A. E. Verrill — North American Gephalopods. 



345 



One specimen ( $ ) Irom Charlotte Harbor, Fla., is much larger 

 than usual. It has the mantle 130'"'" long; diameter of body, 36"""; 

 length of dorsal arms, 45""" ; of 2d pair, 55"'"' ; of 3d pair, 65'"'" ; 

 of tentacular arms, 145""". 



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 fins commence at a short distance 

 behind the mantle edge (5'""" to 8"'"') 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
