118 LAND SHELLS OF VICTORIA 



Whorls including protoconch five, convex. Sutures impressed. Sculpture 

 consisting of very close, lightly curved axial riblets, approximately two 

 hundred on the ultimate whorl. Interstices possessing very few growth lines 

 reticulated by dense microscopic spiral striae, a feature visible only under 

 high magnifying power. Umbilicus wide, about one third of the greatest 

 diameter of the shell, exposing all the earlier volutions and the very fine radial 

 sculpture. Aperture roundly- lunar. Peristome thin, sharp. Inner lip with 

 definite callus glaze, concealing numerous riblets. 



Size of Type — Maj. diam, 4-3; min., 3-9; alt., 2 Omm. 



Localities.-^Tyve. Mount Feathertop, 6,136 feet (C. Oke) ; 

 Mount Iligginbotham, 6,000 feet (C. Oke). 



Observations. — Two paratypes with colour bands barely dis- 

 cernible are in the collection of the writer. The species some- 

 what resembles C. albanensis, Cox, from which it may be separa- 

 ted by its finer sculpture and flatter form. I have much pleasure in 

 associating with this interesting novelty the name of Mr. C. Oke 

 who has rendered such valuable assistance in the collecting of 

 these puzzling land forms. Type in the collections of the National 

 Museum of Victoria. Reg. No. F. 1058. 



Cltaropa colliveri sp. nov. (PI. 9, Fig. 4.) 



Shell small, light brown, thin, perforated, spire lightly raised. Sculpture 

 distinct. Whorls including protoconch four and one half, ornamented with 

 prominent, subeqnidistant, slightly curved radial ribs about sixty on the 

 ultimate whorl which is descending considerably below the level of the penulti- 

 mate. Interstices with few microscopic growth lines and crowded concentric 

 stria?. Sutures impressed. Entering the extremely narrow umbilicus the radial 

 sculpture is cleai'ly perceptible. Aperture oblique, rotundly lunate. Peristome 

 thin and sharp. Inner lip with callus glaze concealing several of the ribs. 



Size of Type. — Maj. diam., 2-5; min., 22; alt,, l-2mm. 



Localities. — Type under logs at end of north arm Lakes 

 Entrance (Self); Snuff Gullv near Lake Tyers and Buchan 

 (Self). 



Observations. — With no Victorian species could this be con- 

 fused. It somewhat approaches //. coclilidhim Cox from Clar- 

 ence River, New South Wales a species with fewer ribs and a 

 comparatively wide umbilicus. The colour is not constant, one 

 specimen in the cabinet of the writer being almost white. In 

 connecting the name of my friend Mr. F. S. Colli ver with this 

 beautiful little shell, it is done so in appreciation of his enthusiasm 

 and work on Victorian conchology. Type in the collections of the 

 National Museum of Victoria. Reg. No. F. 1060. 



(Jharopa inexpectata sp. nov. (PI. 10, Fig. 5.) 



Shell minute, discoid, depressed, umbilicated, fragile, white, silky. Whorls, 

 including protoconch four, rounded. Sculpture consisting of equidistant, 

 fine, radial riblets to the number of one hundred and ten on the ultimate
