214 STALK-EYED CRUSTACEA. 



LI., and described above) differ from typical specimens, as described and 

 fi"-ured by Kroyer, in having a larger and somewhat differently shaped ros- 

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

 from S. edwardsii as a distinct species, S. halia, in ray preliminary report on 

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

 larce and mature individuals of S. cdivardsii. Kroyer f notes a "rare variety" 

 of S. edtiwdsii distinguished by a larger rostrum. 



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

 tropical Atlantic and Pacific Oceans.

Tliis 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), 

 and Ortmann (Decapoden und Schizopoden der Plankton-Exped.),

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- 

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

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