*• Sliell li^^lit amber colour, sometimes wliitc siunotli, glossy, stronijly 

 niched, haU-uioon shaped, basal margin [)iiiclied in about two lines lunjr. 

 running somewhat like a shouhler, then slightly venti'icose, from that lo 

 the apex rciriihirl}' tapering, apex with a minute perfoi'ation, entiie. 



Lengtli, 14 lines ; diani of base at shouhler, 1 : below, \ line.'' 



At the ciuiclusion of his description Hi~azier remarks that '"The lower 

 part of this species resembles the spines of 8ea Ui-chins ' Erhiniiln'' 

 The greater part of the specimens are encrusted over with a tine coatin;j 

 of coral-like substance." 



To the description the following localities are appemieil : I'rincess 

 t'harlotte Bay, North- Ivast .Australia, lo fms., sandy mud : t'ape (irenville, 

 North-l'iast Australia, "20 fnis., mud ; Voi-k Island. Torres Sli-aits, 1:> fms., 

 iiKid mud bot-t-om : Daiiiley Island. Toires Straits. 5. 15, 20, 30 fms., 

 mud, sand and sandy mud bottom. 



'I'liese specimens are housed in the Macleay Museum at the I iiiver>ity 

 of Svdiiev, and 1 am indebted to Mi-. John Sliewan For his c<jurtesy in 

 placing them at my dispt)sal for examination. 



.\s a l)"nliiHn III the s[»ecitic name of /"-r. had been preoccupied by 

 Schlotheim- and Turton,-' antl was again used by Hilgard and Hopkin>' in 

 1878. In the Manual of Conchology Pilsbiy iind Sharp refer this foim 

 to t''.idiilii.i t .' l<(en'-<^ Bi-azier, and make the following lemaik: — "Desciibed 

 as Dentaliniit, the specific name being preoccupied, it seems to be a 

 Cnliilns or a Uilriipn. We base not seen specimens, but the last clause 

 of Brazier's observations suggest the latter genus." 



An examination of the '• Chevert " material in tlie Macleay Museum. 

 and of the material in the Australian Museum (paratyjies) shows that 

 Ihi/I.iliinii I'lerr may be definitely removed fiom the Molliisca lo the 

 Annelida : and in considering the geographical distribution of these foinis, 

 mv conclusions point to the improbability of this being referable to the 

 European Ditrypa cornea, and it is tlierefoie regarded as a new species.
