SCANDINAVIAN CETACEA. 233 



stranded on a shoal in the vicinity of Ronneby in Blekinge (Sweden) in the spring of 1851, and I have 

 therefore been fully justified in quoting Professor Nilsson's remarks about this dolphin, in the synonymy, 

 as they have reference to the same specimen. 



The male that, according to Banks and Lacépéde, was captured in the Thames in June, 

 1793, was 31' (Enghsh) long; and the specimen found near Ronneby was 24' (Swedish). 

 The one described by Gunnerus was 24' (Norwegian) in length, the same as the one 

 described by Hunter. I have seen two skulls from Christiania, from specimens caught in the 

 bay there, and stated to have been about 25' long. This length seems, consequently, to be the 

 most common. The form of its body has not yet been exactly described ; but the skeleton, being of 

 a heavier structure than in the following species, leads us to suppose that it is still more robust 

 than the latter, although there is not much difference between them in this respect, in consequence of 

 being two species so nearly related to each other. The Norwegian fishermen state, as I have 

 mentioned, that its dorsal fin is considerably higher than in the succeeding species, viz., 4' — 6'. From 

 the short description of its colour given by Nilsson, at the place cited, it seems that it resembles 

 that of the succeeding species, with the exception that it has a rounded white spot on the neck, 

 and not any purple streaks on the back near the dorsal fin. As this spot is not mentioned by any 

 other author it is certainly possible that it may be an individual deviation in colour; but as the 

 colours of the whales generally seem to be very constant, I have considered it due to mention it 

 as deserving attention. 



Skeleton. — Entire length about 21' 6"; length of skull 3' 6". Its width over the 

 anterior dilated part of ossa zygomatica at frontis 1' 9". Length of nose 1' 9" ; its width at the 

 base 1' ir. Teeth line in the upper jaw 1' %f long. Length of lower jaw 2' 8^"; its row of 

 teeth r 3i". Body of atlas 8r wide and 6" high. Body of the 2nd lumbo-sacral vertebra 5^" 

 wide, and its transverse processes 6" long. Body of the 10th, or penultimate lumbo-sacral 

 vertebra 6," wide, 6i" high, and 5" long ; distance from body to the point of spinous process Bg". 

 The longest ribs are in a straight line, 3' 2" — 3" long. Length of scapula, from the glenoid 

 cavity to the upper opposite edge 1' 4i", and its width 1' lOi". The acromion is subquadrangular, 

 4j" long, and somewhat more than 4" wide. Processus coracoideus 3~" long. Os humeri 10" long 

 and 7" wide at the lower end. Its tuberculum majus is very large, and head directed almost 

 straight to the side. Radius 1 1" long and S^" wide at the lower end. Ulna 9" long, 5" wide 

 across the olecranon, and 6i" across the lower end. Ossa pelvis 1 1" long, in a straight line, and 

 somewhat curved. The teeth 12 — 13 in number, on each side of the upper and lower jaw, 

 short and thick, with the points worn down ; the larger ones are U" in transverse diameter. 

 The nasal and frontal bones form a high tuberosity behind the blowers. The triangular area 

 on the intermaxillary bones in front of the blowers is slightly concave, and divided along the 

 middle by the inner edges of these bones rising there. The three foremost cervical vertebræ are 

 united by their bodies, and they are all, except the 7th, united by their spinous processes. 

 Behind the strong lateral processes of the atlas there are a pair of smaller, but still quite large 

 lateral processes that seem to belong to the axis, which is ankylosed with the atlas. The processus 

 transversi of the 3rd cervical vertebra form a ring. Dorsal vertebrae 12, lumbo-sacral vertebræ 

 11, caudal vertebræ 24,^ and, consequently, with the addition of the 7 cervical vertebræ, in all 



^ The caudal region is here, as always, counted from tlie beginning of tlie processus spinosi inferiores
