Fig. 602. smootli. Length, twenty-eight himdrcdths 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.ntvea. Tliis spccics diiTcrs from 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 

 ( Stimpson) .

 SIiclls of New Englaiul, 39; Check Lists, 5. 



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

Fig. 603. ^^ygj^^y.flye hundredths of an inch; breadth, six hundredths 



J^ of an inch. 



^\ The animal is Avhite, hyaline ; tentacles almost joining 



%S each other at their bases, wdiere, on the external sides, are 



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



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



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



above projecting a little l)eyoiid 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 tlie depth of eight 

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