 pi. 5, figs. 42 to 53. 



"Shell very small, pale horn-color, translucent, tapering 

 above the penultimate whorl; whorls a little more than five, 

 convex, with a well-impressed suture; aperture sub-orbicular 

 (the penult, whorl cutting off about one-third of the circle), 

 about one-third of the length of the shell ; margin sharp, with 

 a narrow contraction in the submargin, beneath which is a 

 thickening within, on which are the labial teeth; teeth eight, 

 five primary and three secondary; of the former the largest 

 is on the penultimate whorl, the next largest on the left side 

 of the aperture ; at the base, beginning at the left hand, is a 

 primary, then a secondary, a primary, a secondary, a pri- 

 mary and another secondary, extending nearly to the upper 

 extremity of the right margin; the last three primaries are 

 not constant in size; umbilicus open. Length 0.08 inch; 

 breadth 0.05 inch. 



"This species is easily distinguished from the preceding 

 (P. contracta) by its teeth/' (C. B. Adams, in Thompson's 

 History of Vermont, 1842, p. 158.)
