of British Mollusca. 471 



Distribution. A specimen was taken by the ' Porcupine,' 

 1869, St. 65, lat. 61° 10' N., long. 2° 21' W., 345 fath., temp. 

 30°'0 Fahr.* Finmark {Loven), whole coast of Norway 

 and East and West Finmark, 60-200 fath. (Q. 0. Sars). 

 The following is Sars's description of this species : — 

 " Corpus breve et obesum, supine papillis minutis sparsis 

 obsitum, pallio ovato capite vix duplo longiore, margine an- 

 tico in medio angulum obtusum formante, pinnis semicircu- 

 laribus longe sejunctis ; brachiis robustis, lateralibus inferiori- 

 bus longioribus dimidium corporis longitudinem superantibus, 

 acetabulis magnis, biseriatis, regularibus ; tentaculis corporis 

 longitudinem vix assequentibus, apice breviter dilatato, ace- 

 tabulis minutis, longe pedunculatis, multiserialibus obsito. 

 Color fusco-rufescens, chromotophoris numerosis minutis. 

 Long., brachiis exclusis, 35 mm. tegmenta raduhe : 40. 



6. Rossia sublevis, Verrill.

Rossia sublevis?, Hoyle, Report ' Challenger ' Cephalopoda (1880), 

 p. 117. 



Mr. E. A. Smith records Rossia sublevis (Ann. & Mag. 

 Nat. Hist. ser. 6, iv. (1889), p. 420) as having been taken in 

 1889 by the ' Flying Fox ' in 250 fath. off the south of 

 Ireland. 



Distribution. North-east American coast, in 42-372 fath. 

 (Verrill), and by the < Blake ' exped., lat. 32° 33' N., 233-260 

 fath. {Agassiz). 



Is this distinct from R. glaucopis? I cannot think so. 

 Verrill's description of R. sublevis accurately accords with the 

 characters of the former species. With respect to distinctions 

 he writes : — " This species very closely resembles the Rossia 

 glaucopis, Loven, of Northern Europe, as figured by G. O. 

 Sars. The latter is, however, more papillose and has smaller 

 eyes and head, if correctly figured." But with respect to the 

 papillosity Verril says, " Upper surface of the body and head 



* This station is exactly on the line of demarcation of the British area, 

 but from the temperature ought not, I think, to be regarded as British. It 

 is impossible to define a more exact boundary than that I have given 

 at this particular spot (see introductory notes). The next station, 06, at 

 depth 207 fath., has temp. 4o 0, 7 Fahr. Had I gone one half degree 

 further east (i. e. 4° 30' W.) for N.E. line of boundary, it would have 

 fallen within the 100-fathoui Shetland area in places.
