[5] FAUNA OF OUTER BANKS, VINEYARD SOUND, ETC. 645 



Station 953 ; 715 fathoms ; one large and perfect male specimen. Sta- 

 tion 1031 ; 255 fathoms ; one young specimen. 



The former is the form recently figured by Steenstrup, under the 

 above name, and considered by him the adult of Gonatus amcenus. 



Onimastrephes illecebrosus Verrill. 

 Stations 918, 919, 923-925, 939, 940, 949, 1025, 1033 ; 45-258 fathoms. 



Desmoteuthis tenera Verrill. 



Station 952: 388 fathoms. Two specimens. 



Bosnia snblevis Verrill. 



Stations 924, 925, 939, 945-947, 951, 952, 997, 1025, 1026, 1028, 1029, 

 1032,1033; 106-388 fathoms. Some of the specimens recently obtained 

 agree more nearly with R. glaucopis Lov., as figured by G. O. Sars, than 

 any seen before. It may prove to be identical. 



Hcteroteiithis tenera Verrill. 



Stations 918, 919, 920, 921, 922, 940, 944, 949, 950, 1026, 1027 ; 45-182 

 fathoms. Eggs of this species were taken at stations 922, 940, 949, and 

 in several localities in 1880. They are nearly round, ivory-white or 

 pearly, attached to shells, etc., by one side, in groups, or scattered. On 

 the upper side there is a small conical eminence. 



Stoloteuthis leucoptera Verrill. 

 Stations 947, 952, 998, 989, 1026 (3 juv.); 182-388 fathoms. 



Octopus Bairdii Verrill. 



Stations 925, 939, 945-947, 951, 952, 994, 997, 998, 1025, 1026, 1028, 1033, 

 1035: 103-388 fathoms. 



AUoposus mollis Verrill. 



Stations 937, 938, 952, 953, 994 ; 310-715 fathoms. Two very large 

 females were taken ; one at station 937, in 506 fathoms ; the other at 

 994, in 368 fathoms. The former weighed over 20 pounds. Length from 

 end of body to tip of 1st pair of arms, 31 inches, of 2d pair, 32; of 3d 

 pair, 28; of 4th pair, 28; length of mantle beneath, 7: beak to end of 

 4th pair of arms, 22 ; breadth of body, 8.5 ; breadth of head, 11 ; diam- 

 eter of eye, 2.5 ; of largest suckers, .38. 



The only additional Pteropod taken this year is Triptera columnella 

 (Bang), from Station 947. Among the Gastropods there are a consider- 

 able number of species not obtained last year. Perhaps the most re- 

 markable discovery in this group is a flue typical species of Bolium 

 (D. Bairdii) taken alive in 202 fathoms. This genus is almost exclu- 

 sively tropical in its distribution. On our coast, D. galea extends north- 

 ward to North Carolina. This southern genus, with a large Marginella, 

 M. borealis v., taken both this year (Station 949) and last, Solarium 

 boreale v., Avicula Urundo, and various other genera, more commonly
