 graphs of the shark, was sent. — W. G. S. 



BRITISH MUSEUM. — (NATURAL HISTORY.) 



Cromivell Road, South Kensington, S. W., 15.5. '84. 



Dear Sir : I am truly obliged to you for your kind- 

 ness in sending me the photographs of the shark which, 

 with your description, leave no doubt that you have had 

 the extraordinary good fortune of obtaining a Car chart as 

 rondeletii. It is one of the most interesting discoveries 

 in Atlantic ichthyology. Although I have been endeav- 

 oring for years to get a specimen, I have been unsuccess- 

 ful hitherto. 



Believe me, yours very truly, 



A. Gunther. 



Dr. W. G. Stevenson. 



On the same evening the. following description was 

 given of 



Odontaspis littoralis — sand-shark ; shovel-nose. 



BY W. G. STEVENSON, M.D. 



Odontaspis littoralis — (Mitch.) J & G. 



[Syn. — Squalus americanus (Mitch). Squalus littoralis 

 (Mitch). Carcharias griseus (Storer). Odontaspis ameri- 

 canus (Gunther). Eugomphodus littoralis (Gill). Car- 

 charias littoralis (De Kay) — ]. 



The second shark which I have the pleasure of present- 

 ing to the Institute this evening was also taken, by Mr. 

 C. B. Herrick and myself, on the fourth day of August, 

 1883, about two miles off Great Point light-house, Nan- 

 tucket, Mass. 



Its perfect skin and large size, for this species, make it 

 desirable to place its description on record. 



It is a common species in American waters — at least 

 along the Atlantic sea-board — and is known as 



Odontaspis littoralis, — Sand-shark.
