1880. Urosalpinx paivpe, Tryon. Man. Conch., vol. ii., 



p. 155, pi. 39, f. 495. 

 1895. Trophon paivte, Verco. T.R.S., S.A., p. 98, pi. 3, 

 f. 2. 

 Hab. — Port Phillip, Western Port, and coast generally. 

 Obs. — Dr. Vei'co says T. assisi, T. Woods, is a distinct species 

 from T. paivse, Crosse. We however have not seen sufficiently 

 good and constant characters in our examples of T. assisi to 

 regard it as a good species. We have seen shells from South 

 Australia and Tasmania which seem to conform well to T. Woods' 

 description of T. australis ; it is closely related to T. paivse, but 

 presents some differential characters which incline us to the 

 opinion that it may possibly be conveniently regai-ded as a 

 species, but if a large series be studied it may perhaps be found 

 necessary to include it as but another variation of T. paivee. 



Trophon eburnea, Petterd. 



1884. Trophon eburnea, Petterd. Jour, of Conch., p. 

 142, sp. 27. 



Hab. — Flinders, Western Pfjrt. 



Obs. — This shell was removed to Tritonidea by Mr. Adcock in 

 his list of South Australian Mollusca, but the change does not 

 seem to be warranted by the characters displayed by the shell, 

 our specimens not showing any columellar ridges or posterior 

 tubercle, nor is the outer lip thick, and it is a distinctly umbili- 

 cate shell. Triton speciosa, Angas, from Port Jackson seems to 

 be closely related generically, and also Murex borealis. Reeve, 

 but we are not yet satisfied as to the best generic position.
