TROSCHELIA BERNICIENSIS. 363 



Remarks. —The shell figured under this name was obtained by the Rev. S. N. 

 Harrison at Cranstal Point. My attention was drawn to it by Mr. A. Bell, who at 

 first regarded it as an nndeseribed species of Euthria, but now refers it, to the 

 E. gracilis of Locard. 1 The authors of the 'Moll. mar. de Rousillon ' identified 

 E. gracilis in their first volume with E. corned, var. minor;, Scacchi, but afterwards 

 adopted Locard's view that it is specifically distinct. It appears to differ from the 

 type form of that species in the well-marked nodulous costae of the upper whorls, 

 unfortunately missing from the Manxland specimen, and in its body-whorl which 

 is more tumid. 



It seems now to be generally considered that the E. minor of Bellardi 2 is a 

 different species.

Specific Characters. — Shell large, spindle-form, fairly solid ; whorls 7 or 8, 

 •convex, tumid in the centre, the last about two-thirds the total length ; orna- 

 mented by numerous spiral ridges, alternately large and small, extending to the 

 base of the shell, and by minute and closely-set curved longitudinal strise which 

 cross the ridges and produce slight decussation ; spire regularly diminishing 

 upwards, ending in a blunt, symmetrical point; suture deep; mouth oval; outer 

 lip expanded, semicircular, incurved above, making a right angle with the body 



1 I have not been able to identify it myself, but give it on Mr. Bell's authority.
