GENUS MUNIDA. 



207 



in favour of the generic separation of this form, have re- 

 ceived an interesting confirmation, in the existence of a 

 new and elegant species which I find among the fine col- 

 lection of Crustacea procured by my friend Mr. Darwin. 

 It possesses all the characters which I have recorded above 

 as generic, and in all of which our own species agrees, 

 whilst the specific distinctions are striking and obvious. I 

 have, therefore, thought it right to restore Leach's name 

 Munida to the genus, which now consists of two very 

 distinct species. 



The vignette, by Mr. C. 0. Pyne, represents part of 

 the coast between Hastings and Winchelsea.
