here described. It is not, however, only on the number of the phalanges that the extra- 

 ordinary difference in the length of the fins of these two forms depends; the shape of the 

 individual phalanges also contributes its share to this effect, being comparatively much longer in 

 the ca'ing-whale than in our species, in which, indeed, theii- length still surpasses their breadth 

 in the first three fingers, but the difference between the two dimensions is, nevertheless, only 

 small. The dolphin here treated of stands in this respect about midway between the Globio- 

 cephali and the Orcas, in the latter of which the breadth exceeds the length of the phalanges, 

 even in the two longest fingers ; but as to the number of the phalanges, it approaches the latter 

 more than the former ; for in an old male Orca, from the Kattegat, I count two, seven, four, 

 three, and two phalanges ; but in spite of the resemblance, in this respect, the shape of the 

 pectoral fin is (as we have said) extremely different also from that of the Orca. Cuvier states^ 

 the number of the phalanges of Belpldnus grisens to be two, eight, seven, two, and one ; if no 

 errors have slipped into this statement, we are almost forced to believe that the phalanges of 

 this dolphin are comparatively longer even than those of the Glohiocephali, and accordingly as to 

 their shape still more different from those of our dolphin than those of the last-named genus ; for 

 as we shall see presently, this Belpldnus r/riseus, remarkable in several respects, but the 

 description of which, we are sorry to say, is only rather superficial, must have comparatively 

 longer, though, at the same time, broader pectoral fins than the caring-whale ; and it is not 

 probable, that their great length is in any essential degree owing to an unusual length of the 

 bones of the fore-arm.
