seven localities for his E. australis, viz. four in the Atlantic, the 

 fifth in lat. 46 0 46' S., long. 45°4i' E., the sixth in lat. 5o° 1' S., 

 long. 123° 4' E., the seventh in the North Pacific; besides he 

 says that his largest spécimen, an adult female, measures 5o mm 

 in length. Judging from thèse statements, from the fact that the 

 very large female shown in figs. i and 2 on Pl. ix can scarcely 

 belong to E. unguiculata, and from his représentation of the 

 maie already criticized, I a m convinced that Sars has mixed 

 together at least three species of Eacopia.

Description. — My largest Antarctic spécimen, an adult 

 maie, measures 70. 5mm in length. The front margin of the 

 carapace is a little more convex than in E. ungaiculata. The 

 eye-stalks are rather long, subcylindrical ; the whitish eyes look 

 forwards and occupy scarcely of the outer margin of the 

 whole appendage. Terminal joint of the exopod of the uropods 

 a little longer than broad. (Terminal spines on telson unfortu- 

 nately lost). — Besides two immature spécimens, measuring 

 respectively 19. 5 and 26 mm , are at hand. Their eye-stalks are, 

 as might be expected, a little broader than in the adult spé- 

 cimen, but yet distinctly longer and more narrow than in spéci- 

 mens of the same length of E. unguiculata, while the eyes 

 look essentially forwards, with their outer margin occupying 

 less than -j- of the outer margin of the appendage. The ter- 

 minal spines of telson are rather short in the small — broken 

 of in the other — spécimen. — Some other features are pointed 

 out above on p. 5. 



Remarks. — Dana's Antarctic spécimen — which is not 

 extant (see below) — measured one inch. His description is 

 imperfect and his drawings poor, but yet he says : « Eyes with 

 cylindrical pedicels, rather small », and this statement agrées 

 well with one of his figures which shows the eyes as terminal 

 on slender and moderately long stalks. Judging from thèse 

 particulars I think that my Antarctic spécimens can safely be 

 referred to E, australis, Dana.
