CRUSTACEA MALACOSTRACA. III. 177 



as the section Ancinini among the Sphaerominae platybranchiatae. That the first pair of pleopods are 

 uniramous is only a very interesting generic character, which besides ought to be recorded as an 

 exception in the characterization of the whole family as given p. 97—98 in my paper quoted. 



Only two species of this very rich family have hitherto been found in the "Ingolf" area, and 

 they belong to two sub-families, viz., the Limuoriinae and the Sphaerominse. 



Limnoria Rathke. 



Only one species is known from our area.

Occurrence. Not taken by the "Ingolf. But some specimens have been captured by Dr. 

 A. C. Johausen at Reykjavik, west coast of Iceland; besides, I have seen a good number of specimens 

 secured by Cand. mag. Saemundsen at Iceland, and probably also near Reykjavik. — It occurs at the 

 Faeroes, as the Physician F. Jorgensen has presented the Zoological Museum with a piece of wood 

 containing many specimens and found at Trangisvaag, 1 — 3 fath. 



Distribution. Taken in the Kiel Bay, at places on the east coast of Jutland, at the west 

 coast of Sweden near Goteborg, in Christiania Fjord and at the Lofoten Island; at Great Britain, Hol- 

 land and France; in the Adriatic and the Black Sea (various authors). Furthermore known from the 

 east coast of North America from the Gulf of St. Lawrence and Halifax (Nova Scotia) to Florida, and 

 H. Richardson has also put together information on its occurrence at the Bering Island and at San 

 Diego, California. Tattersall has seen a specimen from Port Stanley, Falkland Islands, and Stebbing 

 recorded it from Port Elisabeth in South Africa. Chilton has seen specimens from Auckland harbour, 

 Lyttelton and Akaroa harbours, and he says that Whitelegge recorded it from Sidney and another 

 Australian locality. Chilton's opinion that it has been introduced into such harbours in the southern 

 hemisphere by wooden vessels is certainly correct. 



BathyCOpea Tattersall. 



Description. Body much depressed, expanded laterally and broadly oval. — The head some- 

 what small. Eyes, if present, very small, feebly developed and a little removed from the margin of 

 the head. — Autennulae inserted on the front end of the head ; their basal joint (PI. XIV, figs. 7 a and 

 7 b) much produced as a large plate almost as broad as long and entirely visible from above; third 

 joint long and slender; flagellum with more joints in the male than in the female. Epistome (fig. 7 a) 

 produced into an oblong-triangular process reaching about to the middle of the inner margin of first
