342 BRITISH ENTOMOSTRACA. 



The abdomen is like that of the preceding, and the 

 ovarian tubes are long and slender, at least twice the length 

 of the body. Turton describes the ovaries as " clear white." 

 Perhaps they may be so in the living animal, but in the 

 specimens preserved in spirits, they are of exactly the 

 same colour as the body. In one specimen^ however, one 

 of the tubes is broken, and the ova have escaped, and in 

 this the tube is white. 



Length of the body about half an inch ; ovaries, fully 

 one inch.
