pices, are also very large. Other collections made by the commission 

 consisted of series of the fresh-water fishes of the Columbia and Clack- 

 amas rivers of Oregon, and the McCldud Eiver of California, gathered 

 by Mr. Livingston Stone ; of landlocked salmon, and other fishes of 

 Grand Lake Stream, Maine, by Mr. Charles G. Atkins; and a great 

 variety of sea-fishes from Wood's Hole, Massachusetts, by Mr. Vinal N. 

 Edwards, and of the Saint John's River, Florida, by Messrs. Baird and 

 Milner. 



A large number of the stomachs of mackerel, collected by Capt. H. C. 

 Chester, furnished the means of solving an important problem in regard 

 to the food of that fish. Collections were also made at various points 

 by Mr. Milner and his assistants of the Commission. Mr. Samuel Powel, 

 of Newport, who has been engaged for several years in collecting the 

 fishes of his vicinity, has added many specimens to those already pre- 

 sented by him to the museum, and furnished much information in 

 regard to the geographical distribution of species. 



Captain Hulbert, who was engaged as pilot on the Speedwell during 

 her summer's cruise, obtained and transmitted a new species of chi- 

 mrera, which is now named C. plumbed by Professor Gill. This was 

 ^aken on a halibut line, at a depth of several hundred fathoms', off the 

 coast of Nova Scotia. 



Mr. E. G. Blackford, the well-known fish-dealer of Fulton Market, 

 New York, has continued his valuable contributions, that have now ex- 

 tended over a number of years, securing and supplying to the museum 

 all the rarer and more remarkable fishes received by the New York 

 dealers. A large number of specimens have been sent by him, as enu- 

 merated rii the list of donations, and furnishing a continued illustration 

 of that public spirit, liberality, and disinterestedness for which we are 

 happy to make a public acknowledgment. 



Many specimeus of various food-fishes, as salmon, trout, whitefish, 

 and the like, have been sent by different contributors for the purpose of 

 meeting an expressed want or of securing identification. 



A very interesting series of contributions during the year has con- 

 sisted of specimens showing the success of the various efforts made un- 

 der the direction of the United States Fish Commission for the propa- 

 gation of food-fishes and their introduction into new waters. Among 

 these may be mentioned a full-grown, true shad caught in the Ohio 

 River at Louisville, being one of six hundred taken during the summer 

 under similar circumstances. These were probably derived from the 

 stock introduced four years previously as young fish into the Allegheny 

 River in Western New York. This was presented by the fish commis- 

 sioners of Kentucky through Mr. Pack Thomas. 



A shad, also the result of the transfer of young fish to California sev- 

 eral years ago from the East, was furnished by Mr. Bassett, through Mr. 

 B. B. Redding. The latter gentleman also supplied several specimens 

 of the food-fishes of the Sandwich Islands, of which living specimens
