the surface of the Uver, the female after this is complete dies and 

 disappears. 



In another shark of the same species the same eggs were found in 

 lines on the lighter colored portions of the anterior edges of the fins. 

 Since they have not appeared in any other species of shark, I have 

 named them as deposited by a member of the genus Capillaria^ which 

 should be called Capillaria carcharhini^ new species. Although the 

 other members of the genus are well known in other animals, this is 

 possibly the only one recorded as having been found in a fish. 



The type specimen has been deposited in the United States 

 National Museum, Helminthological Collections under the number 

 7812.
