The personal observations recorded in this paper were made 

 between May 25 and July 28, 1910, and between May 13 and 

 July 15, 1911, while the writer was at work as investigator for 

 the United States Bureau of Fisheries at its laboratory at Beau- 

 fort, N. C. The fishes studied were in part collected by the 

 seining crew temporarily employed for the writer's work on the 

 gaff -topsail catfish, but the larger number, especially of the 

 rays, was obtained by visiting the drag-net fishermen up New- 

 port River, and particularly Messrs. J. E. Lewis and Charles L. 

 Willis of Morehead City, whose continued kindness it is a 

 pleasure to acknowledge. 



The observations recorded other than the writer's own are 

 chiefly those of Mr. Russell J. Coles, a sportsman of Danville, 

 Va., whose fishing experiences at and about Beaufort and whose 

 gifts of specimens to the laboratory cover nearly a decade. In 

 another paper of this series more definite mention and acknowl- 

 edgment of Mr. Coles' collections will be made. 



Carcharhinus (species unknown). 



< »n July 12, 1910, two small sharp-nosed sharks were taken at the Nar- 

 rows of Newport River. On attempting to classify them it was clear that 

 while they plajnly helonged to the genus Carcharhinus, it was equally 

 clear that as to species they were neither obacurus nor milberti, the forms 

 heretofore reported from Beaufort. Director Aller, to whom the classiti- 

 cation was referred, thought it a matter either of immaturity or of varia-
