distinct, half or two thirds the diameter of the eye. Fingers with 

 a very slight rudiment of web ; toes half webbed ; disks nearly as 

 large as the tympanum ; subarticular tubercles moderate ; a distinct 

 fold along the inner edge of the tarsus. The hind limb being 

 carried forwards along the body, the tibio-tarsal articulation reaches 

 the eye or not quite so far. Skin smooth or warty above, granulate 

 beneath. Above uniform bluish olive (in spirits), or greenish olive 

 with bluish or dark-green, black-edged longitudinal spots, and with 

 transverse bars on the limbs ; beneath whitish, immaculate or brown- 

 spotted. Male with an external subgular vocal sac. Prom snout 

 to vent 72 miUim. 

 Peru; Ecuador. 



2. Nototrema plumbeum. (Piatb XXVIII. fig. 1.) 



Very closely allied to N. marsupiatum, from which it differs in 

 the wider interorbital space (this being considerably wider than the 

 diameter of the orbit), the larger disks of the fingers (these being a 

 little larger than the tympanum), and coloration. Above dark lead- 

 colour, minutely speckled all over with lighter; beneath uniform 

 lead-colour. Erom snout to vent 66 millim.

 Viaj. Pacif., Vertebr. pi. 4. f. 2. 



Vomerine teeth in two slightly oblique series between the choanse. 

 Interorbital space deeply concave ; tympanum not very distinct. 

 The hind limb being carried forwards along the body, the tibio- 

 tarsal articulation reaches nearly the tip of the snout. Derm of

In this species, as in N. oviferum, the young undergo their com- 

 plete metamorphosis in the maternal pouch ; whilst in N. marsu- 

 piatum they leave the pouch in the tadpole state.
