These specimens average about 9 mm. in length, and 

 show little variation in size. They agree well with the 

 description given by Spencer and Hall and Sayce of this 

 species, which was collected by them in Central Australia, 

 and is known also from various other localities in Victoria, 

 New South Wales, South Australia, etc. 



Spencer and Hall divided the species into three varieties, 

 stating that although the extreme forms of these were clearly 

 distinct, there were intermediate forms which rendered it 

 impossible to plaoe them in separate species. The specimens 

 I have examined come nearest to their variety typica, having 

 about 24 lines of growth, which bear a few setae, the inter- 

 spaces being marked by raised lines arranged mostly in a 

 radiate manner. The colour is a dark chestnut-brown, some- 

 what lighter near the margins of the shell.

Locs. — Between Todmorden and Wantapella Swamp, 

 1 specimen (in spirit), 6 mm. long: rock hole, west of 

 Carmeena, Everard Range, 10/8/14, 2 specimens, dry, one 

 5 mm. long, the other smaller. 



These specimens are much larger than those referred 

 below to L. eremia, and in size, shape of shell, etc;., appear 

 to belong to King's species, which has been recorded from 

 various places in Victoria and New South Wales, but the 

 material is so scanty and imperfectly preserved that I am 

 not certain of the identification.

Locs. — Carmeena, rock hole, Everard Range, 14/8/14, 

 many specimens; flat rock hole, 30 miles east of Musgrave 

 Ranges, 16/7/14, several specimens. 



These specimens vary somewhat in size, but average 

 about 4 mm. in length, and in size, colour of shell, structure 

 of the rostrum, etc., agree with the description given by 

 Spencer and Hall from specimens collected by them at Cooper 

 Creek, Central Australia. This is the only locality given by 

 Sayce in 1903, so that the record of them from the localities 

 near the Everard and Musgrave Ranges is an extension of 

 their distribution.
