454 Mr. E. S. Russell on the Cephalopoda 



togetliei- to form a deep conical " umbrella-cavity " ; tlie other 

 a greyish form, with the arms connected up by a loose v\'eb, 

 so that the " umbrella-cavity " is very flat and open. The 

 latter form seems to occur chiefly in the north of Scotland 

 and in the Shetlands. I hesitate to assign to it specific 

 rank, but it will be described and figured in the complete 

 account as a new variety. 



The majority of the specimens were females, but one or 

 two small males also occurred. One male of the aldrovandi 

 type showed a small hectocotylisation exactly resembling 

 that figured by Jatta for M. aldrovandi. I have had an 

 opportunity of examining also a male of this same type, 

 11 cm. in length, in the Museum of University College, 

 Dundee. It had been taken at Aberdeen in October 1893, 

 and showed quite clearly the hectocotylisation typical of 

 M. aldrovandi. One small male belonging to the other form 

 of M, cirrosa showed a slight hectocotylisation of the same 

 general character. In no case did I observe the paired cirri 

 on the tips of the arms of the male which are described by 

 Steenstrup and by Posselt as distinctive features of M. cirrosa. 

 There can be no doubt, I think, that Lamarck's Octopus 

 cirrhosus and liafinesque's Eledone aldrovandi are identical, 

 and that the Eledone cirrosa described by Steenstrup and by 

 Posselt is quite a different species, probably a northern form. 



It is unfortunate that the rule of priority demands the 

 naming of our common British species Moschites cirrosa, 

 when the identical Mediterranean form has been so beauti- 

 fully described and figured by Jatta under the name of 

 Moschites aldrovandi. 



Rossia glaucopis, Loven. 



This is distinctly a northern form, being recorded from 

 the Norwegian coast, Spitzbergen, Greenland, and in British 

 waters hitlierto only fiom the Shetlands and (as R. sublevis) 

 from 250 fath. to the south-west of Ireland {Hn^ith), It was 

 taken by the 'Goldseeker' chiefly in deep water in the 

 Faeroe Channel and near the Shetlands, but one small 

 specimen was taken in 200 m. as far south as Kinnaird 

 Deeps. Eggs of this species, imbedded in a mass of soft 

 sponge and containing the remarkably large embryos 

 (6-7 mm. long), were taken in 110 m. at 60° 26' N., 

 0° 14' W. 



Sepiola aurantiaca, Jatta. 

 This is undoubtedly a good species of Sepiola, About
