170 Descriptions of New Species and Varieties of Shells, 



sides of which the outline is convex : clingy or brownish white ; 

 with an ill defined infrasutural line of dark brown, commencing 

 a little below the apex, and a spiral stripe of the same color 

 below the middle of the whorls, commencing at the middle of 

 the spire, and another stripe on the last whorl below the pe- 

 ri hery ; with the lip white : indistinctly granulated ; with fine 

 irregular strite of growth : spire convex, moderately elevated : 

 whorls nearly five, concave in the lower part, in the rest con- 

 vex, with the suture lightly impressed : aperture transversely 

 ovate or elliptical, with the lip well reflected backwards, and 

 much thickened, with three teeth on the lower side, of which 

 the outer pair are joined together at base, and all of which 

 have corresponding external furrows : umbilicus deep, partly 

 covered by the expanded and thickened columella. Inhabits 

 Westmoreland, 



G-reatest breadth 1.13 inch ; least breadth .98 inch ; height 

 .6 inch ; diameter of umbilicus .2 inch. 



Helix ing-ens, var. imperforata, without an apparent um- 

 bilicus, is more common than the umbilicated type. Another 

 variety, inuigxa, is of much less size, and is much less acute 

 at the periphery. It is also imperforate. 



Helix consanguinea. Shell depressed, rather more convex 

 above than below : very dark reddish brown, with a pale 

 brown or dingy white lip ; often with a pale stripe on the pe- 

 riphery : finely but strongly granulated on both sides : spire 

 regularly convex : whorls rather more than four and one-half, 

 moderately convex, a little depressed at the lower side next 

 the suture ; last whorl with a narrow not very prominent 

 keel on the periphery : aperture transversely ovate, much di- 

 lated, and produced laterally ; labrum well reflected back- 

 wards, and thickened, with four teeth below, of which three 

 have corresponding deep external furrows, labium closely ap- 

 pressed but thick : umbilicus rather narrow, deep, partly co- 

 vered with the dilated columella. Inhabits Portland.
