No. XII.— A PRELIMINARY REPORT ON THE FISHES COLLECTED BY THE 

 STEAMER ALBATROSS ON THE PACIFIC COAST OF NORTH AMERICA 

 DURING THE YEAR 1889, WITH DESCRIPTIONS OF TWELVE NEW GENERA 

 AND NINETY-TWO NEW SPECIES. 



BY 

 Charles H. Gilbert, 



Professor of Zoology, University of Indiana. 



The investigations of the Albatross during the year 1889 extended 

 over the following regions : 



(1). The coast of California south of Point Conception, together 

 with the outlying islands (stations 2891 to 2982). 



(2). The Revillagigedo Islands, Clarion, Socorro, and San Benedicto 

 (stations 2991 to 2995). 



(3). The Gulf of California and the western coast of Lower Califor- 

 nia (stations 2996 to 3045). 



(4). The coasts of Oregon and Washington (stations 3046 to 3076). 



The shore fishes of California, Oregon, and Washington were already 

 well known, and the new discoveries from these regions were almost 

 wholly from greater depths than 50 (from 50 to 1000) fathoms. 



From the Eevillagigedos not more than a dozen species in all had 

 been previously recorded. Of the sixty obtained from shallow water 

 during our short stay not more than half are yet known from the 

 neighboring mainland, the other half, including, together with new forms, 

 a number of strays from the islands of the Western Pacific and from 

 the Galapagos. 



The collections from the Gulf of California were obtained mainly 

 along the shores and in the shallower waters of its northern portion ; 

 the deeper waters of the Gulf having a bottom of blue mud singularly 

 barren of life. 



The present paper deals only with the new forms obtained on tlie 

 cruise, and will be followed by a more extended report.
