Fifty to one hundred miles east of Tynemouth, Northumberland 

 (A. M. N.); Lough Foyle, Ireland, 15 fathoms (' Porcupine' Expedition). 



In Norway I have dredged it at Drobak in the Christiania Fjord, and 

 off Lervig in the Hardanger Fjord, also at Floro. Sars has found it as 

 far north as the Lofoten Islands.

Firth of Clyde, 1860 (Mr D. Eobertson) ; south of RockaU, 

 lat. 56° 7' N., long. 14° 19' W., 630 fathoms (' Porcupine,' 1869). 



On the Norwegian coast I have taken it in 150 to 180 fathoms, off 

 Midto Lighthouse, and in Stoksund 80 to 100 fathoms, both in the 

 Hardanger Fjord. 



Sars has also dredged it in the Hardanger Fjord off the Island of 

 Huso, 100 to 105 fathoms, and at Lofoten in 120 to 200 fathoms. 



There are six European species belonging to these two genera. The 

 genera are distinguished from all other Cumacea by having a well- 

 developed, long, flattened, linguiform telson, which is broad at the 

 extremity, and terminates in several spines ; the carapace is small, the 

 three first pair of feet have fully developed natatory palps, and the 

 two following pair two-jointed rudimentary palps. In the male the 

 -intennules have a bunch of cilia at the extremity of the peduncle, and 

 the pleon is furnished with three pairs of natatory feet. 



The following more salient features will enable the species to be 

 separated. It is probable that more of these forms await discovery in 

 our own seas. 



Lamprops fasciata, G. 0. Sars. Carapace with three well-developed 

 oblique folds on the sides. Telson with one or two pairs of lateral spines, 

 and terminating in five spines — Britain, Norway. 



Lamprops fuscata, G. 0. Sars. Carapace smooth, rostrum acutely 

 produced. Telson with one or two pairs of lateral spines, terminating in 

 five spines — Norway. 



Hemilamprops rosea (Norman). Carapace smooth, rostrum not pro- 

 duced, the front forming nearly a right angle. Eyes well developed. 

 Telson not much contracted towards the extremity, with one or two pairs 

 of lateral spines, and terminating on seven or eight spines. Animal 

 niore or less stained with a rich rose colour — Britain, Norway. 



Hemilam.props assimilis, G. 0. Sars. Carapace and rostrum nearly as 

 in the last ; eyes rudimentary. Telson suddenly contracted near the
