MONTACUTA DROMANAENSIS, Gatliff and Gabriel. 

 P.R.S., Vic, 1912, Vol. XXV., p. 167, PI. IX., figs. 1-4. 

 Several specimens from Sulphur Creek, near Penguin. 



CYAMIOMACTRA COMMUNIS, Hedley. 



P.L.S., N.S.W., 1906, Vol. XXX., p, 541, PL 31, figs. 

 11, 13. 



North Coast ; probably Tamar Heads. Collected by A. 

 Simson. 



CUNA PLANILIRATA, Gatliff and Gabriel. 



P.R.S., Vic, XXIV. (N.S.), 1911, p, 191, PI. XLVIL, 

 figs. 13-17. 



100 fathoms, 7 miles east of Cape Pillar, a fair number 

 occurred. A very similar species — or possibly variety — 

 was found plentifully off Thouin Bay, in 40 fathoms. I 

 think it very doubtful if it is correctly placed in Cuna. 



PRONUCULA DECOROSA, Hedley. 



MA. Mus., IV., pt. 5, 1902, p. 290, fig. 39. 



Several specimens from off Pilot Station, in nine fathoms, 

 seem a variety of this. In our shells the radiating ribs are 

 less pronounced. 



PL VIII., fig. 42 and 42a, 



GLYCIMERIS AUSTRALIS, Quoy and Gaimard. 



Voy. Ast. III., 1835, p. 469, PL 77, figs. 7-9. 



Valves occurred at Forsyth Island, Furneaux Group. 

 Our shells are well represented by Reeve's figure of P. 

 flammed, Conch. Icon., PL XL, fig. 7, which is possibly dis- 

 tinct from G. australis. 



ARCOPERNA SCAPHA, Verco. 

 T.R.S., S.A, Vol. XXXII., 1908, p. 196, Pi. XII., figs. 

 1-5. 



40 fathoms, off Thouin Bay ; a few single valves. 



MYODORA SUBALBIDA, Gatliff and Gabriel. 

 P.R.S., Vic, July, 1914, p. 96, PL XV., f. 14. 

 100 fathoms, 7 miles east of Cape Pillar; a single valve. 



SOME OBSERVATIONS ON DISTRIBUTION, ETC. 



CALLOCHITON INORNATUS, Ten.-Woods. 

 Until lately this species was only known from our North- 

 West Coast, but it has recently been found in considerable 

 numbers, and of large size, in Port Arthur and D'Entre-
