EUPHAUSIID^E. SIRIELLID^E. 23 



Dr. Gough sent us a specimen for examination which had 

 been taken in August 1903, in the tow-net, at Stat. 5 of 

 the International Fisheries Commission, that is to the south 

 of the Scilly Isles. 



It had previously been added to the British fauna by the 

 cruise of the ' Oceana,' when it was captured by Mr. G. 

 Murray at Stat. 2 of that cruise, lat. 52 45' K, long. 12 27' 

 W. (cf. Holt & Beaumont, 1. c. p. 30). 



RHODA INERMIS (Kroyer). 



1892. Boreophausia inermis, Norman, 1. c. p. 461. 



The genus Rhoda, Sim, was instituted in 1872, and we 

 quite agree with those who have used this name instead of 

 Boreophausia, Sars, 1883. The type species is Rlioda 

 Raxchii, M. $3iTS = Rhoda Jardineana, Sim. 



This has been taken twice by Dr. Gough in his tow- 

 nettings, in Feb. 1904 at Stat. 5, which is south of the Scilly 

 Isles, and in Nov. 1903 at Stat. 4. This last station is further 

 south, nearer the French coast and beyond the British 

 area. 



Tribe II. MYSIDAOEA. 

 Fain. 1. SIRIELLID^E*. 



[SlRIELLA NORVEGICA, G. 0. Sars. 



Taken in the tow-net by Dr. Gough in November 1903, at 

 Stations 3 and 4; the former is oft' Ouessant, the latter at the 

 entrance of the English Channel ; both stations are south 

 of the British area, but so near to it that there is every 

 probability of the species being taken off the Cornish coast.] 



SIRIELLA CLAUSI, G. 0. Sars. 



Near Drake Island, and in Whitsand Bay, Plymouth, 1889 

 and 1903 ; Scilly Isles (A. M. N.). 



SIRIELLA JALTENSIS, Czerniavsky = S. crassipes, G. 0. 



Sars. 



Starcross, 1883 ; Plymouth, 1889 and 1903 (A. M. N.). 

 Abundant among weeds on shores of Drake Island, Plymouth 

 (Garstang, iii. p. 221). 



* I am of opinion that the Subfamilies as used in my papers of 1892 

 should be raised to the rank of Families. A. M. N.
