EUCOPIA UNGUICULATA. 187 
EUCOPIA Dana (1852). 
The genus comprises four species, three of which are represented in this col- 
lection. In the account of the “‘Siboga”’ Schizopoda I have given an analytical 
key to the species and have dealt with the synonymy.

(partim).

1910. Eucopia unguiculata H. J. HANSEN, Siboga-Exp., 37, p. 20, pl. I, fig. 3a. 
In this list I do not include Sars’s account of his Eucopia australis Dana 
in the “Challenger’’ Rept., p. 55, pls. 9-10, because he, as pointed out in the 
“Siboga”’ paper, has confused three species, viz. E. australis Dana with figs. 
12 on his pl. 9, EZ. sculpticauda Faxon, to which his figures 13-17 on pl. 10 
belong, and F£. unguiculata Will.-Suhm, to which at least the majority of his 
other figures belong.

Remarks.— The largest specimen, an adult male from Sta. 4676, measures 
33 mm. in length, and is thus uncommonly large; the largest female with marsu- 
pium, from Sta. 4655, is 32 mm. long. 
Distribution — The species is common in the Western Mediterranean and 
the northern temperate Atlantic and extends far northwards, as it has been taken 
in the Davis Straits at Lat. 61° 50’ N. and West of Iceland at Lat. 64° 38’ N., 
long. 32° 37’ W. (Ingolf-Exp.). It is known from some localities in the Indian 
Archipelago; as shown above, it is not uncommon in a good portion South of 
Lat. 4° S. of the area explored in 1904-1905, and it is probably widely distributed 
in the tropical and temperate Pacific; Ortmann (1906) records a specimen from
