A parasitic aruphipod, apparently quite identical with this species of 

 Europe, was found in the mouth of a goose-fish (Lopliim Americanus) 

 taken in Vineyard Sound. A species, apparently the same, was also 

 taken from the back of a skate (Raia lewis) 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. N. Ed- 

 wards. It is abundant, in company with Calliopius Icevimculus, about 

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

 dor and Greenland.

GAMMARUS ANNULATUS Smith, sp. uov. (p. ;JU.) 



Anterior margin of the head produced each side beneath the an ten - 

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

 ornatus ; eyes scarcely reiriform, less elongated than in G. ornatw, and 

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

 of the truncated lobe. Antennae longer than the antennuku ; the ulti- 

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

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

 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
