A. E. Verrill — North American Cephalopods. 
ter of largest suckers of sessile arms, ’75 inch. The arms appear very 
stout, especially at hase, and not very unequal in size. In form they 
agree well with those already described from previous examples. 
The ventral arms have the inner face broader than on the other 
arms, and the two crests along the outer angles are well developed. 
The suckers, so far as preserved, have the same characters as in the 
former examples ; the more proximal of those on the ventral arms 
are closer together in a longitudinal direction, but the rows are 
farther apart than on the other arms. The mandibles are dark brown, 
the tooth on the anterior alar edge of the lower mandible is large 
and prominent. 
The color, which is partially preserved, especially on the arms and 
on the ventral surface of the body, agrees pretty nearly with that of 
Ommastrephes , consisting of small purplish brown chromatophores, 
more or less thickly scattered over the surface. The back had a 
bleached appearance, as if the creature had laid upon the shore or 
floated at the surface, with the back exposed, for some time after 
death. 
Owing to the mutilation of the tips of the ventral arms, hectocoty- 
lization could not have been detected, if it had originally existed. 
The sex, therefore, could not be determined without cutting open the 
mantle. By everting the edge of the mantle, as far as possible, I 
could see, owing to insufficient light, only the tips of the gills, which 
are situated rather far back, but the reproductive organs could not 
be seen.
