SCANDINAVIAN CETACEA. 257 



by gas, and the circumference is, therefore, probably too large. The head, seen from the side or 

 from above, tapers considerably anteriorly, although the point is obtuse. The lower jaw is longer 

 as well as broader than the upper jaw, with a rather high imder lip on both sides, which surrounds 

 the borders of the upper jaw or upper lip when the mouth is closed. There is, on the upper side 

 of the head, somewhat in front of the angle of the mouth, a shallow concavity, in which the nasal 

 openings are placed. The navel is somewhat before the middle of the body, and behind this the 

 body tapers considerably backwards, particularly if seen from the upper side. The hinder part of 

 the body, or the tail, behind the anal opening, which is placed somewhat behind the beginning of 

 the hinder third of the body,^ is, when seen from the side, almost straight to near the base of the 

 caudal fin ; the height is even somewhat greater nearer the caudal fin, being rather less than about 

 half the greatest height of the body. It is, if seen from above, much compressed behind the 

 anus, so that its width is not more than half its height, and nearer the caudal fin even less, and 

 its upper and lower thin edges extend on the caudal fin between its lobes to near the fork in the 

 middle of its hinder edge. The hinder part of the body or tail is thus of the same form as that of the 

 dolphins. Head somewhat shorter than I the length of the body. The pectoral fins, placed somewhat 

 before the end of the anterior third of body, are small, narrow, and short ; their length about I or 

 i length of body ; they are lancet shaped and pointed, with the fore and hind edges smooth.^ 

 The dorsal fin, with the beginning of its base almost directly above the anus, is small and directed 

 backwards,'and was, on Schlegel's specimen, 1' high Qj length of body), and it had about the same 

 proportion to the length of the body on the specimen described by Van Beneden. Caudal fin of 

 moderate size, its width, "according to Van Beneden, about ~ length of body (its width being 10' 1" 

 on the specimen described by him), and deeply forked in its hinder edge. Eyes small, and imme- 

 diately above the angles of the mouth. Blowers with two longitudinal, forward converging, 

 approximate openings on the upper side of the head, somewhat before the eyes, in a small 

 concavity, surrounded by a circular dermal elevation.^ The orifices of the ears, between 

 the eyes and the pectoral fins, but nearer the former, are so small that a goose-quill can 

 hardly be introduced into them. The external genital organs in the male are half way 

 between the navel and the vent, and in the female close before the latter. The furrows, 

 which in larger specimens are 11", or more, deep, occupy the entire lower side of the body 

 from the borders of the under lip, and the middle ones, which are the longest, extend all 

 the way to the navel; they are very numerous, and extend upon the sides behind the 

 angles of the mouth and to the base of the pectoral fins. There are some short bristles 

 on the upper side of the point of the upper jaw, and on a wide dermal band on the 

 middle of the chin ; but these are sometimes absent. Baleen short ; the longest blades of 

 the specimen caught at Oster-Risor were 3' long in a straight line. About 360 transverse 



^ It was 12' 3" before the hinder edge of the caudal fiu in the specimen described by Schlegel, on 

 ■which the above description of the external form of body is based. 



2 They appear, according to both Companyo and Eschricht, to be often injured on stranded 

 specimens. The terminal phalanges were missing on the skeleton in Bergen, and those next to them 

 were injured by caries. 



^ According to Companyo, they are situated on a pyramidical fleshy convexity. Martens has 

 also drawn such a convexity in the figure of his Winnefish. In this there seems to be some deviation 

 from Schlegel's rorqual.
