SYSTEMATIC DESCRIPTIONS 



In the statements of Station Distribution, showing the stations from which each 

 species was obtained by the Discovery Investigations, the stations have been grouped 

 according to the areas recognized in Table 3, p. 479. Particulars of the stations with 

 lists of the species obtained from each are given on p. 305. 



The geographical distribution of the species has been stated in general terms. The 

 term "Patagonian Shelf" covers the region east of the Patagonian coast down to 200 m., 

 and includes the Falkland Islands and the Burdwood Bank (see map, Fig. 60). Stations 

 below 200 m. in this region are recorded as "off Patagonian Shelf". The channels 

 around Tierra del Fuego, from the Straits of Magellan to Cape Horn, appear as the 

 "Magellanic Region". "Ross Sea" includes McMurdo Sound. 



Unless otherwise stated the figures have been drawn by means of a camera lucida 

 from specimens mounted in Canada balsam and seen by transmitted light. In many of 

 the figures drawn in this way the opesia has been arbitrarily stippled for clarity. 



Definitions of the families represented in this report are given by Harmer (1926).
