ART. 21 A NEW CALIFORNIAX SURF-FISH HUBBS 5 



hoelzi) . This false synonymy, persisting until my correction in 1928, 

 gave rise to a bad error in statement of ranges: Holconotm rhodo- 

 terus was said to range northward only to San Francisco, whereas 

 it is abundant along the surf of Oregon and Washington, and 

 Amphktichus argenteus was said to range northward to Cape 

 Flattery, whereas there are no authentic records north of San 

 Francisco. 



The range of Crossochir koeisi, as determined from the literature 

 records and from the type specimens, is central and southern Cali- 

 fornia, from Drakes Bay to San Diego, and thus approximately coin- 

 cides with that of Ainphistichus argenteus and overlaps that of Hol- 

 conoi/us rhodoterus about San Francisco. So far as checkable, all 

 records of H. rhodoterus from south of San Francisco were based on 

 Crossochir koeJzi. What little is recorded as to its habitat indicates 

 that this species, like its nearest relatives Holconotus rhodoterus and 

 Amphistkhus argenteus^ is essentially an inhabitant of the surf, 

 ordinaril}' penetrating the bays only to their more open portions.
