10 On the Schizopods collected hj the ' Oceana.'' 



with the terminal spines crescent-shaped and denticulate 

 along the upper face ; lateral margins armed for the usual 

 distance with large spines, separated from each other by 

 intervals occupied by a few smaller spines. Uropods shorter 

 than tclson ; the proximal joint of outer uropod terminating 

 externally in a spine about one fourth as long as distal 

 joint. Colour red. Length 39 mm. 



The only known specimen was taken in net 4 I, fished at 

 1770 fathoms and thence to the surface. 



Eucopia australis, Dana. 



A single specimen was taken in each of four hauls, in nets 

 working between 500-1710 fathoms and the surface. One 

 of the examples measured 33 mm. in length, which is not, 

 however, quite the full size of the species, since it is known 

 to reach at least 50 mm. 



Previous to the 'Oceana' cruise the only record of this 

 species from near our coasts is one by Caiman, who records 

 its capture by the R. I. A. expedition in 1888 off the west 

 coast of Ireland in 1020 fathoms. We have since recorded 

 it from soundinffs of less than 1000 fathoms.

'Note added in Pt'ess. — Hansen's Preliminary Report on 

 the Schizopoda of the ' Pi incess Alice ' appeared while this 

 paper was in the press. In correcting proofs we have 

 adopted his view of the synonymy of the species mentioned.
