Type material The unique type, an ovigerous female measuring 84 mm, could not be found in the BMNH and is presumed lost. Fortunately the description and figures given by Willemöes­ Suhm (1874 b) are clearly of C. pellucida as understood by modern taxonomists. As the characteristic features of this species are very distinctive its status is not in doubt, despite the loss of the type. The type locality is off Cape St. Vincent, 35 º 47 ’N, 8 º 23 ’W, in a trawl from 1090 fathoms. Material examined (54 specimens) North Atlantic: 3 lots (BMNH), 5 lots (ZMUC), 9 specimens. North Indian: 1 lot (ZMUC), 1 specimen. South Indian: 10 lots (ZMUC), 11 specimens. Central Indo­ Pacific: 2 lots (USNM), 13 lots (ZMUC), 21 specimens. South Pacific: 6 lots (ZMUC), 6 specimens. Tasman Sea: l lot (AM), 3 lots (ZMUC), 4 specimens. Great Australian Bight: 1 lot (SAMA), 1 lot (ZMUC), 2 specimens. Diagnosis (female only) Body length up to 85 mm. Head about as long as deep; almost as long as first six pereonites combined; oval when viewed laterally, with slightly ...
