Remarks. These specimens differ only in one small detail from the description of B. brucei. 

 Tattersall (1913, p. 869) stated that there were no spines arming the inner margin of the endopod of 

 the uropod. In the Discovery specimens there is one small very inconspicuous spine just distal to 

 the statocyst. 



Distribution. The types of this species were taken in the Weddell Sea by the Scottish National 

 Antarctic Expedition. The Discovery records indicate that it is a deep-water form confined to the 

 Antarctic and the colder waters of the South Atlantic. 



Boreomysis atlantica Nouvel, 1942 



1942c Boreomysis atlantica Nouvel, p. 3, figs. 5-8. 

 1943 Boreomysis atlantica, Nouvel, p. 55, figs. 66-76. 



Occurrence : 



St. 100C. 4. x. 26 (day). West of Cape Town, 2500-2000 m., 1 $, 17 mm. 



St. 245. 10. vi. 27 (day). West of Tristan da Cunha, 2000-1800 m., 1 imm. S, 22 mm. 



St. 395. 13. v. 30 (day). North-east of South Georgia, 1600-1500 m., 1 adult $, 21 mm. 



Remarks. Nouvel's type was a very badly mutilated adult female whose length he estimated as 

 approximately 23 mm. The only detail in which the Discovery specimens differ from the type is in 

 the cleft of the telson which is slightly deeper — rather more than one-fifth of the length of the telson 

 compared with one-sixth in Nouvel's female. 



Distribution. The Discovery records from the South Atlantic considerably extend its known geo- 

 graphical range, the type having been captured off the Azores.
