 pair, 187; of left, 178; to edge of web, 110; breadth of body, in 

 middle, 46 ; breadth of head, across eyes, 38 ; breadth of dorsal 

 arms, at base, 8 ; diameter of largest suckers, 3 ; length of spoon- 

 shaped end of right arm of third pair (hectocotylized), 35 ; breadth, 

 16; length of rest of arm, to mouth, 65'"™. 



Taken from the stomach of a lialil)ut, 36 miles east from the N. E. 

 Light of Sable Island, in 160 to 300 fathoms, by Charles Rucklcy, of 

 the schooner " Fl. A. Duncan," and presented by him to the U. S. 

 Fish Commission, 1879. A smaller, mutilated specimen was also taken 

 from the stomach of a halibut, from Banquereau, off N. S., in 150 

 fathoms (lot 678), and presented to the U. S. Fish Commission, by 

 Captain Charles Markuson and crew, of the schooner " Notice," April, 

 1880. The latter specimen was, however, in too poor condition to 

 afford any additional characters, and may, perhaps, belong to O. 

 lentxs. 



This species diifers from Octopus Bairdii V., O. lentiis V. and 0. 

 piscatortini V., from the same region, in its longer and larger body, 

 and especially in haviug the basal suckers in a single row. The 

 ' spoon ' of the hectocotylized arm is very much larger than in 0. 

 Ord)il(indicus, and considerably larger and flatter and more deeply 

 trilobed at the end than in 0. Bairdii.

Body, mantle, and siphon as in Octopus. Suckers in a single vow 

 on all the arms. In the male the right arm of the third pair is hec- 

 tocotylized by the formation of a small spoon-shaped tip and a lat- 

 eral groove, nearly as in some species of Octopics. 



Eledone verrucosa Verrill.
