SCANDINAVIAN CETACEA. 267 



1843. As far as I know, it has only once been obtained on the coasts of Europe, viz., the 14th 

 November, 1827, near Ostend; also a female. These are the only times that it has with certainty 

 been observed. It seems, therefore, to be quite rare. The shoulder-blade found by Professor 

 C. J. Sundevall, on the coast of Norwegian Einmark, may possibly belong to this species. 



3. B. lATiCEPS, Grmj. Herring whale. Swedish " Sillhval." 



Dorsal fin of usual size. Processus coronoideus of the lower jaw high and conspicuous. 

 Vertehræ 55. Axis alone of the cervical vertebree with ring-like transverse processes. Bibs 13 

 pairs, the \sf of which has the upper end forked or biceps. Lower arm-bones very narrow, their 

 length being 9 — 11 times their ividth at the middle. Baleen black.

I have previously stated my reasons for giving this species the name " Sild-Qval," adopted in 

 Norway, or in Swedish Sill-Hval (Herring whale). Notwithstanding Strom's statement, that this name 

 is only used for smaller whales, I have myself observed that it is used for large Fin-whales, and in 

 the vicinity of Bergen for all Fin-whales that are not Bay whales. Rudolphi considered it the same 

 species as the succeeding, or Fabricius' B. rostrata, from which, however, it differs so much, according 

 to the above-given characters, that recently they have been considered as of different genera. He even 

 supposed that Linne's B. boops was of the same species. As it would be difficult to decide what 

 species it was that Linné described under this name, I have been unwilling to give it this name, but 

 considered that I ought to retain the one given by J. E. Gray. Brandt and Ratzeburg have included 

 several species in their Balæna rostrata, at least even the Balænoptera musculus described above, as may 

 be seen from their extensive synonymy for this species, which at that time probably had no synonymy 

 at all. They have, however, increased the knowledge of it by giving a figure of the animal, viz., of the 

 same specimen of which the skeleton is described by Rudophi, and have informed us that the specimen 

 was a female. S. Nilsson has, at the place referred to, under the name of " Sillvhal" [B. physalus, 

 Fabr.), confounded with this species at least one other, viz., the B. musculus, as will be seen both 

 from the description (54 — 61 vertebrae, ribs 13 — 15, and length 65' — 70'), and by the synonymy 

 mentioned by him. Fabricius' name, B. physalus, cannot be given to it, as it probably is not this 

 species that he refers to, and it is impossible to say what species it really is that he describes under 

 this name. J. Reinhardt', however, has considered Fabricius' B. physalus to be the same species as
