STALK-EYED CRUSTACEA. 



LL, and described above) differ from typical specimens^ as described and 

 figured by Kr5yer, in having a larger and somewhat differently shaped ros- 

 trum; and in the form of the petasma. These specimens were separated 

 from iS. edwardsii as a distinct species, S. halia^ in my preliminary report on 

 the " Albatross " Crustacea.* But I am now inclined to regard them as 

 large and mature individuals of 8. edwardsii Kroycrf notes a "rare variety" 

 of 8. edwardsii distinguished by a larger rostrum. 



8. edwardsii appears to be a surface species of wide distribution in the 

 tropical Atlantic and Pacific Oceans.

One specimen from Station 3412^ surface, 



This is also a surface species found in the tropical parts of both the Atlan- 

 tic and Pacific Oceans. Cf. Kroyer {op, cit)^ Bate {" Challenger" Macrura)^

One specimen^ 250 miles S.E. of Acapulco, lat. 13° 33' 30" N., long. 

 97° 57' 30^' W- Tanner net towed at 175 fathomS; and hauled to surface 



open, 8 p. M. 



This species, originally described from specimens secured by the " Chal- 

 lengcr " in the warmer portions of the Atlantic, has been previously recorded 

 from the Pacific (12° S., 113' W.) by Ortmann.+
