A parasitic amphipocl, apparently quite identical with this species of 



Europe, was found in the mouth of a goose-fish {Lophius Americamis) 



taken in Yine^'ard Sound. A species, apparently the same, was also 



taken from the back of a skate (Uaia Icevis) in the Bay of Fundy the 



past summer. It is readily distinguished by its broad depressed form, 



and by having the third to fifth pairs of legs very stout and their distal 



segments forming powerful talon-like claws, while the first and second 



pairs are small and slender.

Taken at the surface in Vineyard Sound, in March, by Mr. V. K. Ed- 

 wards. It is abundant, in companj^ with Calliopius Iceviusculus, about 

 the Bay of Fundy in pools left by the tide, and ranges north to Labra- 

 dor and Greenland.

Anterior margin of the head produced each side beneath the anten- 

 nulse into a truncated lobe, which extends farther forward than in G. 

 ornatus; eyes scarcely reniform, less elongated than in G. ornatiis, and 

 their lower margins not reaching, by considerable, the anterior border 

 of the truncated lobe. Antenna? longer than the antennul^e ; the ulti- 

 mate segment of the peduncle longer than the penultimate ; the flagel- 

 lum much more slender, the segments more elongated and with fewer 

 hairs, than in G. ornatus. Hands of the first pair of legs more elongated 

 than in G. ornatus, and the palmary margins very oblique. Propodus in
