THE FRESHWATER MOLLUSCA OF VICTORIA 
Ske. — Length, 2 5 mm.; breadth, 15 mm. 
Localities. — ^Western Port (Type) ; Gippsland (Nat. Mus. 
Melb.) ; Merri Creek (W. Kershaw) ; Lake Connewarre (F. 
8. Colliver) ; Werrihee R. (R. Hall) ; Queenscliff (J. A. 
Kershaw) ; Lake Gnotuk ( J. Searle) ; Geelong (J. Mulder) ; 
Port Albert, Lakes Entrance, Longford, Tarraville, Dromana, 
Frankston (T. Worcester) ; Moorabool R. (J. H. Young) ; 
Colac (Rev. G. Cox) ; Portland (W. H. Dillon) ; Merri Creek, 
Coburg (Mrs. W. Hanks) ; Merri R., Warrnambool. 
Vernacular Name. — The Whelk-like Bythinella. 
Observations. — An extremely variable species, approaching 
B. nigra, but distinguished by its shorter spire, more inflated 
whorls and a rounder mouth. The following is Quoy and 
Gaimard’s original description: “Paludina, testa minima 
ovato-conica, apice siihacuta; laevi, flavescente, vitta fulva 
hicincta; anfractibus senis, convexis; apertura ovali” ; the 
authors remarking that all specimens were dead shells col- 
lected in brackish swamps at Westernport. Smith, under the 
name of Ilydrobia angasi, described a form from the Com- 
pasely River (Campaspe), which I consider is merely a 
variant of buccinoides, slightly broader in contour, but 
otherwise inseparable. This form has been noted from 
several districts throughout the State. Specimens of BytJii- 
nella from a shell-bed underlying volcanic tuft near Warr- 
nambool were determined by Chapman and Gabriel as nigra 
Q. and G. ; but re-examination of this material forces us to 
change our opinion and to accept buccinoides Q. and G., as 
the correct nomination. In several localities specimens are 
more or less carinated, but less so than B. nigra. Like nigra, 
buccinoides is frequently coated with decaying vegetable 
matter. 
Bythinella grampianensis sp. nov. 
(PI. I, Fig. 5.) 
Shell minute, turbinately elongate ; whorls about 4|, much 
rounded, sutures well impressed. Aperture small, pyriform, 
continuous, inner lip reflected ; colour brown. 
Size of Type. — Length, 2 mm. ; breadth, 1 nun. 
Locality. — Dairy Creek, near Silver-Band Falls, Gram- 
pians. Collected by F. E. Wilson. 
Vernacular Name. — The Grampians Bythinella. 
Observations. — A very small species with much rounded 
whorls. Its nearest ally is perhaps the Tasmanian Hydrobia
