286 MELANIIDiE. 



96. Melania [Plotia], sp. ? 



4 Telagu Patengan [Java] ; coll. Baron F. von Richthofen. 



Long. 17i, diam. 7 mil. I am quite unable to identify this 

 species. It somewhat resembles Mel. jugt'costis, also Mel. unifas- 

 ciata. 



97. Melania aus trails. 



Melania Australis, Lea, F. Zool. S. 1850, Victoria Eiver ; Smith, Voy, 

 Erebus, pi. 4, Jig. 3. 



? var. [? distinct sp.]. - 

 1 Australia [?] ; ex c. Madras Museum [29|t, 11^]. 



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, &c., of the Madras Museum; I have 

 found both equally untrustworthy. 



Sub-Genus MAINWABINGIA, nov. 

 Tt/pe 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 2J whorls, 

 closely resembling Adam's pi. XXXV, fig. lOA-B., operculum 

 of Hydrobia ulvce. 



98. Melania [Mainwaringia] paludomoidea, n. sp. 

 Long. 9i, diam. 4^^ 5 apert. lorg. 3| mil. 



Imperforate, conically produced, spire turretedly acuminate, 

 apex very acute, suture distinct ; of a rather yellowish, bright
