A. E. Terrill — North American Cephalopoda. 
345 
One specimen (?) from Charlotte Harbor, Fla., is much larger 
than usual. It has the mantle 130 mm long; diameter of body, SB™ 111 ; 
length of dorsal arms, 45 ram ; of 2d pair, 55 mm ; of 3d pair, 65 ram ; 
of tentacular arms, 145 mm . 
This species appears to have a wide distribution along the warmer 
parts of the American coast. The original specimen, described by 
Blainville, was from Brazil. D’Orbigny records it from Rio Janeiro. 
It extends northward to Delaware Bay. I have also seen specimens 
from Florida and from Mobile Bay, Alabama.

Although this species has not been recorded from north of Cape 
Hatteras, it is introduced here, because its common occurrence at 
the Bermudas and Florida renders it probable that it will, at times, 
be found farther north. 
It differs from the related species in having a pen without any 
marginal thickenings; the lateral tins commence at a short distance 
behind the mantle edge (5 m,u to 8 mm ) and, taken together, have a 
long-rhomboidal figure, broadest nearly in the middle, and obtuse 
posteriorly ; the sessile arms have wide marginal membranes ; the 
dorsal arms are compressed, and much shorter than the others ; the 
lower lateral arms are much the largest, with a strong dorsal keel ; 
the suckers on the sessile arms are so crowded as to appear almost 
as if in four rows. 
The tentacular club bears four regular rows of large suckers, the 
median ones but little larger than the lateral; small distal suckers in 
four regular rows, the lower ones largest. The larger suckers have 
regular, rather long and slender teeth, those on the inner edge
