I. '21. 32 



Size. — In the largest specimen taken by the Helga (from 

 S. R. 321), the carapace is 20-5 mm. long, and the propodite 

 of the large cheliped measures 20 mm. The propodite of 

 Hansen's largest specimen (1908), taken in the Onundar 

 Fjord, on the north of Iceland, was 31 mm. long. 



General Distribution. — The species is known from the 

 Shetlands and the Hebrides (Norman), and extends along 

 the west coast of Scotland into the Irish Sea (Walker), and 

 to the south-west of Ireland (Pocock). On the east coast 

 of Great Britain it has been taken at Peterhead (Metzger), 

 at the Bell Rock, Holy Island, Sumburgh Head and Spurn 

 Point (Tesch), the Firth of Forth (Scott), Northumberland 

 (Meek). It does not extend farther south than Durham 

 (Norman). It has been recorded from the Skagerak and 

 Kattegat (Meinert), and from stations along the whole west 

 coast of Norway (Sars). It rounds the North Cape, and is 

 found in the Murman Sea (Birula) and the White Sea, and off 

 Nova Zembla at Jugor Schar (Hansen) and Matotschkin 

 Schar (Stuxberg). It is not known as yet from the Kara 

 Sea or the north coast of Siberia. It occurs at Spitzbergen 

 (Doflein, Ohlin), and at Bear Island (Sars). It is common 

 at the Faeroes and all round Iceland (Hansen). On the east 

 coast of Greenland it is very rare, but has been taken at a 

 large number of stations on the west (Hansen, Stephensen). 

 On the east coast of North America it is found off Labrador 

 (Smith), in the Gulf of St. Lawrence (Smith), Newfoundland 

 (Milne-Edwards and Bouvier), Nova Scotia, and southwards 

 along the coast of the United States to 37° 8' N.L. It has 

 been recorded from Kamchatka (Brandt). 



Hansen (1908) thinks it very probable that E. trigonocheirus 

 Stimpson, belongs to the same species, in which case its range 

 is extended to north and north-west Alaska. He holds the 

 same view with regard to E. capillatus, Benedict, E. Brandti, 

 Benedict, and E. Dalli, Benedict, which have been taken off 

 Alaska, the Aleutian Islands, Unalaska, and in the Behring 

 Sea. 



The geographical distribution is boreal-arctic rather than 

 arctic, as the species is apparently absent from the Kara Sea, 

 Jan Mayen, and Franz Josef's Land. 



Vertical Distrihutio7i. — It has a considerable range in depth, 

 being known from 2 fathoms down to nearly 600 fathoms. 



Irish Distribution. — The species is mentioned by Kinahan 

 in his lists of Crustacea from Dublin and from Belfast. Walker 

 records it from the Irish Sea to the west of the Calf of Man, 

 and Pocock from 200 fathoms off the south-Avest coast. 

 Farran mentions it in the list of Decapods from Clare Island, 

 Co. Mayo, and there is a specimen in the National Museum, 

 from Bray Head, near Valentia, County Kerry (23 fathoms). 

 The Helga has taken it at several stations, notably off Howth 

 Head and near Rathlin Island. It was also taken at a station 

 iifty miles off Mayo, and at four points off the south-west coast,
