LAOPHONTE. 75 



(fig. 8) very long, with a long and slender 2-jointed 

 peduncle, the margins of which are densely ciliated ; 

 outer scarcely one third as long as the first joint of 

 the inner branch; inner branch stout and strongly 

 clawed. Second, third, and fourth pairs shorter, 

 slender, outer branches about twice as long as the 

 inner, densely ciliated on the external margins ; apical 

 spine of each joint very long and pectinated on the 

 edges ; first joint of inner branches very short, second 

 long and slender. Basal joint of the fifth foot very 

 large (fig. 10) ; segments much elongated, the outer 

 bearing one, the inner four long setae. Length ^jth of 

 an inch (1-3 mm.). 



This remarkable and strongly characterized species 

 has been noticed in Britain as yet only on the 

 Atlantic coasts of Scotland and the north of Ireland, 

 but was found also by the German Polar Expedition in 

 the Arctic Sea. Buchholz, in his account of the 

 Zoology of that Expedition, refers it to Cyclops minuti- 

 cornis, Muller, an identification which certainly cannot 

 be accepted, and Mr. Norman in his report on the 

 Crustacea, &c., of the " Valorous " cruise, proposed 

 for it the specific name horrida, a term which I had 

 also myself previously applied to it, though only in 

 MS. My collection contains several specimens which 

 were dredged off the Island of Cumbrae amongst vege- 

 table and other debris, and one from a depth of fifteen 

 fathoms off Portincross (Ayrshire). Mr. Norman 

 found a single example in material from Oban, and, 

 lastly, I have noticed it in material washed from the 

 roots and fronds of Laminarice. in Mulroy Lough,
