Decapodous Cephalopod Mollusks from the Marshall Islands' 
Gilbert L. Voss^ 
The cephalopods recorded in this report were 
collected in the Marshall Islands partly during 
Operation Crossroads by the oceanographic 
section of Joint Task Force One under the 
direction of Commander Roger Revelle in 
1946 and the Bikini Scientific Resurvey under 
the direction of Captain Christian L. Engle- 
man in 1947, and partly by the Pacific Science 
Board. Although the collection is a small one 
numbering only seven species and 27 spec- 
imens, it comprises the only records from 
this group of islands since the report by 
Hoyle in 1904 on the collections made by the 
"Albatross” in 1899-1900. 
Of the 27 specimens represented, only a 
single specimen was collected in 1947, five 
were taken by R. W. Hiatt under the auspices 
of the Pacific Science Board at Arno Atoll, 
and those remaining were cpllected in the 
original survey made in 1946. The Operation 
Crossroads material was collected by the fol- 
lowing individuals: J. C. Mart, L. P. Schultz, 
Birch, Frank Cali, J. P. Morrison, Myers, and 
Smith. It is interesting to note that Hoyle 
listed only one species of squid taken by the 
"Albatross” in these waters, Euprymna steno- 
dactyla (Grant), of which ten specimens were 
collected in 1946. 
The present specimens were all collected 
at the surface at night by means of a dip net 
and submarine light.

U. S. National Museum, and especially Dr. 
Harald A. Rehder, Curator of Mollusks, for 
making the facilities of that institution avail- 
able during the course of the study.

NOTES: The five specimens from Arno Atoll 
have been placed, with some hesitation, in 
the above species. The minute posterior spine 
on the shell and the arrangement, size, and 
distribution of the suckers of the tentacular 
club appear to be identical with those de- 
scribed and figured by Adam (1939^^)- Other- 
wise their possible relationship to S. tuber- 
culata and S. papillata seem to offer the same 
problem as discussed by him.
