SUHIZOPODA, STOMATOPODA, AND NON-ANTARCTIC 1SOPODA. 183 



Current, but rather further south. It is only known from five other specimens, three 

 recorded by HANSEN from the North Atlantic, one by HANSEN from the East Pacific, 

 and the type, captured by the V<iltln-i<i in the South Atlantic. It is one of the 

 largest known Euphausians.

Euphausia Krohnii (Brandt). 

 Discovery. 



Off Madeira, tow-net Fifteen. 



This species seems at last to have found a name which may be considered more 

 or less a permanent one. It has been known during the last ten years successively as 

 Euphausia pellucida, bidentata, and Mullen; but HANSEN (1910) has definitely 

 established that Thysanopoda Krohnii, Brandt, an earlier name than any of the 

 above, was applied to specimens identical with those of the later species. By this 

 name, therefore, the species must henceforth be known.
