FISHES OF SINALOA. 379 



Mr. Gilbert spent six weeks at Mazatlan where he secured 

 a collection of about i8o species, of which number about 

 fifty were new to science. These were described by 

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

 tional Museum in 1881, the typical specimens being de- 

 posited in the Museum at Washington. Previous to this 

 time a number of specimens had been sent, by collectors 

 who had visited Mazatlan and Altata, to the Museum at 

 Vienna, where they were described by Dr. Franz Stein- 

 dachner, and to Berlin where they were recorded by Pro- 

 fessor Peters. 



Subsequent to the visit of Dr. Gilbert, collections were 

 made at Mazatlan and Presidio by Mr. Alphonse Forrer, 

 now of Santa Cruz, California. Most of these were sent 

 to the U. S. National Museum, where they were described 

 by the present writer. A few specimens were also sent 

 to the British Museum. 



In December, 1894, through the kindly interest of Mr. 

 Timothy Hopkins of Menlo Park, California, and under 

 the auspices of the Hopkins Seaside Laboratory, a branch 

 of the Leland Stanford Jr. University, an expedition 

 was sent to Mazatlan for the purpose of collecting fishes. 

 This was in charge of David S. Jordan, assisted by George 

 B. Culver and Edwin C. Starks. In addition, Mr. 

 Thomas M. Williams, Mr. Norman B. Scofield and Mr. 

 James A. Richardson accompanied the expedition as vol- 

 unteer assistants, with Frank H. Lamb as botanist, and 

 Mr. George B. Seward as herpetologist. 



One month, Dec. 24, 1894 ^^ Jan. 25, 1895, was spent 

 at Mazatlan in the collection of fishes. One hundred 

 and eighty-five species were obtained, of which twenty- 

 nine seem to be new to science, besides two species from 

 La Paz. A full series of the specimens obtained is in the 

 Museum of Leland Stanford Jr. University. Other series
