the penultimate joint rather slender and attenuated, natatory setae densely 

 plumose and extending to the tips of the apical claws. Mandibles normally 

 developed. Maxillae with the masticatory lobes attenuated, the outermost one 

 armed with 2 strong denticulated spines in addition to the usual curved 

 bristles; palp narrow, with the distal joint cylindrical in shape. Maxillipeds 

 with the vibratory plate well developed, palp (in female) comparatively small, 

 not subdivided. Anterior legs remarkably short and stout, with the penulti- 

 mate and antepenultimate joints wholly coalesced. Posterior legs much more 

 slender, with only a single seta inside the penultimate joint, which terminates 

 in several irregular lobules partly embrasing the minute terminal joint; the 

 latter provided outside with a slender seta and at the tip with a much smaller 

 hamiform bristle accompanied inside by a knob-like projection of the joint. 

 Caudal rami very narrow, linear in shape, with the apical claws slender and 

 almost straight, dorsal seta small and not far remote from the tip. Propagation 

 chiefly parthenogenetical. 



Remarks. In the restriction here adopted this genus only comprises a 

 limited number of species chiefly distinguished by the coarse, ventrally flattened 

 shell and by the structure of the anterior legs. The type of the genus is the 

 well-known C. pnbera O. Fr. Miilier, and in Europe only one additional species, 

 the magnificent C. bispinosa Luccas, has as yet been found, the other species 

 being from more southern latitudes. Only the type species is represented in 

 the Fauna of Norway.

Specific Characters. Female. Shell very tumid, seen laterally, oval 

 triangular in shape, greatest height somewhat in front of the middle and con- 

 siderably exceeding half the length, dorsal margin gibbously arched in its 

 anterior part and sloping rather steeply both in front and behind, ventral 

 margin almost straight, though slightly bowed in the oral region, anterior 

 extremity obliquely rounded, posterior gradually narrowed, with the lower 

 corner rounded off; seen dorsally, broadly ovate, with the greatest width in
