Js^OTE ON ICICHTHYS LOCKINGTONI JOED AN AND GIL- 

 BEKT, A PELAGIC FISH FROM CALIFOENIA. 



By David Starr Jordan, 

 Of Stanford University, California. 



In the year 1880, while investigating the fish fauna of California 

 with my colleague, Dr. Charles H. Gilbert, a very peculiar fish of 

 uncertain family was placed in our hands. It was secured in the 

 market of San Francisco, from off Point Reyes, by W. G. W. Har- 

 ford, curator in the California Academy of Sciences, and described 

 by us ^ as Icichthys lockingtoni. The specimen, in bad condition, 

 was inadequately figured in the Oceanic Ichthyology of Goode and 

 Bean, the figure (No. 226) being copied by Jordan and Evermann, 

 Fishes of North and Middle America (fig. 406). The type was de- 

 posited in the National Museum (Cat. No. 27397). 



In July, 1922, a second specimen 18.05 cm. (7^ inches) long, was 

 received from a Monterey fisherman by Dr. Walter K. Fisher, di- 

 rector of the Hopkins Marine Station of Stanford University at 

 Pacific Grove. This was reported as one of 8 or 10 found swimming 

 at the surface under the disk of a large jelly fish supposed to be 

 Pelagia. The fish was unlmown to its captors, who saved one speci- 

 men, throwing the others away. 



Of this example, 18.05 cm. (7^ inches) in length, I present a new 

 figure and a description.
