470 Rev. Canon Norman's Revision 



area of our own seas I could at once pick out with certainty 

 specimens of many forms which I could rightly, by differences 

 of form, sculpture, and colouring, assign to their special 

 habitats. 



For description and good figures of the species I would 

 refer to the ( Challenger ' Report. 



The males are at once known from the females by the outer 

 rows of suckers of the arms, especially of the second and third 

 pair, being much more developed than those of the central 

 rows, while in the females the size of the suckers in all the 

 rows is subequal. The left dorsal arm of the male is also to 

 some extent hectocotylized. 



This was formerly regarded as a very rare species on our 

 coast ; but the use of the trawl has shown it to be far from 

 uncommon in 40-90 fathoms in the Clyde district and off the 

 west of Scotland. It was also taken in the ' Porcupine' 

 expedition in the Clinch and off the coast of Wexford, and 

 by the ' Triton ' off the Butt of Lewis in 40 fathoms (Hoyle). 

 Other localities are Dublin Bay (Ball), Isle of Wight (Forbes 

 and IJanley). 



Distribution. Kattegat (Steenstrup) , South Sweden (Loven), 

 South and West Norway (G. 0. Sars), Mediterranean (d'Or- 

 bigny)) Naples (Staz. Zool. !). 



Subgenus Fbanklixia *. 



Suckers of the arms in two rows only throughout their 

 length. Besides the species here described the following will 

 fall into this subgenus : — R. megaptera, Verrill, and appa- 

 rently Heteroteuthis tenero, Verrill.

Two specimens taken by Jeffreys in 60-100 fathoms off the 

 north of Shetland, and a specimen is in my collection which 

 I dredged on the Outer Haaf, Shetland, in 1867. 



Professor Steenstrup and Mr. Hoyle have both examined a 

 specimen labelled in Jeffreys's handwriting "Rossia papilli- 

 fera, Shetland/' which appears to have been the type of R. 

 I apillifera, and they have identified it with Loven's species.
