circular, with generally a small tubercular 
tooth placed in the middle and deep within 
the mouth, but which is sometimes very ob- 
scure and often totally wanting ; peristome 
thin, not margined, but slightly reflected 
and forming an umbilicus ; and behind the outer 
lip is a thick white rounded rib. 
This species varies very much in size, and in the 
compactness of the spire, (fig. 44.) 
Captain Brown has added to the list Pupa unideu'- 
tata Pfeiffer {Brown ^ B, iS'. t. 41. f. 4.) and P. Mden- 
tata Pfeiffer {Brown, B. S. t. 41. f. 6.). According 
to Rossmasler (i. 83.), these species of Pfeiffer are 
only varieties of P. marginata. Brown’s figures are 
so bad that it is not possible to determine what 
species they are intended to represent. 
c. Peristome slightly rejlexed; throat many ’•plaited ; 
cavity of the young shell simple. (Abida Leach.^
