SCANDINAVIAN CETACEA. 239 



(Frencli). The dorsal fin was 3' long at the base, and 4' high (probably along the curve of the 

 anterior edge, and not in a straight line). The pectoral fins were long and narrow, 5' 2" long 

 and r wide. Width of caudal fin 4' 3". General colour, black, but beneath, from chin to anal 

 opening, white. The white colour extends in the shape of a heart under the chin and throat, from 

 which place the M'hite area suddenly tapers towards the tail. All the fins black. 



The skull is distinguished by the broad intermaxillary bones, by the narrow strip of 

 the maxillaries, visible at their outer edge, by the intermaxillary bones in front of the blowers 

 being concave' the greater part of their length, in consequence of the tuberosity formed by the 

 nasal and frontal bones behind the blowers being very high, and by the teeth lines being 

 very short, both in the upper and the lower jaw. The length of the skull is 2' 1", and its 

 width across the temporal bones 1' 5" on a skeleton 13' in length. The least vs^idth across pars 

 occipitalis II5", and the width across the orbits 1' 3~". Length of beak 1' 1", and its width at the 

 base 9|". Intermaxillary bones, together, 65" wide at the middle of the beak. Lower jaw 1' 7^" 

 long, and its row of teeth 6". Teeth of this skull |Z|, with indications that the 9th, on each side 

 of the lower jaw, had fallen out.* Dorsal vertebrae 11, lumbo-sacral vertebrae 13, caudal vertebræ 

 26 — 29 ; in all, with the 7 cervical, 57 — 60 vertebræ. Processus spinosi inferiores 17. The 

 sternum consists of three bones, the first of which has, on each side at its anterior end, a process 

 which is directed backwards. True ribs 4 pairs ; and the 5th and 6th pairs seem to have been 

 united to a cartilaginous extension of the sternum (processus ensiformis). 



The pilot-whale is very social, and is always found in shoals, either large or small. It occurs 

 in the North Sea, and the northern part of the Atlantic Ocean, sometimes even so far north as near 

 the coast of Greenland. It appears, at times, on the western and north-western coasts of Norway. 

 Such observations are mentioned in the " Skandinavian Fauna," and more recently it was stated 

 in the newspapers that some 2 or 3 years ago, a herd of 70 — 80 whales of small size had 

 stranded and been caught on the coast of Nordland, in Norway, which, from the description, 

 probably belonged to this species. It is said never to make its appearance in the Cattegat. 



"ård Genus. Phocæna, G. Cuvier. 



Nose short and obtuse or rounded, neither above nor behind limited by any conspicuous 

 notch. The opening into which the blowers are united on the upper side of the head is arcuate 

 and transverse, and placed almost exactly above the eyes, far behind the point of the snout. 

 Back with a fin about the middle of the body. Form of body robust, thicker and obtuse in front. 

 Both jaws armed with rather numerous teeth (20 or more) ; small, obtuse, and compressed at the 

 point. 



■^ The upper jaw appears in consequence of this, when seen from the sides, to be more depressed 

 and thin than in the preceding species. 



^ The number of teeth is variable ; 14 on each side above and 13 on each side below is said to be 

 the highest number; sometimes they are all lost in aged specimens.
