178 DR WALTER M. TATTERSALL ON 



Finally, I desire to express my thanks to Dr BRUCE for entrusting me with this 

 collection, for much help with the literature, and for many courtesies in other ways ; and 

 to Dr W. T. CALMAN for allowing me to examine the collection of extra-Antarctic 

 Schizopoda made by the Discovery, and for permission to include the records here. 



Order MYSIDACEA, Boas. 



Family LOPHOGASTRID^E, G. 0. Sars. 



Genus Gnathophausia, W. Suhm. 



Gnathophausia gigcis, W. Suhm. 

 Scotia. 



Station 450, lat. 48 00' S., long. 9 50' W., South Atlantic, 1332 fathoms, 

 trawl. One female, 160mm. 



This specimen, which is in a rather poor state of preservation, is the largest 

 recorded one belonging to the species, the previous largest, the Challenger specimen, 

 measuring 142 mm. It differs from SARS' description and figures mainly in the less 

 pronounced teeth on the antennal scale and in the less produced infero-posterior 

 corners of the carapace. Both of these slight differences are due to age, and the 

 specimen otherwise agrees with G. gigas so closely that I have no hesitation in 

 ascribing it to this species. 



Family EUCOPIID^;, G. 0. Sars. 

 Genus Eucopia, Dana. 



Eucopia australis, Dana. 

 Scotia. 



Station 398, lat. 68 25' S., long. 27 10' W., Antarctic Ocean, vertical 

 tow-net, 0-1000 fathoms. One female, 50 mm. 



Station 414, lat. 71 50' S., long. 23 30' W., Weddell Sea, 2102 fathoms, 

 vertical tow-net, 0-1000 fathoms. One female, 35 mm. ; one frag- 

 mentary specimen, tail end only. 



Station 450, lat. 48 00' S., long. 9 50' W., South Atlantic, 1332 fathoms, 

 trawl. One female, 45 mm. 



Station 468, lat. 39 48' S., long. 2 33' E., South Atlantic, 2645 fathoms, 

 trawl. One fragmentary specimen, head end only. 



These specimens are in poor condition, but appear to belong, with very little doubt, 

 to E. australis as redefined by HANSEN (1905c).
