Catalogue of the Marine Shells of Victoria. 89 



Hab.-Deep water, Port Phillip Bay (J. B. Wilson). 



Obs. — Professor Tate states that this species is at once distin- 

 guished by its size, its furrowed suture, and the flat distant ribs 

 on the base, at the same time he notes that its nearest ally is 

 Diala lauta, A. Adams. We must remark that for our own part 

 we feel somewhat dubious about the validity of this species, and 

 are somewhat inclined to regard it as an exceptionally large 

 specimen of Diala lauta. 



Diala pagodula, A. Adams. 



1862. Alaba pagodula, A. Adams. A.M.N.H., vol x., 



3rd ser., p. 297. 

 1887. Litiopa (Alaba) pagodula, Tryon. Man. Conch., 

 vol. ix., p. 282. 

 Hab. — Common in Port Phillip. 



Obs. — Rissoina St. Clarae, Tenison Woods, P.R.S. Tas., 1877, 

 p. 15-i, No. 67, is, we think, from the description, the above 

 species ; it most certainly is a Diala. 



Diala pulchra, A. Adams. 



1862. Alaba pulchra, A. Adams. A.M.N.H., vol. x., 3rd 



ser., p. 296, No. 15. 

 1837. Litiopa pulchra, Tryon. Man. Conch., vol. ix., p. 

 282. 

 Hab. — Port Phillip ; Western Port. 



Obs. — The type of this species is recorded as from Port 

 Adelaide, and is noted as being a handsomely painted species 

 with the whorls nodosely plicate at the sutures. We have shells 

 which apparently represent this species, but we are much inclined 

 to think it is only a form of D. pagodula, A. Adams, examples of 

 which we have strongly nodosely plicate, at the sutures, faintly 

 nodosely plicate, and some, which appear evidently the same in 

 all other respects entirely without any nodosities. 



Diala varia, A. Adams. 



1861. Diala varia, A. Adams. A.M.N.H., vol. viii., 3rd 



ser., p. 243. 

 1887. Litiopa varia, Tryon. Man. Conch., vol. ix., p. 

 282. 

 Hab. — Western Port ; Puebla Coast.
