“Genus Leptocollonia n.g.
Type : Leptocollonia thielei n.sp.
This is new genus is provided for a southern group of Homalopoma-like (Leptothyra) shells which differ in being umbilicate, relatively thin-shelled, colourless, and in having a distinctive operculum, which is concave externally and deeply spirally channelled. The radula of Leptocollonia is very similar to that of Homalopoma, the chief difference being in the marginals, which are plain in the former and serrated in the latter.
Thiele's Leptothyra innocens (1912, p. 192, pl. II, fig. 24) from Gauss Station, Antarctic, is a Leptocollonia, and the operculum of Leptothyra sp. (Thiele, loc. cit.), also from Gauss Station, is so similar to that of thielei n.sp. that it probably originated from this same species.”
