A. E. Terrill — JTorth American Cephalopods. 
421 
inches) ; of largest suckers, 10 mm (’38 of an inch). It was measured 
while living. 
The body, when living, was short and broad, and so soft and gel- 
atinous that, when out of water, it could not retain its natural form. 
When placed in a large pan, it flattened out and filled up the vessel, 
like a mass of rather stiff jelly. Color, in life, pale bluish white, 
speckled tvith rusty orange-brown chromatophores ; inner surfaces of 
arms dark purplish brown ; suckers white. 
Two detached and somewhat mutilated arms, with portions of a 
third arm and of the basal web, of a large specimen, formerly de- 
scribed by me as Octopus f sp., but which I now refer to this species, 
were taken by Mr. Agassiz, on the “Blake,” in 1880, at station 336, 
X. lat. 38° 21' 50", W. long. 73° 32', in 197 fathoms. 
The largest of these arms is 420 mra long and 36 mm broad. The 
suckers are large, prominent, subglobular, with a contracted aperture, 
and having a thin membrane around the outer margin. They form 
two alternating, rather distant rows, except near the base, where 
several that are somewhat smaller than those farther out, stand nearly 
in one row, with wide spaces between them. Diameter of largest 
suckers, 9 to ll mm ; distance between their centers, 20 to 35 mm . Color, 
dark purple. (PI. LI, fig. 3.) 
Smaller specimens were taken by us, this season, off Martha’s 
Vineyard, in 310 to 715 fathoms; stations 938, 952, 953.
