286 MELANIID^. 



96. Melania [Plotia], sp. ? 



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



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

 species. It somewhat resembles Mel. jugicostis, also Mel. unifas- 

 ciata. 



97. Melania australis. 



Melania Australis, Lea, P. Zool. S. 1850, Victoria River; Smith, Voy. 

 ErehuSjpl. 4, Jig. 3. 



? var. [? distinct sp.]. 

 1 Australia [?] ; ex c. Madras Museum [29L Hi]. 



A very doubtful form, with doubtfully correct habitat.

 opportunity of warning Euroi3ean conchologists against the 

 labels, identifications, &c., of the Madras Museum: I have 

 found both equally untrustworthy. 



Sub-Genus MAINWABINGIA, nov. 

 Ti/pe M. paludomoidea, n. sp. 



A new generic form, apparently connecting Melania and 

 PaUidomus, 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 2| whorls, 

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

 of Hydrobia ulvoe. 



98. Melania fMainwaringia] paludomoidea, n. sp. 

 Long. 9|, diam. 4yV ; apert. lopg. 3f mil. 



Imperforate, conically produced, spire turretedly acuminate,, 

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