1863.] ON NEW AUSTRALIAN MARINE SHELLS. 421 



Hab. Middle Harbour, Port Jackson (Coll. Angas.). 

 A species very similar in its general character to C. purpurea, Bl., 

 from the Mediterranean. 



II. Gasteropoda proboscidifera. 



The genus Adamsia, Dunker, appears to be an Australian form, 

 resembling a sculptured Cominella without the sutural constriction 

 of the whorls. To the type {Adamsia typica. Dunk.) we have 

 added a second species from Port Adelaide. We have further aug- 

 mented the genus Olivella by the addition of three very pretty spe- 

 cies from the coast of New South Wales. Our Amauropsis moerchi 

 is a southern representative of an arctic group of Naticidcs.

P. testa ovata, viridescenti-alba ; spira elata, conica ; anfractibus 

 5, postice angulatis, liris elevatis transversis et longitudinali- 

 bus late cancellatis, liris squamulis lamellosis longitudinalibus 

 imbricatis instructis ; anfractu ultimo antice coarctato ; aper- 

 tura trigonali-ovata, intus cinerea ; labia subplano, fuscovio- 

 lascente tincto ; lahro intus fusco-violaceo, liris pallidis trans-

Hab. York's Peninsula, South Australia {Coll. Angas.). 



A cancellated Trophon-\\\ie species, with the interior of the aper- 

 ture stained with rich violet-brown, and with the edge of the outer 

 lip white. 



2. Adamsia Adelaide, Ad. & Ang. (PI. XXXVII. fig. 2.) 



A. testa ovato-fusiformi, curneo-fusca ; spira elata, quam apertura 

 longiore ; anfractibus 7, convexis, lamellis longitudinalibus 

 confertis imbricatis et liris validis transversis nodulosis (in 

 anfractu ultimo 6) instructis; apertura ovata, antice sub- 

 rostrata ; labia simplici ; labro arcuato, margine subincrassato 

 vix reflexo. 

 Long. 8 lines, lat. 3| lines. 

 Hab. Port Adelaide {Coll. Angas.). 



This is a second species of a peculiar Australian form separated 

 by Dr. Dunker under the above name. It differs from A. typica, 

 Dkr., in its more elevated spire, and in the whorls being longitudi- 

 nally lamellose and not granular. 



3. Fusus tasmaniensis. Ad. & Ang. (PI. XXXVII. fig. 1.) 



F. testa ventricoso-fusiformi ; spira aperturam cequante ; luteo- 

 aurantiaca, plus minusve ruf a fascial a (fasciis tribus in an- 

 fractu ultima) ; anfractibus 7, in medio nodoso-plicatis, trans- 

 versim liratis, liris majoribus cum minoribus alternantibus ; 

 apertura trigonali-ovata, intus luteo-alba ; labia simplici, ar- 

 cuato, rostra brevi ad sinistram inclinata ; labro intus sulcata,
