ORCIIESTIA DESHAYESII.

finger : palm occupying nearly the whole of the inferior 
margin, with a large tooth at the inferior angle, against 
which the extremity of the curved finger impinges when 
closed. The coxa of the fifth pair of legs is bilobed, 
but is not quite so deep as the coxa of the preceding pair. 
Fifth pair of legs shorter than the sixth and seventh. 
This species was first taken by Savigny in Egypt, when 
he visited that country with the first Napoleon. A spe- 
cimen in the British Museum was taken on the British 
coast. One in the Museum at the Athenaeum, Plymouth, 
was taken by the late Dr. Edward Moore, under Mount 
Batten, in Plymouth Harbour. An English specimen of 
an unknown locality has been for many years in Mr. West- 
wood’s collection, and Professor Kinahan, who states that 
it is local and rare, has sent us specimens from Carrick- 
fergus. In its general form it is less compressed than 
O. littorea. The widely separated recorded habitats in- 
duces us to believe that, like O. mediterranea , it has 
hitherto been overlooked, a fact that has been too common 
in this order of Crustacea. 
The accompanying vignette of Mount Batten is from 
the pencil of our friend Mr. Philip Mitchell, of the New 
Water Colour Society.
