SYSTEMATIC ACCOUNT 



Note. To economize space no synonyms are given for species which have been 

 described in the three previous reports. For purposes of reference the numbers given 

 in the eadier reports, on the Falklands, South Georgia and Antarctic, are printed in 

 brackets after the specific name, e.g. 2. Pyrgo murrhyua (Schwager) (F 3) (SG i) 

 (A 2). Those species recorded by Pearcey within the Antarctic convergence are noted, 

 together with the numbers of the stations at which they were obtained.
