point. Upper parts brownish, marbled with olive, some of 

 the large tubercles surrounded by a black ring ; parotoids and 

 the tubercles of the series behind it whitish, more or less 

 distinctly edged with black ; limbs irregularly barred, lower 

 parts white, marbled with brown, especially across the 

 stomach. 



Mr. Wray says that this species is rare, he having obtained 

 two specimens only, and that it inhabits the hills of Perak 

 from 800 feet downwards. 



Polypedates Jeprosus^ sp. n. (?). 

 (PI. XVI. figs. A, a, a!.) 



Habit hyliform, with very large and broad head. Vome- 

 rine teeth rudimentary, on a short linear ridge, the ridge on 

 each side being close to the choana. No conical papilla on 

 the middle of the tongue. Snout very broad, with the can- 

 thus rostralis angular, and the loreal region sloping ; nostril 

 lateral, but close to the tip of the snout. Interorbital space 

 wider than the upper eyelid. Tympanum distinct, not quite 

 as wide as the eye. Fingers quite free ; toes broadly webbed ; 

 disks of fingers and toes large, the largest being at least half 

 the size of the tympanum ; subarticular tubercles well deve- 

 loped, inner metatarsal tubercle ovoid. The tibio- tarsal 

 articulation reaches the extremity of the snout, when the hind 

 limb is drawn forward along the side of the body. All the 

 upper and lateral parts are covered with rough tubercles, 

 between which numerous very large ones like glands are scat- 

 tered over the back, the upperside of the head, and the upper 

 parts of the limbs ; also a part of the tympanum shows some 

 minute granules. The whole frog is bluish black in spirit ; 

 but some of the large tubercles are of a lighter colour^ either 

 entirely, or only the roughnesses with which they are covered 

 are whitish j lower parts coarsely granular, with vermiculated 

 whitish lines. 



Distance between snout and vent 30 lines ; distance between 

 the angles of the mouth 1 1 lines ; distance between the vent 

 and extremity of fourth toe 49 lines. 



Mr. Wray gives the following notes : — " Above rich warm 

 chocolate-brown. The tops of the warts paler, some of those 

 on the back yellow. Beneath — body, legs, and arms jet- 

 black, irregularly marked with pale bluish grey. Under sur- 

 face of fingers and toes bright rose-red. Web to feet and 

 top surface of all the disks same colour. Irides pale warm 

 brown, pencilled radially with black, a fine yellowish-orange 

 line forming inner edge to irides.
