LERNiEA LUSOI. 145 



brassies or whiting-pouts, Gadus luscus (Linn.). Found 

 on the gills of this species of fish at Plymouth 

 (Bassett- Smith). Found on the gills of a brassie cap- 

 tured 10 miles off Aberdeen in January 1901 (T. Scott). 

 Frequent on the gill-arches of brassies, Irish Sea (A. 

 Scott). 



A Gad us luscus sent from the Fish-Mai-ket at Aberdeen 

 had one of these parasites adhering to it; in this example 

 the head of the parasite was buried in the tissues in the 

 abdominal region, behind and a little below the base of the 

 pectoral fin — a somewhat unusual position for a Lemfea.
