HISTORY OF BRITISH CRUSTACEA. 
Coni lera cylindracea, Montagu, sp. (Plate XIY. fig. 
6.) — Body smooth, not punctured; last joint of abdomen 
longer than wide, rounded at the end and the sides, arched 
about the middle. 
Coast of Devonshire (Montagu) . 
Dr. Lukis of Guernsey has kindly informed me of the 
habit of this species. He took upwards of a dozen feeding 
together within the orbit of the whiting. The globe of the 
eye was nearly detached from the surrounding parts. The 
fish was large and did not seem out of condition. The 
Cornier must have been there some time, as they were re- 
markably blanched (Letter, July 18, 1856). 
Gen. 132. ROOINELA, Leach . 
Two first joints of upper antennae nearly cylindrical. Eyes 
very large, somewhat convex, converging in front and nearly 
approaching. 
Rocinela Danmoniensis, Leach. — Of a horn-colour, with 
dark-coloured eyes. 
Plymouth Sound (Dr. Leach). 
Rocinela mqnophthalma. (Plate XIV. fig. 7.) — Eyes 
nearly occupying the whole surface of the head.
