I have not had an opportunity of examining any skeleton. It has, according to G. Cuvier, 

 67 vertebræ, viz,, cervical 7, dorsal 13,' and lumbar and caudal 47. The sternum consists of 3 

 bones, and there are 6 pairs of costæ veræ. 



It is but seldom obtained on the coasts of Scandinavia. A stuffed specimen is presei-ved, as 

 previously stated, in the Zoological Museum of the University of Christiania ; also a skull of 

 another specimen, from the south sea of Norway." It is very common in the seas of England 

 and France,

Of a somewhat more elongated form than the preceding, with a tolerably long and pointed 

 nose, limited behind by a conspicuous notch. The dorsal fin rather high, and directed strongly 

 backwards, placed a little behind the middle of the body. The circumference of the body of a 

 female, somewhat over 8' (English) long, was at the thickest place 4' 10" (Swedish), according to 

 Brightwell. Its dorsal fin was 10" high and 11^" long at the base. The pectoral fins were 15" 

 long, and the width of the caudal fin 22". Colour: — The nose, the upper lip above the angle of 

 the mouth, the lower jaw, and the lower side of the body as far as a little beyond the dorsal fin, 

 of a yellowish-white colour ; the rest of the body, as well as the fins, black, with a tinge of 

 pm'ple. It reaches a length of over 9'. 



I have had the opportunity of examining skeletons of this species at the Physiological 

 Museum of the University of Copenhagen. One of the skeletons was 9' long ; its skull was 

 1' 7j" long and 10^" wide across the temporal bones. Length of the nose about Ijrds its width at the 

 base. The skull was particularly distinguished by the projecting area before the blowers being 

 somewhat convex behind, and level and pointed in front. The intermaxillary bones on the upper 

 side of the nose (the rostral ridge) very little elevated, and towards the sides gradually running 

 into the superior maxillary bones. The upper jaw without longitudinal fossæ on the lower side. 



^ There are 14 dorsal vertebræ, according to Duvernoy. 



" The newspapers mentioned that, in the summer of 1860, a specimen of this species was caught 

 on the coast of Bohuslan (Sweden), and had been purchased for the museum of the college in 

 Orebro. It was, however, D. Phocæna, according to later information given me by Lector 

 Hartraan.
