BET. A. M. NOMTAN' OX THE CRUSTACEA. 23 



excavated with very large cellular areolae. Length about one 

 sixth of a line. 



Cythere cellulosa is the smallest species of this genus with 

 which I am. acquainted, and is a very remarkable and interesting 

 form, the chief peculiarity of which consists in the very large 

 cells which are excavated in the valves. I have procured it in 

 sand from Berwick-on-Tweed, Lamlash Bay, and Guernsey ; and 

 Mr. Gf. S. Brady has specimens from Donegal Bay.] 



In concluding the descriptions of the preceding new Crustacea, 

 I must express my sincere thanks to Mr. Gf. S. Brady for the 

 time and care which, amidst many pressing engagements, he has 

 so kindly bestowed in drawing for me the admirable figures 

 which illustrate the species. 



The following table is intended to show the total number of 

 Crustacea taken during the course of the three seasons' dredging 

 on the Durham and Northumberland coasts.
