Taken from the stomach of a halibut, 36 miles east from the N. E. 

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

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

 Fish Commission, 1 879. 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 Markusou 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 0. 

 lentvs. 



This species differs from Octopus Bairdli V., 0. lentus V. and 0. 

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

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

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

 Gronli indict 18, and considerably larger and flatter and more deeply 

 trilobed at the end than in 0. Bairdii.

Body, mantle, and sii)hon as in Octopus. Suckers in a single row 

 on all the arms. In the male the right arm of the third |)air is hec- 

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

 eral gi'oove, nearly as in some sp?cies of Octopus.
