172 REPORT OF NATIONAL MUSEUM, 1884. 



main unpublished. Some 55 spefties uew to science were obtained by 

 this expedition, and the number of species of shore fishes known from 

 the Pacfic coast of California, Oregon, and Washington was raised from 

 about 200 to nearly 275. Series of specimens containing each from 50 

 to 250 of these species have been distributed to some 75 different mu- 

 seums, in various parts of the world. 



The most important result of our work on the Pacific coast is prob- 

 ably the solution of the problem as to the number of species of salmon 

 (Oncorhynchus) inhabiting the North Pacific. Similar results were 

 reached at the same time by Dr. T. H. Bean, who was then carrying on 

 explorations in Alaska. 



On my return to the East I visited Utah Lake. Here, with the assist- 

 ance of Peter Madsen, a fisherman at Provo, I made a considerable col- 

 lection of fishes, some of them new to science. These have been described 

 by Jordan and Gilbert in the Proceedings of the U. S. JSatioual Mu 

 senm, 1880, 459. 



After finishing his work in California in November, 1880, Mr. Gilbert 

 continued his explorations southward, spending the winter at Mazatlau 

 and Panama, returning from Colon to Washington in the spring of 1881. 

 A remarkably rich and carefully preserved collection was obtained from 

 the Pacific coast of Mexico and Central America. This included some 

 60 species new to science. These have been described in several papers 

 by Jordan and Gilbert in the Proceedings of the U. S. National Museum 

 and Bulletin of the U. S. Fish Commisson in 1881 and 1882. An elabo- 

 rate paper containing synonymy and detailed descriptions of all the 

 species of fishes known from the Pacific coast of tropical America was 

 prepared by us for publication. This was destroyed by fire in 1883 when 

 nearly ready foi- the press. 



1881. 



The summer of 1881 was spent in Europe. Collections were made in 

 Genoa and Venice. 



1882. 



In the spring of 1882 1 visited Galveston, New Orleans, and Pensacola, 

 making a considerable collection at each point. The most important 

 part of this collection was that obtained at Pensacola, with the assist- 

 ance of Mr. Silas Stearns. The collections of fishes made by Mr. Stearns 

 at Pensacola are among the most important which the National Museum 

 has received from any source. The results of this expedition were pub- 

 lished by Jordan and Gilbert in the Proceedings of the U. S. National 

 Museum lor 1882, pp. 241-307. 



Part of the summer of the same year was spent by Professor Gilbert 

 at Charleston, S. C. In his work here Professor Gilbert received im- 

 portant aid from Mr. Charles C. Leslie. The results of his explorations 

 were published by Jordan and Gilbert in Proceedings of the U. S. Na- 

 tional Museum, 1882, pp. 580-620.
