers and toes with a more developed mem- 

 brane. Uniformly granular above, with the exception of a line of 

 large, round, flat, scale-like granules along the sides from behind the 

 fore limb to the loin. Thirty-six longitudinal rows of scales in the 

 middle of the belly. Two pairs of mental shields, the anterior 

 nearly twice as large as the posterior. Eleven upper and eight 

 lower labials. A line of small shields above the upper labials. A 

 pair of supranasals behind the rostral, the two separated by a 

 small azygos shield. Tail broken off. 



Uniform greyish above with a shining lustre, marbled with 

 blackish in short lines. A dark line far behind the eye along the 

 side, minutely punctulated with black, a spot to each granule 

 most numerous on the limbs, the sides of the body and head ; under 

 surface yellowish. 



The rather strongly webbed feet of this species would seem to 

 connect Ptychozoon and Nycteridium. The glands behind the ear in 

 the position of the paratoids are prominent structures, filled with a 

 white cheesy substance. Darjeeling ; 3,000 feet.
