Ko.ies pacific coast copepods WILSON. 47;, 



This new species may be recognized by the abruptly narrowed 

 ends of the second maxillipeds, by the flattening of the genital por- 

 tion, by the position of the first maxillipeds, and by the slenderness 

 and length of the egg strings. These differences may then be con- 

 firmed by the structure of the various appendages.

LERN^EOPODA CALI FOKNI ENSIS Dana. 



LerncEopoda califomiensis Dana, 1852, p. 1379, pi. xcvi, fig. 1 a \<> i>. 



Host and record of specimens. — Dana's original types were taken 

 from the body of a salmon {Oncorhynchus) captured in the Klamath 

 River, California. In some manuscripl note- made by Dr. R. R. 

 Gurley, of the U. S. Bureau of Fisheries ( 1896), upon the Parasites 

 of the Fresh-water Fishes of North America, occurs the following: 



Some Bpeciinena of n Lcrntcopoda from the Columbia River basin appear n> 

 belong in this species, as far as it is possible to tell from Dana's brief descrip 

 tion and figure, whicb latter, being merely an outline, admits of 110 very satis 

 factory comparison. Four specimens were taken from the iniis of Oncorhyn 

 thus ncrka by Dr. 1'.. \v. Evermaun, in an inlel to Big Payette Lake, Idaho, 

 September i!T. 1894. It may lie noted thai ". nerka also occurs in Klamatb 

 River, from which Dana's types were obtained. 



The author ha- not -ecu the above-mentioned specimens and so 

 can only quote the authority given lor their identity with the present 



specie-.
