Nototremn peruanum. 



Tongue subcircular, slightly nicked arid free behind. Vo- 

 merine teeth in two short, straight, transverse series between 

 the choanae. Head moderate, broader than long ; snout 

 rounded, as long as the diameter of the orbit; loreal region 

 slightly concave ; canthus rostralis distinct ; interorbital space 

 narrower, or at most not broader, than the upper eyelid ; 

 tympanum distinct, two thirds the diameter of the eye. 

 Fingers with a very slight rudiment of web; toes one-third 

 webbed ; disks of fingers and toes smaller than the tym- 

 panum ; subarticular tubercles moderate ; a fold along the 

 inner edge of the tarsus. The tibio-tarsal articulation reaches 

 the tympanum or the eye. Upper parts covered with smooth 

 warts of unequal size, the largest of which are parotoid-like 

 or may be confluent into longitudinal folds ; lower parts 

 granulate. Greenish above, with insuliform black-edged 

 dark spots, most of which correspond to the larger glandular 

 tubercles; limbs with dark transverse bars ; whitish beneath. 

 Male with a subgular vocal sac. 



From snout to vent 43 millim. 



Several specimens from Carao, 7000 feet altitude. 



Very closely allied to iV. marsupiatum, D. & B. Distin- 

 guished by the narrower interorbital region and the extra- 

 ordinary development of the dorsal glands. 



Bufo cophotis. 



Crown without bony ridges; snout short, blunt; inter- 

 orbital space as broad as the upper eyelid; tympanum quite 

 hidden, but eustachian tubes perfectly developed. Fingers 

 and toes short, flattened, blunt, with double subarticular 

 tubercles ; first finger extending a little beyond second ; toes 

 one-third webbed ; two moderate, feebly prominent meta- 

 tarsal tubercles ; no tarsal fold. The tarso-metatarsal articu- 

 lation reaches the eye. Upper parts covered with smooth 

 tubercles of different sizes, pierced with large pores, many of 

 which are comparable to so-called parotoid glands ; such a 

 large gland on the middle of the upper surface of the leo- or 

 cms. Dark olive ; upper parts speckled with black, lower 

 parts marbled with greyish white. Male without vocal sacs,
