A REVISION OF THE AUSTRALIAN TURRIDH—HEDLEY. 261 
an Oniscia. The colour markings and the spiral grooves on the anterior 
part of the shell of Chemnitz favour the reference of Cythara to Strombus 
rather than, as by Smith,°8 to Mangelia lyruw Reeve, or M. funiculata Reeve. 
Hyen if it be granted that Schumacher’s Cythara is really a Turrid, it is 
a species unknown to modern conchology, and the genus has no substantial 
basis. Tryon? has stated that Otocheilus is “Cytharu,” in which case it 
would take precedence of the name here employed, but Dall ® regards it 
as absolutely synonymous with Lyriu. The genus Conopleura Hinds 
(type C. striata Hinds, 1844), is probably a deepwater representative of 
Hucithara. 
The genus Hucithura seems to be a constant associate of reef corals. 
Typically it is a rather solid turrited-fusiform shell, sculptured by bold 
longitudinal ribs, over-run by dense spiral threads, and decussated by an 
even finer radial striation. The aperture is as long, or longer, than the 
spire, fortified externally by a stout varix which ascends the previous 
whorl, includes a semi-circular sinus, and extends a free edge over the 
mouth. Within the lip are a series of short entering ridges, and the 
colamella bears a corresponding series of deeply entering horizontal bars. 
Corrections here offered of the ‘‘Chevert”’ records are as follows :— 
Mangelia ponderosa of Brazier (not Reeve) is here regarded as H. guntheri 
Sowerby; his M. goodalli is H. cylindrica; his balteata is coronata; his 
maculata is alacris; and his pessulata is celebensis.
