166 BIOLOGY OF SNOWY RIVER AREA 



Gastropoda 



Family LIMN^IDAE 



Genus LIMNAEA Lamarck, 1799. 



Limnaea brazieri Smith. 



1882. Limnaea brazieri Smith, Journ. Linn. Soc. Lond., Zool., XVI, p. 274, 

 pi. 5, fig. 15. 



Size of Type.— Length 9 ; diam., 5 \ ; Aperture long 6 ; breadth 

 4imm. 



Type Locality.— Glebe Point, Sydney, New South Wales. 



Observations. — This shell, which is an interesting addition to 

 the Victorian fluviatile molluscs, the author describes as ovate 

 glossy, brownish horn-colour, somewhat strongly striated longi- 

 tudinally by the lines of increment, without spiral or transverse 

 sculpture. Our identification has been fasciliated by specimens 

 from the type locality sent to the National Museum from the 

 Australian Museum, Sydney. 



Locality.— 50 specimens (F 1903) dam, Banool, Gelantipy, 

 Victoria (A. Hodge). 



Limnaea gunni Petterd. 



1889. Limnaea gunni Petterd, P.R.S. Tas., p. 66, pi. 2, fig. 10 ; pi. 3, figs. 9. 



and 12 (animal). 

 1939. Limnaea gunni Petterd. Gabriel. Mem. Nat. Mus. Vict., XI, p. 108, 

 pl. 1, fig- 8. 



Size of Type. — Length, 7; breadth, 5 -5mm. 



Type Locality. — South Esk River, near Launceston, Tasmania. 



Observations. — A very thin, fragile, yellowish horn-coloured 

 shell, previously located at Tarraville. 



Locality. — 22 specimens (F 1904) swamp, Rockbank. These 

 specimens were found in a natural soak on top of the soft mud 

 between grass tussocks. 1 specimen (F 1940) Sandy Swamp, 

 Rockbank. 



Limncea sp. 



The specimens, apparently distinct from any known Victorian 

 form, are either too immature or too fragmentary for certain 

 diagnosis. 



Locality. — 13 specimens (F 1894) Little River, Rockbank. 



The Little River is a clear stream with a loose boulder bot- 

 tom on which the snails were crawling in about a foot to eighteen 

 inches of water.
