UNITED STATES 



fish is rare in this part of America. 'The whole 

 length of the body and tail was thirteen feet and one 

 inch. The skin, though thick as that of the common 

 shark, was not at all rough, except a very little on 

 the back. The colour was dusky or brown, and the 

 shades darker on the upper side than on the belly. 

 The tail was stout and elastic. Its superior edge 

 was about three or four inches broad, and tapered 

 away to nothing below. In this respect it had some 

 resemblance to the fin of the sea tortoise. The 

 teeth were very sharp, of about three fourths of an 

 inch long, and formed but one row. The body was 

 very cylindrically formed, and possessed the great 

 general features of the shark family. A cut of this 

 fish is given in the Medical Repository, Hexade 2d. 

 vol. 2. 



Dr Mitchell, to whom we are much indebted for 

 his investigations on many subjects connected with 

 the natural history of the United States, has also 

 given us an interesting account of the structure and 

 functions of the foetus of a species of shark found on 

 the coast of New York during the summer months. 

 About nine years since, while he was engaged in a 

 fishing party in one of the bays on the south side of 

 Long Island, a shark between four and five feet in 

 length was taken in the seine, and upon examination, 



t)ie Monthly Magazine of London, for August last, by Mr, Bingley, of 

 a thresher shark, squalus vulpes. Linn, caught on the British coast, 

 in which the largest of the teeth was a quarter of an inch long, they 

 were also triangular, and ranged in three rows in front of the upper, 

 and four rows in front of the lower jaw The upper parts of the 

 body are cinereous, and blue under, with ash coloured spots, ...Manjr 

 more marks of difference might be mentioned.
