GAMMARIDiE. 
A . Sabini, under the name of G. angulosus , which may, 
possibly, be a variety of the former. He, however, 
gives among its specific characters, the rostrum obtuse, 
the upper antennae shorter than the lower, the carina 
wanting in the four basal segments of the tail, the upper 
surface of the thorax angulated, and the middle tail- 
scale as broad (oblong-quadrate), and posteriorly sub- 
emarginate. The majority of these characters would 
apply to the young of such an animal as A . Sabini, 
whilst the ridge on each side of the dorsal carina, which 
has been relied upon as the chief distinction between 
A. Sabini and the smaller British specimens (varying from 
3 to 4|- lines in length), certainly occurs in the large 
specimens of A. Sabini. 
It was first taken by Admiral Hoss and General 
Sabine, in Baffin’s Bay. It has been since taken at 
Godthad, on the coast of Greenland, in about sixty 
fathoms of water, by Herr Holboll ; Mr. Drewsen has 
captured it at Iceland ; Rathke and Dueben have found 
it in Norway ; Liljeborg on the eastern shores of Scandi- 
navia ; and Bruzelius says that it is common both in the 
German and Baltic Seas; the late Dr. Johnston for- 
warded fine specimens to us from Berwick Bay, where 
it is not uncommon ; and Mr. Byerley took it in the 
Mersey in 1854; Mr. Barlee has sent it to us from the 
Shetlands ; Mr. Edward from Banff ; and Mr. Hodge 
has taken it at Seaham, on the coast of Northumber- 
land ; Mr. Thompson records it as having been taken at 
Sligo ; and Mr. Stimpson states that he found it at 
Grand Manan, on the coast of the United States. 
Of the smaller individuals we have received speci- 
mens from the Menai straits, where they were dredged 
by Mr. Alder ; also from Dr. Walker, taken in the 
Mersey ; and recently Professor Kinahan has found it
