146 HELICEA. 



Pupa carinata Gould was subsequently referred by him 

 to P. procera (1. c. iv. 3, p. 359) ; Pfeiffer retains it, not 

 having, however, seen the shell. Binney (Boston Proc. i. 

 105) considers it a doubtful species. No mention of it is 

 made in the Terrestrial Mollusks. 



Say never described any species of Pupa under the 

 names of gibbosa or minuta which are ascribed to him. 

 Pfeiffer considers the two identical. Roemer quotes mi- 

 nuta from Texas. On pi. 78, fig. 17, will be found a fac- 

 simile of the figure of gibbosa from Chemnitz. Pfeiffer's 

 description of minuta is as follows. From the two I should 

 consider the species identical with rupicola. 



PUPA MINUTA. T. vix rimata, cylindrica, nitida, pellucida, cornea ; 

 spira apice obtusa ; anfr. 6 convexiusculi, ultimus basi subcompressus ; aper- 

 tura subsemicircularis, 4-dentata; dentibus subaequalibus, 1 parietal!, 

 1 columellari, 2 palatalibus ; perist. expansuoi, sublabiatum, margini- 

 bus disjunctis, dextro superne arcuato. Long. 2|, diain. 1 mill. Ap. 

 oblique | mill, longa. Habitat in Pennsylvania. 



Obs. An forte varietas P. procerce ? 



I suppose Vertigo minuta of Adams's Genera to be this 

 species. 



It is also placed in the subgenus Vertigo by Binney, 

 though the animal had not been seen.

Pfeiffer (Mon. ii.) says that the corticaria of the Sym- 

 bolse is P. contracta.
