III. Mr. Eyre having brought home with him the drawing of a species of

UKODKO, I have been induced 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.
As we have three very distinct species which have not yet been described
