Skogsberg (1920) has pointed out the close resemblance between this species and C. haddoni Brady & Norman. The two species are distinguishable by the short spines on the posterior dorsal angle of the shell of C. bispinosa and the number of spines on the principal setae of the first antennae of the males. Skogsberg states (1920, p. 675) that the areas of distribution of the two species do not coincide. Muller (1906, 1908), however, recorded the two species from the same plankton samples, and in the samples at present under consideration they also occur together. There must then be at least an overlap in their distribution. Conchoecia chuni Muller. For synonymy and description see Skogsberg, 1920, p. 636, fig. CXix. A single adult female occurred in the 250-100 m. sample from Station WS 996. Conchoecia curta Lubbock. The synonymy of this species is extremely complex and uncertain. Skogsberg (1920) discussed the position and re-described the species. The material from the Benguela current first survey clearly falls within the scope of the species as described by him. It was present in large numbers, of both adults
