412 REPORT OF COMMISSIONER OF FISH- AND FISHERIES. [202 J 



large cluster of sperinatophores attached to the inner surface of the 

 mantle, behind the base of the gill, ana a smaller one, in front of the gill. 



In the second article referred to above, Professor Steenstrup discusses 

 the genus Sthenoteiithis versus "Ommatostrephes." He recognizes the 

 identity of Sthenoteuthis and his restricted genus OmmatoHtrvphes, as well 

 as the priority of date of the former. He also refers to 8. megaptera as 

 "Ommalostrephes megaptera. ," 



In the last paper* quoted above, Professor Owen has described a 

 cephalopod, without locality, under the name of Ommastrephes ensifer, 

 for which he proposes the subgeneric name, Xiphoteuthis. The latter 

 name is, however, preoccupied. His species is a typical example of my 

 genus SthenoteutMs (1880), and appears to be identical in every respect 

 with 8. pteropus (see my Plate VII, figs. 2, 2a, and Plate XVII), as 

 described by me. But Professor Owen fails to mention one of the most 

 characteristic features of this group of squids, viz, the connective 

 tubercles and smooth suckers on the proximal part of the tentacular 

 club. Nor is his figure sufficiently detailed to indicate this character, 

 nor even the actual arrangement and structure of the other suckers of 

 the club. The high median crest and broad marginal web of the third 

 pair of arms are well shown, but these are about equally broad in S. 

 pteropus and 8. megaptera, and are also present 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 base, 6.6; breadth of body, 5; length of first, second, third, 

 and fourth pairs of arms, 8.9, 11, 12, and 9.6 inches, respectively. The 

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

 specimen described by me, and its proportions do not differ more than is 

 usual with alcoholic specimens of any species preserved under different 

 circumstances, and in alcohol of different strength. The original speci- 

 men of 8. megaptera is considerably larger.

This species was taken in many localities this year by the U. S. Fish 

 Commission, in deep water, off Martha's Vineyard. Most of the living 

 specimens were young, but . large ones were often taken from the 

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

 clusively that it regularly inhabits those depths. 



* Among the other species figured and described in this paper, there is a handsome 

 species from the China Sea, described as Loligopsis ocellata, sp. now (pp. 139-143, pi. 

 26, figs. 3-8; pi. 27, figs. 1, 2). This is evidently not a true Loligopsis, and belongs, in 

 all probability, to my genus CaUiteuthis. It agrees very closely, even to the colora- 

 tion and the form of the fins and pen, with my C. reversa, but differs in having serrated 

 suckers. It is much larger than my specimen, but, like the latter, had lost the ten- 

 tacular arms. This species should, therefore, be called CaUiteuthis ocellata. The genus 

 probably belongs to the Chiroteuthidae.
