188 THE SCHIZOPODA. 



North Coronado Island, California. Its distribution southward in the three 

 large Oceans is still unknown. The majority of the localities enumerated 

 in the literature by the authors until July 1905 for E. australis Dana certainly 

 belong to E. unguiculata, but some among them to E. 7najor or E. australis, 

 and all specimens referred before July 1895 to E. australis should be reexamined. 

 The real E. australis Dana is a very large i^ntarctic species. The species has, 

 as far as I know, never been taken near the surface.

Remarks. — This species was estabhshed on a badly preserved female with 

 marsupium secured by the "Siboga" and measuring 42 mm. in length. The 

 specimens from the Pacific are also badly preserved; a male, from Sta. 4651, 

 is 58 mm. long, and a female, from Sta. 4742, with the marsupial plates perhaps 

 not fully developed is even, about 60.5 mm. But I am inclined to think that 

 these specimens had been a little shorter in the living state than in their present 

 bad and seeiningly extended condition. 



The species is easily separated from E. unguiculata by its much larger size, 

 the largest specimen recorded of the last-named species was only 38 mm., and 

 especially by having its short eyes looking forwards, occupying less than one 

 fourth of the outer margin of the whole appendage (stalk + cornea), while in 

 E. unguiculata the cornea looks in the main outwards and occupies more than 

 one third, frequently about two fifths, of the same outer margin. E. major 

 is readily distinguished from E. australis Dana by having the terminal joint 

 of the exopod of the uropods distinctly broader than long, while in E. australis 

 it is longer than broad ; besides the eye-stalks are projjortionately longer and 

 narrower in E. australis than in E. major. 



Distribution. — A single specimen was captured in the Indian Archipelago 

 by the "Siboga," and in 1910 some specimens were secured by the Prince 

 of Monaco in the Atlantic West of Southern Spain. In 1906 Ortmann enumer- 

 ated six localities in the North Pacific northwards to Lat. 56° 12' N. and one 

 locality in the West Indies for E. australis, but as E. australis Dana is an Ant- 

 arctic species his determinations cannot he correct. As he had separated E. 

 unguiculata from his E. australis I think that the specimens from his seven
