360 ' TENTACULATED SHARK. 



along the edges in a singular manner ; three or four 

 or more of the smaller ones being interposed be- 

 tween each of the larger and longer ones : the total 

 number on each side is not less than ninety-two or 

 ninety-three : a row of small and distant spines also 

 runs along the under part of the edges : at about 

 the middle of the snout beneath, from each side, 

 springs a long and flexible tentaculum or feeler, of 

 a flattened shape, gradually tapering to the tip, 

 and appearing covered entirely, if closely inspected, 

 by minute scales of similar structure to those with 

 which every other part of the skin is clothed : 

 these scales are of a somewhat triangular shape, of 

 a lucid surface, and marked by a small carina or 

 midrib: the mouth is placed beneath the head, as 

 in other Sharks, and the teeth, which are of mo- 

 derate size, subtriangular, and sharp-pointed, are 

 disposed in five rows in each jaw : the dorsal, 

 pectoral, and ventral fms are disposed as in most of 

 the slender-bodied Sharks, and the tail is of similar 

 structure, viz. slightly bilobate at the tip, the fin 

 or lobe being broader and continued to a greater 

 distance beneath than above.
