214 STALK-EYED CRUSTACEA. 
LI., and described above) differ from typical specimens, as described and 
figured by Kréyer, 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 my preliminary report on 
the “ Albatross” Crustacea.* But I am now inclined to regard them as 
large and mature individuals of S. edwards. Kroyer f notes a “rare variety” 
of 8. edwardsii distinguished by a larger rostrum. 
S. edwardsii appears to be a surface species of wide distribution in the 
tropical Atlantic and Pacific Oceans.

One specimen from Station 5412, surface. 
This is also a surface species found in the tropical parts of both the Atlan- 
tic and Pacific Oceans. Cf. Kriyer (op. cit.), Bate (‘‘ Challenger’ Macrura), 
and Ortmann (Decapoden und Schizopoden der Plankton-Exped.).

One specimen, 250 miles 8.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.
