LAND SHELLS OF VICTORIA 113 



Genus MISELAOMA Iredale, 1933. 

 Miselaoma sinistra, (Gabriel). 



1930. Laoma sinistra Gabriel, P.R.S., Vic, XLIII, (N.S.), pt. 1. p. 81, pi. 2, 



fig. 8. 

 1937. Miselaoma sinistra (Gabriel), Iredale, Aust. Zool., VIII, p. 316. 



Size of Type. — Maj. diam., 10; min., 1-0; alt, 12mm. 



Localities. — Tarraville (Type, T. Worcester) ; Ferntree Gully 

 (C. Oke). 



Observations. — A peculiar sinistral form. In 1933 Rec. 

 Aust. Mus. XIX, p. 53, Iredale erected this genus for the recep- 

 tion of the Tasmanian Helix weldii Tenison Woods, naming it as 

 the Type, and later (loc. cit.) included Laoma sinistra mihi, 

 from Victoria. These two species are somewhat similar, the 

 Tasmanian form being a much broader shell. This interesting 

 genus is further represented by M. reevesbyi Cotton from Reeves- 

 by Island, South Australia. Type of M. sinistra in National 

 Museum, Victoria. 



Genus TROCHOLAOMA Iredale, 1937. 

 Trocfoolaoma parvissima (Cox). 



1871. Helix (Conulus) parvissima Cox, in Legrand Coll. Mon. Tas. Land 



Shells, sp. 39, pi. 2, fig. 1. 

 1879. Helix parvissima Cox. Petterd, Mon. Tas. Land Shells, p. 22, sp. 33. 

 1894. Endodonta parvissima (Cox). Pilsbry, Mon. Conch., IX, p. 34. 

 1896. Endodonta parvissima (Cox). Hedley, Ree. Aust. Mus., II, p. 104. 

 1909. Laoma parvissima (Cox). Petterd and Hedley, Ree. Aust, Mus., VII, 



p. 296. 

 1921. Id., May, Cheek-List Moll. Tas., p. 95, No. 928. 

 1923. Id., May 111., Index Tas. Shells, pi. 43. fig. 13. 

 1937. Trocholaoma parvissima (Legrand). Iredale, Aust, Zool., VIII, pt. 4, 



p. 316. 



Size.— Maj. diam., 0-05; min., 0*04; alt., 0-06 of an inch. 



Localities.— Victoria (Iredale) ; Trentbam Falls (J. K. and R, 

 C. Gabriel). 



Observations. — A minute, conical species not comparable with 

 any Victorian form. The Trentbam record is based on two frag- 

 mentary specimens found in moss near the falls and although a 

 trifle smaller, thev appear to represent the series. The author's 

 locality is near Brown's River, Tasmania, but is generally dis- 

 tributed throughout the island. It is also recorded from Mt. 

 Kosciusko, New South Wales. Helix spiceri Petterd from Tas- 

 mania is selected as the type of the genus.
