Gnathophausia \oëa G. O. Sars, op. cit. p. 44, Pl. vi, 

 figs. 6-10. 



Locality. — Stat. 1834, 1 spécimen. 



Remarks. — This beautiful deep-sea form has a nearly World- 

 wide distribution, wanting probably only in the Arctic and 

 Antartic Seas.

Eucopia australis G. O. Sars, op. cit. 

 p. 55, Pis. ix-x. 



Localities. — Stat. i63q, 7 spécimens; 

 stat. 1676, 2 spécimens; stat. 1844, 4 spéci- 

 mens ; stat. 1849, 10 spécimens; stat. i85i, 

 2 spécimens ; stat. 1 856, 4 spécimens ; stat. 

 1874, 1 spécimen. 



Remarks. — This deep-sea form is com- 

 mon in the whole Atlantic ; its distribution 

 seems to be even somewhat wider than that of 

 Gnathophausia \oëa. — An outline of first tho- 

 racic leg is inserted for comparison with the 

 same appendageof the two following species. 



3. Eucopia intermedia, n. sp. 



(Figs. 2-3.) 



Description. — Only one immature spécimen is at hand, but 

 it is so characteristic that it can be looked upon with certainty 

 as a new form. As to gênerai aspect it resembles E . sculpticauda
