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.
