Pelolates , in having a large, sharp-edged tubercle on the 
inner edge of the ankle, but it differs from them at first 
sight, by the head and body being compressed and high, 
the mouth very large, and the eyes convex on the side of the 
forehead. 
Perialia Eyrei , t. 2. f. 3. — Olive, sides of the face, and 
body blackish brown ; face varies with white streak ; the sides 
of body marbled with unequal white spots; limbs brown

Inhab. Australia, on the banks of the river Murray. 
Perialia? ornata , t. 2. f. 2. — Pale grey, back and sides, 
marbled with symmetrical dark-edged spots, those of the 
middle of the back being generally confluent, of the face 
elongate, band-like; the legs dark-banded, beneath white. 
Inhab. Port Essington. 
Somewhat like Discoglosus pictus in appearance. The 
internal nostrils are far apart, with an elongate group of 
palatine teeth level with their hinder edges. 
Taking advantage of the space of the plate, figures of 
the following species from the same country, which have 
not hitherto been illustrated have been added. They were 
described or noticed in the list before referred to. 
1. Cystignathus dorsalis, t. 1. f. 2. Gray , Ann. Nat. 
Hist. 1841. 
2. Phryniscus Australis, t. 2. f. 1. Hum. and Bib. E.

Soc. 1838. 57. 
III. Mr. Eyre having brought home with him the draw- 
ing of a species of cray-fish found near the river Murray, 
which is called by the natives Ukodko , I have been in- 
duced to examine the different species of Astaci in the 
British Museum collection, which have been received at 
various times from Australia, for the purpose of attempting 
to identify it.
