EUCOl'lA UNGridLATA. 187 



EUCOPIA Dana (1852). 



The genus comprises four species, three of which are represented in this col- 

 lection. In the account t)f the "Siboga" Schizopoda I have given an analytical 

 key to the species and have dealt with the synonymy. 



5. Eucopia unguiculata (Willemoes-Suhm).

(partim). 

 1905. Eucopia unguicukda H. J. Han.sen, Bull. Mus. Ocean. Monaco, no. 42, p. 3. 

 1910. Eucopia unguiculata H. J. Hansen, Siboga-Exp., 37, p. 20, pi. I, fig. 3a. 



In this list I do not include Sars's account of his Eucopia auslralis Dana 

 in the "Challenger" Rept., p. 55, pis. 9-10, because he, as pointed out in the 

 "Siboga" paper, has confused three species, viz. E. auslralis Dana with figs. 

 1-2 on his pi. 9, E. sculpiicauda Faxon, to which his figures 13-17 on pi. 10 

 belong, and E. 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
