SOME DIGENETIC TREMATODES, INCLUDING EIGHT 



NEW SPECIES, FROM MARINE FISHES OF 



LA JOLLA, CALIF.^ 



By Harold W. Manter and Harley J. Van Cleave 



In April and May, 1940, one of us (Van Cleave) carried on a 

 preliminary investigation of the worm parasites of marine fishes 

 of southern California. The Scripps Institution of Oceanography, 

 through its director, Dr. H. U. Sverdrup, very generously pro- 

 vided facilities, and Dr. Denis Fox extended privileges of his 

 laboratory, while Percy Barnhart aided in the collection and 

 identification of the fishes. In the vicinity of La Jolla approxi- 

 mately 200 individual fishes were examined, representing 34 

 species. Two papers have been published previously on the Acan- 

 thocephala encountered (Van Cleave, 1940, 1945), and another 

 is in preparation. The present report is based wholly upon the 

 digenetic trematodes recovered from 16 species of fishes, but in 

 some instances the trematodes were either immature or so few as 

 to render identification impossible. Several of the hosts from 

 which no trematodes were taken were represented by one or a 

 very few autopsies ; consequently for these hosts the negative rec- 

 ords are without significance. More extensive sampling would be 

 needed before a faunal list approaching completeness could be 

 presented.
