3.— OBSERVATIONS UPON FISHES AND FISH-CULTURE. 
Materials of the kind included in this article have heretofore appeared in the 
report of the Division of Fish-Culture and have been published as a part of the Commis- 
sioner’s Report. They are derived almost entirely from the reports of the superin- 
tendents of the stations and officers in charge of vessels of the Commission, and the 
language of the authors is preserved as nearly as possible. From the nature of the 
paper, arranged as it is by species in their zoological order, it would be difficult to 
indicate the authority for each item, but a list of the persons from whom information 
has been obtained is given below, together with the names of the stations or vessels 
furnishing the scene of their observations. The notes have been arranged for publi- 
cation by the editor of the Commission, Dr. Tarleton H. Bean.

Sawfish (Pristis pectinatus) . 
A sawfish, measuring 15 feet 4 inches and weighing about 600 pounds, was 
taken at San Carlos Bay, Fla., by the steamer Fish Hawh, on March 22, 1889. The 
skin was prepared in a very skillful manner by the surgeon of the vessel, Dr. C. B. S. 
Adams, and was presented to the U. S. National Museum. A female was also sur- 
rounded by the seine, but escaped before the haul was landed. It was supposed that 
the pair had approached the shore for breeding purposes. The bottom upon which 
they were found was covered with fine white sand, intermingled sparsely with small 
shells, chiefly scallops.
