5. NOTOTREMA. 417 
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 
earried 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. From snout 
to vent 72 millim.

2. Nototrema plumbeum. (Prater XXVIII. fig. 1.) 
Very closely allied to NV. 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 lghter; beneath uniform 
lead-colour. From snout to vent 66 millim.

Nototrema testudineum, Espada, Jorn. Sc. Lisb. ix. 1870, p. 62, and 
Viaj. Pacif., Vertebr. pl. 4. f. 2. 
Vomerine teeth in two slightly oblique series between the choane. 
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 
back studded with stellate bony deposits. Uniform lead-colour 
above, lighter beneath. Otherwise as in NV. marsupiatum. From 
snout to vent 82 millim. 
Ecuador; Peru.

In this species, as in V. oviferum, the young undergo their com- 
plete metamorphosis in the maternal pouch; whilst in 1. marsu- 
piatum they leave the pouch in the tadpole state.
