30 CRUSTACEA COPEPODA. II. 
land, not only parasitic on various fishes, but also rather frequently among plankton material. It is known 
from Bohuslan (Steenstrup & Ljiitken), from Kattegat and the western coast of Jutland (Kroyer), and has 
not unfrequently been taken by pelagic hauls in Skager Rak and the Kattegat (Bjorck). Brian records it from 
the Atlantic at Lat. 47°46’ N., Long. 5°40’ W., 132 m., on Raja, and from off Calvi, on Siphonostoma rotunda- 
tum; he says besides that it is common in the Mediterranean. It must be very common at the Atlantic coasts 
of the United States, as Wilson records it as taken on 25 species of fishes.

Of this large genus 4 species have been found in our area.

Occurrence. — Secured by the “Ingolf”’ at two localities. 
North-West Iceland: Isafjord, on the inner side of the pectoral fins of Pleuronectes limanda; 3 specimens. 
— —  Dyrefjord, on the skin of Anarrhichas lupus. 
This species has never been found at Greenland, but it has been secured several times by various 
collectors at Iceland on Pleuronectes platessa, Pl. limanda, Hippoglossus vulgaris and Gadus eglefinus, a single 
time and probably incidentally on Astevias rubens (Mag. sc. W. Lundbeck). The localities are: at North- 
West Iceland in Skutulsfjord, Onundarfjord and Dyrefjord, at West Iceland in Faxefjord, at South-West 
Iceland in Havnefjord, finally south of Iceland. 
At the Feeroes it has been gathered in Thorshavn on the fins of Pleur. platessa by Dr. A. C. Johansen. 
Distribution. — Firths of Forth and Clyde, Irish Sea, Belfast, and Plymouth (according to T. & 
A. Scott). At Bohuslan it was found on Pleuronectes flesus, and in Skager Rak on Raja radiata (Olsson). At 
Denmark very common, especially on the pectorals fins of various flounders (Kroyer).
