Vertigo rupicola, BINNEY, I. c. 

 Leucochila rupicola, TRYON, Am. Joum. Conch., III. 307 (1868). 



From Key West to Arkansas and New England ; Louisiana ; Texas. It may, 

 therefore, be said to inhabit all of the Eastern Province. 



Mr. Say noticed the resemblance between this species and P. corticaria ; 

 future observations will, I believe, prove them to be identical. That procera 

 and rupicola are synonymous is fully shown by the comparison of numerous spe- 

 cimens. The length of the spiral cylinder varies considerably. The charac- 

 ters of the aperture are constant ; but the teeth, except those on the transverse 

 margin and at the extremity of the axis, are frequently wanting ; its outline is 

 well rounded, and the peristome broadly expanded. There is often an abrupt 

 curve of the outer peristome between the tooth of that side and its junction 

 with the body-whorl. The upper boundary of the aperture is distinctly marked 

 by the body-whorl, which makes a horizontal truncature of the superior part of 

 the oval. The, teeth, except the two constant ones, are deeply seated in the 

 throat, and cannot always be seen without considerable attention. 



Jaw low, wide, slightly arcuate ; ends but little attenuated, blunt ; no median 

 projection to cutting edge. 



Lingual membrane as usual in the genus (see PL IV. Fig. S). The cusps on 

 the laterals, however, are very much stouter. There are 5 perfect laterals ; 

 teeth, 11111. 



Genitalia not observed. 



Pupa corticaria, SAY. 

 Vol. III. PI. LXXII. Fig. 9. 



Shell whitish, shining, cylindrical, obtuse at the apex; whorls rather more 

 than 5, convex ; suture well impressed ; aperture lateral, two thirds as wide as 

 the last whorl, suborbicular, with a single tooth (sometimes two) on the parie- 

 tal wall, near the centre, and a tooth-like enlargement near the umbilical ter- 

 mination of the peristome, which is white, reflected; umbilicus very minutely 

 perforated. Length, 2| mill. ; diameter, 1 mill.
