found on the Coast of Yorkshire. 287 



It is described by the fishermen as sluggish and unwieldy in its move- 

 ments, and but seldom to be observed towards the surface of the 

 water. When they obtain specimens it is generally at a time when 

 they are fishing in deep water, and when the bait with which the 

 hooks are armed is near to the bottom. In this respect it resembles 

 the Scyllus, or Ground Shark. If we were to regard only its internal 

 organization we should be disposed to consider it as closely allied to 

 that genus." — Illustrations of the Zoology of South Africa, by Andrew 

 Smith, M.D., Part I. Pisces, pi. 1. 



After an attentive examination of the particulars on this subject 

 published in the Supplement to Mr. Yarrell's History of our British 

 Fishes, part ii. p. 54, I have no doubt that all the specimens, and the 

 various synonyms employed, refer but to one and the same species 

 at different periods of its existence. — A. S. 



Note. — Since the receipt of Mr. Arthur Strickland's communication, 

 the second portion of a systematic arrangement and description of 

 sharks by Drs. Miiller and Henle, published at Berlin, has been received 

 in this country, a reference to which appears to confirm the opinion 

 given by our friend that the various published accounts of a spiny shark 

 refer but to one species. The following are extracts from this valuable 

 German work, p. 91 : —

Examples stated to have been seen by the authors of the work : 



One in the Museum at Leyden ; one from the Cape by Dr. Smith. 



The coloured figure of this shark sent us by Mr. Strickland, so closely 

 resembles Dr. Smith's figure, as to make a second illustration unneces- 

 sary. — Ed.
