MOLLUSCA. 
nata inoperculata (also a note on them in Rep. Brit. Ass. for 1881, 
pp. 19G & 197) ; those collected by the German travellers, by the Re- 
corder, Nachr. mal. Ges. [Oct.] 1881, pp. 134-138. The character of the 
land shells is rather peculiar, distinctly nearer African than Indian types, 
but without doubt nearest to, and partially identical with, the few 
known land shells of Southern Arabia (genera Otojmma, Lithidion, 
Buliminus). Godwin- Austen states a nearer alliance to Madagascar, on 
account of the genus Tropidophora^ but the Recorder thinks that what 
he describes as Socotran species of this genus, belong rather to Lithidion. 
Only 2 fresh-water shells known, Melania hiberciilata, Indian and 
African ; and Planorbis exustiis, only Indian. 
Zanzibar. 5 new land shells by J. W. Taylok, J. of Conch, hi. 
pp. 142-144. 
Lalce region. New or little-known land shells from between the East 
Coast and the great lakes, generally resembling those known from the 
coast, and fresh-water shells from the lakes Tanganyika and Nyassa, 
mostly very peculiar [see Zooi. Rec. xvii. Aloll. p. 25], but including also 
Melania tuberculata, Lanistes purpureus andom^m, Limncea natalensin, and 
Vnio niloticus, described and most of them figured by E. A. Smith, 
P. Z. S. 1881, pp. 276-300, pis. xxxii.-xxxiv. ; additions subgen. Pararne- 
lania, id. 1. c. pp. 558-561. This author has also published a list of 16 
terrestrial and 31 fresh-water species from the lakes Tanganyika and 
Nyassa, with some general observations, in J. Thomson’s “ To the 
Central African Lakes and Back” (London: 1881, cr. 8vo), vol. ii. 
pp. 295-298. H. CiiOSSE gives a recapitulation of Smith’s papers of this 
and the preceding year in J. de Couch, xxix. pp. 105-139, & pp. 277-306, 
pi. iv. Only the figured species will be mentioned below, with the names 
of those which are changed. [Crosse is no doubt right in the conclusion 
that the resemblance of the fresh-water shells of this lake to marine 
genera is not so great as was presumed.] 
Mayotte Island^ Comores. 27 inoperculated, 12 opei*culated land shells, 
2 Auriculidce and 1 Assiminea^ including many new species and 1 new 
genus (Cyclosurus'), collected by M. Marie, described by A. More let, 
J. de Couch, xxix. pp. 212-241, pis. ix. & xvi. 
Nossi-Be and Nossi-Coinba, islands on the N.W. shore of Madagascar, 
17 species of inoperculated and 4 operculated land shells, 3 Limnoiidce, 
5 Auriculidce and 8 fresh- water operculated snails, enumerated by 
II. Crosse, J. de Conch, xxix. pp. 189-212. 
Mascarene and Seychelle Islands. G. Nevill points out that their 
land snails agree generally more with those of the Andamans, Nicobars, 
Sumatra, and the Moluccas, than with those of Cis-gangetic India, or 
with European fossils; J. A. S. B.l. pt. 2, pp. 125-127. 
Ascension Island. Helix similaris (Fer.), E. A. Smith, Ann. N. H. (5)
