In a systematic work, this genus would hold a very con- 
spicuous and important place, as it is not referable to any 
family hitherto established. Its breathing organs are the 
same as in the other Crustacea Malacostraca, to which 
subclass it belongs.

HERBSTIAN NEBALIA. 
Grey or cinereous-yellow, with black eyes. 
Inhabits the European ocean. 
This curious animal was first described by Herbst, in his 
elaborate work on the Linnean genus Cancer, and after- 
wards by Montagu in the eleventh volume of the Trans- 
actions of the Linnean Society ; but as neither of these au- 
thors were acquainted with the exact number of legs, and 
as it constitutes a very distinct genus from any given by 
modern writers, I haye introduced it into this Miscellany, 
for the purpose of pointing out its characters. 
It is not uncommon in the south-west and western 
coasts of England, occurring under stones that lay on mud 
amongst the hollows of the rocks. The under figure re- 
presents the animal of the natural size, the other magni- 
fied. To avoid confusion, the members of one side only 
are exhibited.
