As upon the whole the \-entrals of the male as to contour and shape are different from those iu the preceding species, so it is also the case with the appendices. Tlie ventrals are also here coa- lesced'), but only for a short way (in one specimen of the total length of go'^'" the coalesced part has a length of 16™'"); the small cut in the posterior edge iu Sc. caiiicula has here become a large slit (in the specimen mentioned above about 26"""); the dermal teeth also spread to a greater extent on the ventral side of this part of the fin. As furthermore no lateral fold of the skin is found on the ventral side covering the base of the appendices, and corresponding to the one mentioned in Sc. canicIlia^ no <bell» is formed here. The appendix reaches just outside the posterior fin edge; it is far more big and clumsy than in .SV. canicula^ but still the details remind of the latter, the}' are only coarser and more conspicuous. In a specimen of a total length of 90'-'" the following measures were foxuid:. f-.
