Jaw and Lingual Dentition of Pulmonata. 190 
Tornatellina is recognized as a genus by Pfeiffer (Mon. 
VI), but by von Martens (Die Heliceen) is considered as a 
subgenus of Cionella. It now remains to be seen whether 
this peculiar dentition is shared by other species. 
I am indebted to my friend, Mr. A. 
ne T. E. Lansing, for the drawing of the 
. ES teeth here given. It represents the 
| central, with the first and second side 
Coren) teeth. There are an ‘exceedingly 
Ca large number of teeth beyond this, 
A of the same type quite to the exterior 
a margin of the membrane. The teeth 
are arranged obliquely in waving 
rows, as is also the case in Achatinella.

Already in connection with my friend, Mr. T. Bland 
(Ann. Lyc. Nat. Hist. of N. Y., X, 331, pl. xv), I have 
described and figured the jaw and lingual dentition of sev- 
eral groups or subgenera of Achatinella. Recently, I have 
received from Mr. J. G. Anthony, some more specimens in 
alcohol. I am indebted to Mr. J. H. Redfield for their 
identification. 
I find A. marmorata, Gould, of which A. plumbea, Gul., already exam- 
ined, is asynonyme, of the subgenus Partulina,* to have the same denti- 
tion as we have shown to characterize that subgenus as well as Achatinella 
S. Ss. 
Of Leptachatina there was the following: ¢textilis, Fér. The dentition 
is as in the other species of the subgenus examined by me. There are 
26-1-26 teeth, with 8 laterals. On pl. xiv, fig. G, I figure the transition 
from lateral to marginal teeth, and two decided marginals. These last 
* I use the subgeneric names of Von Martens.
