122 LAND SHELLS OF VICTORIA 



to indicate the wide distribution the species enjoys in Victoria. 

 It is certainly one of the most frequent of our smaller forms. Thu 

 species has been placed by Iredale in his genus Pillomena, Rec. 

 Aust. Mus. XIX, p. 54, 1933, a genus erected by the author with 

 Flammidina meraca Cox and Iledley, as the Orthotype. 



AUodiscus niveus Iledley. 



1896. Endodonta nivea (Iledley), Rec. Atist. Mus., ii, p. 102, pi. 23, figs. 5-7. 



Size of Type. — Maj. diam., 3-25; min., 2-75; alt., l-5mm. 



Locality. — Wombargo Creek, Wulguhnerang (Nat. Mus. Vic), 

 4,000 feet. 



Observations. — A small, white, thin, shining shell possessing a 

 narrow perforation. Whorls are three, the last being "crossed by 

 115 sharp costse." It is a characteristic species and with its few 

 whorls should be easy to recognize. The author remarks "This 

 species nearly approaches E. antialba, Beddome from Tasmania 

 from which its narrow umbilicus and shallow spire readily dis- 

 tinguishes it." Type locality Mt. Kosciusko, New South Wales. 



AUodiscus marysvillensis, sp. nov. (PL 10, Fig. 8.) 



Shell minute, white, discoid, umbilicated. Whorls including protoconch 

 four, rounded. Sculpture extremely fine, consisting of subequidistant radial 

 ribs, about one hundred and seventy on the last whorl. Interstices reticulated 

 with fine growth lines and microscopic spiral stria?, in the case of the former 

 an average of four to five. Sutures impressed. Umbilicus moderately wide, 

 about one cpiarter of shell's greatest diameter, with the volutions well exposed 

 showing distinctly the radial sculpture and the concentric sculpture of the 

 protoconch. Aperture rotundly lunate. Peristome simple, sharp. Inner lip 

 not reflexed ; parietal wall with a thin white glaze covering several of the ribb. 



Size of Type.— Maj. diam., 2-3; min., 2-0; alt., l-0imn. 



Localities.— Type. Marysville (near Wolfram mine) under 

 decaying timber (Self); Gembrook, and Paradise Palls near 

 Whitfield (Self). 



Observations. — A most delicate and beautifully closely ribbed 

 species and the smallest of the genus in Victoria. Its affinity 

 would seem to lie with H. gadensis Beddome from Tasmania. It 

 is a slightly taller shell and examination of the protoconch reveals 

 a distinguishing character where the sculpture is extremely fine. 

 In the novelty about twenty spirals appear, being three times as 

 numerous as in the Tasmanian form. Type in National Museum, 

 Victoria. Reg. No. P. 1066.
