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 ; siibarticiilar tubercles moderate ; a distinct

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

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

2. Nototrema plumb eum. (Plate XXYIII. fig. 1.) 



Very closely allied to A\ 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 6U millim.

Yomerine teeth in two slightly oblique series between the choanas. 

 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

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

 plete metamorphosis in the maternal pouch : whilst in N. marsii- 

 piaium they leave the pouch in the tadpole state.
