Hansen accepts only the following four specific names as thus far valid in this 

 genus : E. australis, Dana, 1852 ; E. unguiculatus, Suhm, 1875 ; E. sculpticauda, Faxon, 

 1895 ; and E. major, Hansen, 1910. The extraordinary length of the second, third, 

 and fourth perseopods, the delicate structure of the whole organism, and the great 

 depth from which it is commonly obtained, have combined to make descriptions 

 very imperfect through the provoking mutilation of specimens. 



Eucopia sp. 

 Plate XXXIIa. 



As the head, first perseopods, and telson are missing, nothing very definite can 

 be said about this species. The remaining limbs come very near to those which 

 Sars has figured from a young female which he assigns to E. australis, Dana (Rep. 

 Voy. " Challenger," " Schizopoda," pi. x. figs. 2, 5, 6, 7). As in our specimen the fifth 

 joint of the fourth perseopod is longer than the sixth, it cannot belong either to Suhm's 

 species or to Faxon's. For Hansen's E. major these limbs are not described, nor 

 are they distinctly figured by Dana. The spiny armature of the sixth and seventh 

 joints does not agree precisely with that shown by Sars. On the sixth joint there 

 are five large spines, the first much the longest, separated from the next by one 

 spinule, each of the others having two intermediate spinules, the last being followed 

 to the apex by eight slender spines. The finger is margined with seven spines, the 

 first very small, succeeded by three successively longer, the fourth followed by three 

 that are smaller and little projecting. The length might be roughly estimated at 

 30 mm., fourth perseopod 39 mm. 



Locality.— Lat. 39° 48' S., long. 2° 33' E. ; depth 2772 fathoms ; Station 468. 



Dr Tattersall's report on the Schizopoda of the Scotia has just appeared, 

 and I must apologise for having unwittingly interfered with them, but my plate had 

 been finished and the above notice written a long time ago. From the Station 

 468 above mentioned Dr Tattersall found the genus Eucopia represented 

 by " one fragmentary specimen, head end only," which he groups with damaged 

 specimens from various other deep-sea southern localities as probably belonging to 

 E. australis, Dana, as redefined by Hansen in 1905.
