arms are well shown, but these are about equally bi'oad in S. pterojms 

 and S. megaptera, and are also ])resent in all the related species of 

 this group. 



Owen's specimen had a total length of 3 feet; length of body, 15 

 inches; of head to base of dorsal arms, 3-7; of third pair of arms, 

 12; of tentacular arms, 21; breadth of caudal fin, 12*6; length of 

 their attached bases, 6-6; breadth of body, 5; length of 1st, 2d, 3d, 

 4th pairs of arms, 8-9, 11, 12, and 9'6 inches, respectively. The spe- 

 cimen is a female. It agrees very closely in size with the Bermuda 

 specimen described by me, and its proportions do not diifer more 

 than is usual wnth alcoholic specimens of any species, preserved 

 under different circumstances, and in alcohol of different strength. 

 The original specimen of S. megaptera is considerably larger. 



Ommastrephes illecebrosus Y. (See p. 268.) 



This species was taken in many localities, ttiis year, by the \J. S. 

 Fish Commission, in deep water, off Martha's Vineyard. ]\iiOst of the 

 living specimens were yoiing, but large ones were often taken from 

 the stomachs of bottom-dwelling fishes, in the same region, showing 

 conclusively that it regularly inhabits those depths.

Mr. H. L. Osborn, in the American Xaturalist, vol. xv, p. 366, 

 May, 1881, has given an account of the habits of this squid, at New- 

 foundland, and of the methods of capturing it there, for bait.
