286 MELANIIDA. 
96. Melania [Plotia], sp. ? 
4 Telagu Patengan [Java]; coll. Baron F. von Richthofen. 
Long. 173, diam. 7 mil. I am quite unable to identify this 
species. It somewhat resembles Mel. jugzcostis, also Mel. unifas- 
ciata, 
97. Melania australis. 
Melania Australis, Lea, P. Zool. S. 1850, Victoria River; Smith, Voy. 
Erebus, pl. 4, fig. 3. 
P var. [P distinct sp.]. 
1 Australia [?]; ex c. Madras Museum [293, 114]. 
A very doubtful form, with doubtfully correct habitat. 
Labelled “‘ Mel. australis, Reeve, Australia.” I may take this 
opportunity of -warning European conchologists against the 
labels, identifications, é&c., of the Madras Museum: I have 
found both equally untrustworthy. 
Sub-Genus MAINWARINGIA, nov. 
Type M. paludomoidea, n. sp. 
A new generic form, apparently connecting Melania and 
Paludomus, distinguished by the presence of rows of hairs or 
bristles, especially noticeable on the body whorl, which is 
ornamented with broad revolving brown bands ; not umbilicate ; 
apex remarkably acute, “quasi styliform”; peristome acute, 
columella thickened and excavately inflected. Operculum 
transparent, of one substance throughout,—that is, without any 
thickened process for attachment,—of very light horn-colour, 
without sculpture, ovate, acuminate at one end, at the other 
rounded, and distinctly terminally subspiral, with 24 whorls, 
closely resembling Adam’s pl. XXXV, fig. 10A-B., operculum 
of Hydrobia ulve. 
98. Melania [Mainwaringia} paludomoidea, n. sp. 
Long. 93, diam, 4; apert. long. 33 mil. 
Imperforate, conically produced, spire turretedly acuminate, 
apex very acute, suture distinct; of a rather yellowish, bright
