PUPA. 151 



A. Spire produced ; mouth horseshoe-shaped, with 

 teeth and folds ; outer lip somewhat thickened, and 

 more or less reflected. 



I. Pupa seca'le,* Draparnaud. Pl. IX. 



Body oblong, grey with a reddish or brownish tint above, 

 slaty-grey beneath, tubercles small, irregular and slightly 

 angular ; mantle covered with minute black specks ; tentacles 

 short, thick, somewhat diverging, bulbs oblong; foot usually 

 fringed, widening behind, but somewhat pointed at its ex- 

 tremity ; lingual ribbon with 100 rows of 41 teeth = 4100. 



Shell conical, elongated, thickish, nearly opaque, rather 

 glossy, light brown or brown, with numerous distinct oblique 

 striae in the line of growth ; periphery rounded, but somewhat 

 compressed ; epidermis moderately thin ; whorls 8-9, gradually 

 increasing ; spire produced, apex obtuse ; suture deepish ; 

 moiith horseshoe-shaped, considerably contracted by the laminar 

 folds, of which there are usually from eight to nine, two (or 

 sometimes three) on the base of the penultimate whorl (the 

 outer one is situated close to the upper margin of the outer lip, 

 and its outer edge is frequently furnished with a small denticle), 

 two on the pillar, and four on the inside of the outer lip which 

 are produced to some distance within the interior of the aperture, 

 and are distinctly visible on the outside, where they appear like 

 white lines ; outer lip thickened, slightly reflected ; umbilicus 

 minute, oblique. 



Inhabits many places in England, chiefly, though 

 not exclusively, in limestone districts, on rocks, in old 

 chalk-pits, and in woods at the roots of trees and 

 under stones, but it is a local species. It does not 

 appear to have been observed in Scotland, but it has 

 been found in South Wales. The Rev. J. McMurtrie 

 informs me that it occurs abundantly, of a large size 



A grain of corn (rye ?).
