4 Dr. H. A. Pilsbry on 
volvis, Pils. (1900), is thought by Dr. v. Mollendorff to have 
affinities with Gastrodonta or Sesara. The internal teeth in 
K. japonica are short transverse barriers at intervals of one 
third of a whorl, precisely similar to those found in Huconulus 
fulvus (Drap.), var. dentatus (Sterki), with which K. muléz- 
volvis has many features in common. A similar barrier exists 
in Kaliella ruga, Godwin-Austen, and some other Indian 
species. In K. multivolvis the barriers are very inconstant, 
completely lacking in some examples, varying in others from 
one to three in number. The same inconstancy attends the 
development of internal teeth, barriers, or lamine in Gastro- 
donta, Sagda, &c., in which the same species may have them 
strongly developed or totally absent, as is well recognized by 
all American students who have investigated the matter. In 
my opinion, therefore, Gastrodontella has no valid claim to 
generic rank. It belongs to Kaliella. 
It is not my purpose to discuss the classification of Japanese 
Helicide at any length in this place; but a single group calls 
for remark. In my ‘ Guide to the Study of Helices’ I pro- 
osed, under the name Mandarina, a new section of the genus 
Fulota for the reception of Heliz mandarina, Gray, of the 
Bonin Islands (Ogasawara-sima). It is now my opinion that 
this group has nothing to do with Hulota, but probably 
belongs to the Camenine. The nepionic shell is relatively 
large and acutely carinate (as in Camena), is sculptured with 
fine radial wrinkles at first, with spiral strie on the outer 
whorl, and usually continuing upon the postnepionic whorls, 
The adult shell is extremely heavy for a land-snail, and has 
a blunt expanded lip. The group is probably of generic 
rank, and will for the present include three species—Heliz 
mandarina, Gray, H. Pallasiana, Pfr. (hitherto referred to 
Ozxytes), and Nanina Ruschenbergert, Pilsbry. The latter 
two are depressed and openly umbilicate, and will form a 
separate section of the genus Boninia. All of them are 
probably confined to the Bonin Islands, although they have 
been attributed to various localities. The Bonin Islands 
have incontestably a fauna of “continental ”’ type. 
The new species described from Japan, the Loochoo and 
Bonin Islands, in the twenty-two papers published since 
Jan. 1, 1900, are as follows. I have appended to each, where 
necessary, notes on the synonymy &c. The list is arranged 
chronologically, and the papers are referred to by their 
numbers in the bibliography following.
