Clavella parva Wilson. 

 A single female was taken from the gills of a species of 

 Sebastes at San Francisco, which is a new locality. 



Parahrachiella rosirata (Krøyer). 

 A single female of this species was taken from an unknown 

 host on the coast of Greenland. This species is common upon 

 the halibut of the northern Atlantic and has also been taken 

 from some of the large flounders. 



Naohranchia occidentalis Wilson. 

 Four females were found on the gills of a species of Sebastes 

 at San Francisco, California. The orginal specimens of this 

 species came from the gills of the Pacific cod and from the 

 shores of Alaska. The present material came from a new host 

 and a new locality. 



Lernaeopodoida — Chondracantliidae. 



Chondr acanthus cornutus (Müller). 



A single female was taken from the gills of an unknown 



host on the coast of Greenland. This is a very cosmopolitan 



species and has been found chiefly upon the flounders and their 



close relatives. 



Caligoida — Lernaeidae. 



Pennella sagitta (Linnaeus) 



A single female was taken from the flesh of Antennarhis^ 



pictus in the Sargasso Sea by Edward Dies. Linnaeus's original 



specimens came from the sargassum fish and so from the same 



locality, but the present host is a new one.
