of trunk-legs in the maie (Pl. x, figs, i3, 14 and 16) and from 

 some other of his figures, I a m convinced that his material 

 comprised at least three species. Ail subséquent authors fol- 

 lowed Sars in referring every spécimen from the Atlantic or the 

 Pacific agreeing moderately well with his account of female 

 spécimens in the Challenger Report to E. australis, Dana; in 

 the treatise published a few months ago I did the same, and 

 enumerated seven stations. 



But in a fine material of Schizopoda secured by the Swedish 

 Antarctic Expédition and received in this spring I found three 

 spécimens of an Eucopia resembling on the whole the common 

 Atlantic form, but one of the spécimens is so gigantic that it 

 created suspicion on the mat ter. Consequently I examined the 

 whole material at hand of E. australis sens. Sars, and will 

 now give the results. 



Ail spécimens from the Atlantic — of course excepting those 

 belonging to E. sculpticauda, Faxon, and E. intermedia, H. J. 

 H. — and the majority of spécimens collected by the Siboga in 

 the East-Indian archipelago agrée with each other; one of the 

 largest spécimens in the Monaco collection measures 2C) mm , an 

 adult female in the Ingolf material 37 mm and a maie 38 mm in 

 length from the front end of the head to the tip of telson. Ail 

 thèse spécimens belong unquestionably to the same species, for 

 which the following characters can be pointed out. The eye- 

 stalks are rather short and broad, seen obliquely from above and 

 from the side nearly oblong-ovate ; the whitish or yellowish 

 eyes (light red in living spécimens), look essentially outwards, 

 occupying more than -y, frequently about -j-, of the outer 

 margin of the whole appendage (eye-stalk + eye). The front 

 margin of the carapace is slightly convex. The terminal joint of 

 the exopod of the uropods is in the adults distinctly broader 

 than long, in not full-grown spécimens sometimes nearly as 

 long as broad, but not longer than broad; the terminal spines 

 on telson are very long. — AU the spécimens examined by 

 Willemoës-Suhm were taken in the Atlantic; that at least the 

 major part of them belonged to the species just characterized is 

 quite certain, but judging from the shape of the front margin 

 of the carapace (fig. 1 a) in a large maie measuring 3j mm , it may
