iF FISHES OF SINALOA. 379 
Mr. Gilbert spent six weeks at Mazatlan where he secured 
a collection of about 180 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.S Culver> and) Hdadwin Ci -Starks77) Im) :additionyt Mir. 
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 to 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 Lelar4 Stanford Jr. University. Other series
