DOLPHINS. 243 



72. DELPHINUS DELPHIS, L. Gomfarad Delfin. The Com- 



mon Dolphin. 



Nose small and long ; longer than any other dolphin ; 

 teeth 43 to 50 on each side of the upper and lower 

 jaws ; skin smooth, glossy. Colour, above grey-black ; 

 below white. Length 6 to 8 ft. j dorsal fin, 9 to 10 in. 

 high; pectorals rather longer; tail 12 in. broad. 

 Rare in these seas. 



I may here remark that the fish to which sailors com- 

 monly give the name of the dolphin is not this, but a true 

 fish, the Coryphcena Hippuris, L., celebrated for its swift- 

 ness in swimming, and its brilliant and beautiful colours. 



73. D. EUPHROSYNE, Gray, Fin Tandad Delfin. 



Gums without a furrow ; teeth in a bent row, 42 to 

 46 in each jaw, very small, pointed, crooked; 6 to an 

 inch along the nose, the length of which is equal to 

 three times its breadth ; a half round rib, with vertical 

 sides. Length of the skull 16 in. 4 L; nose 10 in. 4 1. 

 Skulls of this and the next species are deposited in the 

 Lund Museum, supposed to have been taken in the Cattegat. 

 Rather a loose authority for giving either of these species 

 a place in the Scandinavian fauna. 



74. D. OBSCURUS, Gray. Delfin med rata Tandrader. 



Teeth in a straight row ; 30 to 32 in each jaw ; 4^- to 

 an inch; length of the skull 15 in.; nose 8 in. 6 1. 



75. D. LEUCOPLEURUS, Rasch. Hvitsidig Delfin. (The 



White-sided Bottle-nosed Dolphin.)

 double as long as it is broad ; length 6 ft. 1 in. ; nose 

 8 in. 6 1. ; colour above blue-black ; below white, with a 

 large oblique grey longitudinal streak on the hinder 

 part of each side. 



Is rarely met with in the Cattegat ; more frequently on 

 the Norwegian coast, in large flocks.
