1914] Townsend: The Porpoise in Captivity. 299 



The appearance of the unborn young is well shown on plates 

 11 and 12. 



According to the statements of the Hatteras fishermen the 

 young porpoise nurses while the mother floats on her side ; when 

 very young it swims just ahead of the mother, and is raised to 

 the surface by her each time she rises to breathe. 



If our porpoises live long enough to breed in captivity, our 

 knowledge of whales in general and porpoises in particular will 

 be materially increased. 



The specimens now in the Aquarium were presented on 

 the beach at Hatteras, by Mr. Joseph K. Nye, of New Bedford, 

 Mass., the proprietor of the fishery. They were transported at 

 the expense of the New York Zoological Society. 



The writer is indebted to Mr. Nye, and to Mr. W. H. Rollin- 

 son, manager of the fishery, for the statistics of the catch pre- 

 sented herewith.
