in 50-55 f. (M'Andrew) ; Arran I., co. Galway (Barlee) ; 

 Tenby (Lyons) ; Laugharne, Carmarthenshire (Lind- 

 say) ; Plymouth (Jordan) j Hayle (Miss Hockin) ; 15 

 miles from the Land's End in 50 f. (M f Andrew, fide 

 Forbes) . Norwich Crag ( Wigham, Thomas, and Wood- 

 ward); Red Crag (S. Wood). It has been dredged off 

 Christiansnnd in 60 f. by Danielssen, and in 40-50 f. by 

 Sars, in Christianiafiord by Asbjomsen, off Bohuslan 

 by Loven, and in 40-80 f. by Malm, and in the Kattegat, 

 with Crania anomala, by the last-named writer ; Tiberi 

 procured it in an immature state from coral-fishers at 

 Naples. 



The animal is extremely shy ; it takes alarm and shuts 

 itself up, even when you touch the table on which the 

 vessel containing it stands. Like its congeners it emits 

 a purple dye. The denticles of the tongue are slender 

 and curved. The shell may be distinguished from that 

 of S. Turtona by its smaller size, greater delicacy of 

 texture, finer and more numerous ribs (each of which 

 is generally furnished on the upper part with a short 

 spur) , and by its pretty fawn- or fleshcolour variegated 

 by white ribs. My* largest specimen is not much more 

 than 1^ inch long. Some are more elongated than 

 others; those from Ireland have a broader base and 

 faint traces of bands, disposed as in the preceding two 

 species, but of the same colour as the body of the shell, 

 although of a somewhat darker hue. Distortions occur 

 in which the spire is more or less bent ; and one has a 

 distinct but narrow umbilicus. 



This species was first described by Dr. Johnston, in 

 the Proceedings of the Berwickshire Naturalists' Club 

 for 1841. In Thorpe's (or Hanley's) ' British Marine 

 Conchology ' the specific name is spelt Treveliana. S.
