PRIDEAUX'S HIPPOLYTE. 293 



Moorii merely as a variety a view which Dr. Edwards 

 had already taken in his " History of Crustacea," although 

 it still remains to be proved which of the two forms of 

 rostrum is, on account of the comparative frequency of 

 occurrence, to he considered as normal. 



The wrist of the second pair of legs has only two short 

 and one long articulation ; the abdomen is remarkably bent 

 at the third segment. The whole animal is smaller than 

 H. varians, and of a reddish brown colour. 



This is certainly a very rare species, and is not mentioned 

 in Mr. Thompson's Irish Fauna, nor in that of Cornwall 

 by Mr. Couch. I have received it, however, from the 

 neighbouring coast of Devonshire. 



The vignette below appears to be a representation of the 

 Common Shrimp (Grant/on vulgaris), and was taken from 

 a tesselated pavement discovered at Cirencester in 1783.
