PARASITIG COPEPODS OF THE ZOOL. MUSEUM, KRA. 109 



in company with Gecrops and Orthagoriscicola, and hence 

 the present specimens furnish both a new host and a new 

 locahty. 



EcMhrogaleus coleoptratus (Guérin). 



A single female was found in company with the second lot 

 of the preceding species on the dorsal fin of Squalus acanthias 

 at Newfoundland. 



Caligoida, — Dichelesthiidae. 



Dichelesthium shirionis Hermann. 



A single, hadly mutilated female was obtained from and 



unknown host and locality. Since the only host thus far recorded 



for this species is some one for the sturgeons it would seem as 



if this specimen must have come from the same source. 



Lernaeopodoida — Lernaeopodidae. 

 Charopinus dentatus Wilson. 

 Seven females and one male were taken from the gill arches 

 of Raja binoculata at San Francisco. A second lot of eight 

 females, a third lot of ten females, and a fourth lot of three 

 females were all obtained from the same host and locality, the 

 latter of which is new. 



Clavella uncinata (Müller). 

 Eight females of this species were obtained from an unknown 

 host and locality. A second lot of females was taken from the 

 pectoral fin of Lycodes frigidus 107 km. west of Beeren Island 

 during the Norwegian North Atlantic Expedition. A single 

 female was found on the gills of Gadus polaris from the 

 coast of Greenland. Even for such a cosmopolitan from as this 

 species we have both a new host and a new locality.
