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. Sabi?ii and the smaller British specimens (varying from 

 3 to 4-J- lines in length), certainly occurs in the large 

 specimens of A. Sabini. 



It was first taken by Admiral Ross and General 

 Sabine, in Baffin's Bav. 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
