EULIMA. 207 



I consider this species to be the Rissoa sinuosa of 

 Scacchi, although Philippi makes that a synonym of 

 his E. nitida. Chiereghini named it Turbo curvatus, 

 and Leach Balds arcuata. Macgillivray mistook it for 

 E. polita. (*M-)

E. stenostoma, Jeffr. in Ann. & Mag. N. H. 3rd ser. ii. p. 128, pi. y. f. 7. 



BODY milk-white : mantle thin, stippled with brown : snout 

 crescent-shaped, bilobed, flexible, and transparent, projecting 

 .a little beyond the foot : tentacles rather long and slender, with 

 rounded tips ; they diverge at an angle of about 25 ; at the 

 base of each is a patch of flake-white : eyes entirely wanting 

 in all the specimens (at least a dozen) examined by me at 

 different times : foot broad, squarish, and slightly bilobed in 

 front, narrowing behind to a bluntly rounded point. 



SHELL spike- shaped, slender, thin, transparent, glossy and 

 of a brilliant lustre : sculpture, extremely slight and close-set 

 spiral lines, which are discernible only under the microscope 

 and in certain lights ; the surface when examined by the aid 

 of a strong lens or hand magnifier appears quite smooth and 

 polished : colour milk-white : spire elongated, ending abruptly 

 in a blunt and semiglobular point : whorls 9, drawn out and 

 gently swelling ; the last occupies nearly one-half of the spire : 

 suture oblique, defined by a rather broad hern or border of flake- 

 white, which is encircled underneath by a clear and narrow 

 line ; this hem or border arises from a thickening of the shelly 

 material to form the suture or commissure: mouth narrow, 

 extending from a sharp angle above to an expanded and rounded 

 base; the inner or columellar side represents a very obtuse 

 angle : outer Up flexuous, with a rather thin edge, receding at 

 the top and advancing outwards towards the base : inner lip 

 reflected and twisted over the lower part of the pillar : oper- 

 culum filmy, pale yellowish-horncolour, marked with slight 

 flexuous striae in the line of growth. L. 0*35. B. 0-085. 



HABITAT : Fine sandy mud, in 7590 f., 4550 miles 

 S.E. by E. of the Whalsey Skerries, Shetland (J. G. J.); 

 30 miles off the same coast, in 82 f. (M f Andrew) . 

 Upper Norway (Loven and M.' Andrew). 



* Having a narrow mouth.
