SCANDINAVIAN CETACEA. 245 



inferiores; with the 7 cervical vertebræ, in all 53 vertebræ.' Six out of the 13 pairs of ribs are 

 costæ veræ, and the 7tli pair are united to the cartilage as far as the end of the sternal part of 

 the 6th pair. 



The narwhal, like the beluga, does not properly belong to the Scandinavian Fauna. It 

 inhabits the most northern Polar seas, or the regions of the Polar ice, and appears only during 

 the winter on the coasts of Greenland, and even then never south of 65° north lat. (R,ink. 

 Gronl.). It is said sometimes to appear near Spitzbergen (according to Martens), but does not 

 seem to be at all common, as Martens himself never saw it during his travels there. It exists, 

 according to Pallas, at Nova Zembla, and in the seas north of Siberia. Only one specimen has, 

 according to S. Nilsson (I.e., p. 621) been caught on the north-western coast of Norway, viz., in 

 Bindals Piord, near Helgeland. It very seldom runs far south from its northern home. Two 

 specimens were caught, in 1736, on the north-western coast of Germany (J. A. Wagner), and 

 it has been observed, some three or four times, on the coasts of England.^ There is a drawing at 

 the " Landboliojskola," at Copenhagen, representing a narwhal, that was stranded, in 1803, in the 

 " Kielerbugt " (' Stud. C. R. Sundstrom,' verbally). It does not generally appear out of the Polar 

 basin, and is, consequently, never seen in the northern parts of the Pacific. It lives, according 

 to Scoresby, principally upon cephalopods, also upon fish, sometimes taking rather large thorn- 

 backs. Scoresby believes that it kills tliese with the tusk. At all events he does not know to 

 what other purpose this weapon is applied. The statements of Fabricius respecting its breathing 

 at holes in the ice, make it probable that it uses the tusk to keep these holes open. It is social 

 and lively and quick in its movements.

Distinguished as regards external form by a small, cyhndrical, somewhat pointed nose or 

 beak, which is sharply defined posteriorly, and behind which the head rises more or less vertically, 

 with a rounded forehead-like convexity. There are two longitudinal deep furrows under the chin 

 and throat, partly along both rami of the under jaw, and partly behind and inside of the same 

 (Eschr.). Form of body rather elongate, with its greatest thickness before the middle, and the 

 fore part but little tapering, and, except the beak, obtuse. The eyes are far behind the angles of 

 the mouth, and the transverse lunate opening for the blowers, which is concave before and convex 

 behind, is above the eyes. The hinder part of the body, on the contrary, tapers, as usual, very 

 much, and is compressed towards the caudal fin. The back with a tolerably small fin which is 

 directed backwards, and is behind the middle of the body. The pectoral fins are very small, and 



^ Schlegel (1. c, p. 35) enumerates 26 caudal vertebræ, and Giebel (Die Saugetliiere, p. 113) only 

 24. I counted 26 caudal vertebræ on a skeleton in the museum at Bergen.
