Plates XXXII. to XXXVI. 
The following notes deal with some species of Anomurai 
The first three are true hermit crabs of the family Paguridcey 
which are closely allied to each other, belonging to that divi- 
sion of the family whose chief characteristics are the posses- 
sion of a pair of modified appendages on the first, and ano- 
ther on the second, abdominal somite in the male, and a pair 
on the first in the female. The female also is provided with 
a brood pouch, which arises from the fourth somite on the 
left side, and covers the unpaired biramous appendages which 
serve for the attachment of the eggs. These three species are 
referred to the genus Faguristes. Of the four remaining 
species, three belong- to the Forcellanidce. Petrocheles aus- 
traliensis, Miers, is a fine species, showing well the transition 
to the Galatheidce, and as far as I know has never been figured. 
Of Polyonyx traiuvei^sus, Haswell, the same may be said ; so 
it is here figured, and the description extended. Lastly, a 
Galathea, belonging to the group which contains G. austra- 
liensis, Stimpson ; G. aculeata, Haswell ; and G. magni-fica, 
Haswell, 'S described — though provisionally — as G. setosa, for 
the first time.

The carapace anterior to the cervical groove is only 
slightly convex from side to side, anteriorly depressed, rather 
oblong viewed from above, the sides behind the curve of an- 
terior angles being nearly straight ; its surface is smooth and 
polished except for some small scattered punctations, but to- 
wards the sides it becomes somewhat rough or rugose. The
