332 PYRAMIDELLID^. 



Fig. 602. smooth. Length, twenty-eight hundredths of an inch ; 



breadth, four hundredths of an inch. 



Animal white ; head short ; tentacles triangular, very 



broad, with the eyes at nearly the middle of their bases ; 



foot elongated with an arcuated indentation at its anterior 



terminus. 



T.nivea. rpj^j^ spccics dlffcrs froui T. interrupta in being more 

 slender, in wanting revolving lines, and also totally in its station, 

 the deeper parts of the Coralline Zone. It was taken in forty fath- 

 oms, on a muddy and gravelly bottom off Grand Manan, a large 

 island lying off Eastport, Maine, at the mouth of the Bay of Fundy 

 (^Stlmpsori). 



Genus EULll^IA, Risso. 1826. 



Shell elongated, white, smooth, polished; spire produced, many- 

 whorled, frequently with an interrupted varix on one side, apex 

 acute ; aperture oval, pointed behind ; inner lip reflected over the 

 pillar ; axis imperforate ; outer lip thickened internally. 



Eulima oleacea. 



Eulimn oJeacca, Kurtz find Stuipson, Proc. Bost. Soc. iv. 115 (1851). — Stimp.son, 

 Shells of New Englaml, 39; Check Lists, 5. 



Shell small, subulate, solid, very shining, white, marked with 

 light brown transverse l)ands ; whorls twelve, flattened, closely 



coiled ; suture inconspicuous; aperture small, ovate. Length, 

 Fig. 603. f;ygi^j-y_five huudrcdths of an inch; breadth, six hundredths 



of an inch. 



The animal is white, hyaline ; tentacles almost joining 



each other at their bases, wdicre, on the external sides, are 

 ^'cea'^' ^^^® eyes, which may be seen through the shell, when, as is 



usually the case, the head does not project beyond it. Foot 

 short, broad, slightly produced at the anterior angles ; the lobe 

 above projecting a little beyond it. 



This is a very variable species, especially as regards the form and 

 length of the aperture. Conrad has described two species from the 

 Miocene of Virginia which closely resemble this. It was dredged 

 in Buzzard's Bay, several miles from land, at the depth of eight 

 fathoms, where the bottom is composed of a soft gray mud. QStimp-
