So8 LILLJEBORG ON THE 



rows, excluding the. shortest, were counted on each side on the specimen preserved in Bergen.' Their 

 colour, when fresh, is, according to Eschricht, light blue with white streaks. Those in Christiania 

 and Bergen are of a similar colour, but, in consequence of their dry state, somewhat darker than 

 the colour stated by Eschricht — dark grey, with more or less conspicuous longitudinal greyish- 

 white dashes, somewhat lighter inwards, and with grey bristles. The anterior blades were slate 

 coloured. This colour agrees very nearly with that given by Schlegel, and seems to be quite 

 constant.^ 



The colour of the specimen obtained near Bergen was, according to Dr. Koren, dark grey 

 on the upper side of the body, the pectoral and the upper side of the caudal fin ; belly and 

 lower part of caudal fin, white. It is, according to Eschricht, hght grey on both the upper and 

 lower sides of the body, and on both sides of the pectoral fins. This colour may have been 

 caused by the advanced state of decomposition. The colour, according to Van Beneden, is, above, 

 greyish-blue ; beneath, white. The colour, according to Companyo, is, above, dark slate colour ; 

 beneath and on the lateral parts of the pectoral fins, white ; the furrows on the lower side of the 

 body bluish. The colour of the one figured by Schlegel was, above, black; beneath, white ; the 

 upper side of the pectoral fins and the outer side of the upper lip are on the figure also 

 black ; this description seems to be the most reliable, as the specimen was fresher than the 

 others. 



The Skeleton. — Its general form corresponds with the elongated body. The ribs are, in com- 

 parison with the length of the skeleton, small and short, and the bones of the anterior extremities 

 small; the skull, the length of which is about \ of the length of the entire skeleton, resembles the 

 skull of the Bay whale very much, but has the facial part, in front of the lateral notches of the superior 

 maxillaries, somewhat narrower. The width of this is less than half the width of the skull -^ the 

 posterior part of the skull is also narrow, so that its width is less than half the length of the 

 skull, whereby the whole skull is of a more slender form than in the above-mentioned whale, with 

 the exception that the lower jaw-bones are more strongly curved ;* the beak is almost twice as long 

 as the hinder, wider part of the skull, from the notch of the superior maxillaries. The distance 

 from the middle of the lateral borders of the beak to the lower jaw-bone is considerable, although 

 less than in Balæna. The lower jaAv-bones extend beyond the point of the upper jaw. I have made 

 the following notes from the skeleton in Bergen:^ — Number of vertebrae 62, viz., dorsal 15, 

 lumbosacral 15, caudal 25; cervical vertebrae 7, as usual, and all free. Atlas and axis most 

 strongly developed ; the former has a wide and rounded corpus ; the posterior articulating sur- 

 faces, united below without any sign of distinction, do not extend to the upper borders of the 

 arcus, but reach the lateral edges of the corpus, so that its outer gradually curved edges 

 coalesce with those of the latter; they form, on the middle of the lower edge at their junction, 



^ Eschricht states nearly 400. 



^ Van Beneden states that the colour of those observed by him was black on the outer side and 

 white on the inner side. 



^ According to the skull in Christiania. 

 The length given was taken by me along the curve of these bones on the outer side. 



5 I will here acknowledge my thanks to Dr. Koren for having afforded me the opportunity of 

 examining this skeleton, and giving me much necessary information. The skeleton was cleaned, but not 

 put together.
