SCANDINAVIAN CETACEA. 261 



with loose vertebral epipliysesj and with the exterior part of the ring-like lateral processes of the 

 3 — 6th cervical vertebræ yet cartilaginous. Number of vertebrae 61, 24 of which are caudal.^ 

 The posterior dorsal, as well as all the lumbosacral vertebræ, are ridged along the lower side of 

 the corpus, although this ridge is less perceptible on the anterior ones. Even the last of the 13 

 anterior caudal vertebræ decrease very little in length backwards. The processus transversi of 

 the last dorsal vertebra are blunt at the point, differing from those of the first lumbosacral vertebra, 

 and are directed sHghtly backwards, while the latter are directed forward. The processus trans- 

 versi of the 6 anterior dorsal vertebræ are directed forward, those of the 1st most so, and those 

 of the 6th hardly perceptibly; so much, however, that if a straight line is drawn from the 

 middle of the extremity of the one to the same place on the other, it will run in front of the 

 middle of the corpus vertebræ. The processus transversi of the 7 posterior dorsal vertebræ are 

 directed backwards, but those of the 1st and the last of them less perceptibly. Processus trans- 

 versi of the 7th and 8th dorsal vertebræ are directed to the sides. The processus transversi of 

 all the lumbosacral vertebræ, except those of the last, are directed forwards.^ Processus spinosi 

 inferiores 18. The mucous membrane of the jejunum forms, according to Eschricht, 6 — 8 

 longitudinal folds. 



The Razorback inhabits the northern part of the Atlantic, the North Sea, and the Polar Sea, 

 and runs sometimes into the Mediterranean. It may even appear further south, and in the 

 northern part of the Pacific. It does not seem to be scarce on the coasts of Norway, although it is 

 seldom caught. It is known to have been stranded there at least three times ; atKrageroin 1837,^ 

 at Oster-Risor in 1 857, and at Bergen in 1858.* I do not know any positive evidence of its ever 

 appearing on the coast of Sweden. The broken parts of a skull and of an anterior extremity 

 that are preserved in the zoological museum of the University in Lund, from the same locality, 

 and from the same skeleton as the above-mentioned atlas, viz., from Heljarp, in the vicinity of 

 Landskrona, which have been represented as belonging to Balænoptera musculus, are, as before 

 stated, of a Megaptera. I mentioned, at the meeting of naturalists in Copenhagen in 1860,^ in 

 my discourse upon the sub-fossil whale skeleton found on Griiso, that there is preserved, in 

 the cathedral in Wisby, a large vertebra that is probably one of the anterior caudal vertebræ of a 

 large Balænoptera. It seems, in form, completely to resemble the corresponding vertebra of Bal.- 

 musculus ; it is, however, not a caudal, but a lumbosacral vertebra, probably one of the posterior, 

 because the caudal vertebræ are not ridged on the lower side of their corpus, and this one 

 has a conspicuous ridge. It is, however, not known where it is from, but it may 

 possibly have been found near the Baltic." This whale has seldom, if ever, appeared on any 



^ [The number of vertebræ of the skeleton described by Van Beneden is 61 or 63. Their 

 number, according to Eschricht, is 63. Add. 1865.] 



^ The posterior dorsal vertebræ are by this easily distinguished fromthe anterior lumbosacral vertebræ. 



^ The skeleton of this whale was, according to Eschricht, preserved in Christiania, and was there 

 seen by him ; it has since been destroyed during a fire. It had been preserved by Professor Esmark, 

 according to his own statement. 



* [There is a skeleton of this species in the Royal Zool. Museum in Stockholm, obtained from 

 Hammerfest, in Norwegian Finmark, through Mr. Nordvi, which corresponds in every respect with that 

 in the museum in Bergen. Add. 1865.]
