of British Mollusca. 143 



It is worthy of notice that even the var. aitenuata of Sars 

 is subject to considerable difference of contour. My example 

 from Tromso, received from Herr Schneider, though smaller 

 than that figured by Sars, being just 1^ inch, has an additional 

 whorl, and is narrower in proportion to its length, thus 

 approaching more in proportion to S. lachesis, to which, 

 however, its comparatively flattened whorls and twisted canal 

 show no approach. Locard records this species as taken 

 off the coast of Marocco by the ' Travailleur.'

One of the original British specimens procured by 

 Humphreys from fish-stomachs at Cork, which was in 

 Walpole^s collection and passed thence to that of Dr. Mason, 

 was kindly given me by the latter. ' Porcupine / 1869, off 

 the mouth of the Shannon, Ireland, 90 fathoms (St. 6) ; 

 * Flying-Fox,' 1889, 110 fathoms, off the south coast of 

 Ireland, a very fine specimen 52 mm. in length [E. A. Smith). 



* This was disputed by Jeffreys, but Friele has compared types, for 

 observations on which see his paper.
