PACIFIC SCIENCE, Vol. VIII, July, 1954 
The specimens show a considerable rugos- 
ity on the dorsal surface of the head, the 
dorsolateral, and parts of the ventral surface 
of the mantle. This may have been caused by 
shipment wrapped in cheesecloth but this is 
uncertain. There are several tubercles over the 
eyes, a small patch of six or seven below each 
eye at the base of the arms, and a double row 
of elongated papillae or ridges on the latero- 
ventral surface of the mantle near the fins. 
It is interesting to note that no Sepia have 
been recorded from the Hawaiian Islands, 
which appear to share an otherwise similar 
cephalopodan fauna, although they are nu- 
merous to the westward throughout the East 
Indies, the Philippines, and Japan. The pres- 
ent specimens appear to be the most eastern 
Pacific record to date.

NOTES: The present specimens have been 
placed in this species, but their eventual dis- 
position must await a much needed thorough 
revision of the genus. Hoyle’s (1904) descrip- 
tion of this species, based upon the "Alba- 
tross” material from Arno Island, is very de- 
tailed and supplements Grant’s (1835) rather 
limited description in many ways. As Berry 
(1912: 315) notes, the differences between E. 
stenodactyla, E. scolopes, and E. morsel are trivial 
and based almost entirely upon the hecto- 
cotylized arm of the males. Indeed, as he 
remarks, the description of one Euprymna 
might very well do for all the others except 
for this organ. 
A comparison of the present specimens 
with the type of E. scolopes Berry from the 
Hawaiian Islands showed a number of differ- 
ences in the hectocotylized arm, the present 
specimens having larger suckers in only two 
rows, but the character of the hectocotylized 
arm being more dorsally curled in E. scolopes 
does not seem tenable, as this is in direct 
relationship to the preservation of the animal. 
The name scolopes is misleading, as the present 
specimens also have distinctly palisaded pedi- 
cels on the hectocotylized arms. 
As remarked above, the modified suckers 
of the right dorsal arm in the male are very 
large, in only two regular rows, and are born 
upon the ends of heavy stalks or pedicels. 
The rings are smooth and are closed by fleshy 
protuberances or dactyls which give them the 
appearance described by Hoyle and Berry of 
having only a dorsal slit or mouth-like 
opening.
