GEOGRAPHICAL DISTRIBUTION. 
Moll. 13 
Limncea or Planorhis has been found, nor any representative of marine 
fauna. Mem. Ac. Petersb. (7) xx. No. 8, 73 pp. and 8 pis. 
Japan. Terrestrial shells, new or little known, described or discussed 
by Kobelt, JB. mal. Ges. iii. pp. 30-37, pi. i., by E. v. Martens, 
tom. cit. pp. 357-363 (Review of the Clausilice ; Pseudohyalina minus- 
cula, a North American species, lives also in Japan, 1. c. p. 359) and by 
E. Smith, Q. J. Conch. 1876, No. 8, pp. 118-121. 
China. 53 freshwater-shells from the Yangtsekiang described and 
figured by Heude in his Conchyliologie fluviatile de la province de

4. Africa. 
Madeira. Out of 179 species of land- and freshwater-J/bZ/wscci found 
in this island, 146, or nearly four- fifths, live nowhere else ; the probability 
that the rest have been introduced is discussed and asserted positively for 
6, probably in recent time for 6 others, rather probably in past ages 
for 7 more, and doubtfully, perhaps without human agency, for 4 more.
