HORN EXPEDITION-MOLLUSCA. 
Colour. —A rich lirown fibove and on the sides, base straw-coloured, sonietiines 
with a faintly green tinge. 
Sculphtre. —The embryonic whorls are immersed, except a quarter of a turn, 
which is smooth ; the surface of the first spire-whorl is ornamented with quincun- 
cially-arranged granuh'S merging with tlie revolution of the spire into tlie 
prevailing ornament, which consists of crowded, elevated scales arising from 
elongate, granular bosses arranged more or less coincidently with the slightly- 
arched inconspicuous ridges and lines of growth. Worn surfaces present the 
appearance of elongated granulations, and in this respect recalls Chloritis viciorico 
and Badistes evandaleana. 
Dimensions. —Basal diameters, 15 and 12-5; height, 9’5; height of last whorl, 
7'25 ; width of umbilicus, 3. 
Affinities. —This species is congeneric with Chloritis pseudoprumim and 
C. coxeni, as determined by identical characters presented by the early whorls of 
each. In shape it is somewhat intermediate between C. Victoria;, Cox, and 
Badistes evandaleana, Angas, and to which it is allied by ornameirt, except that 
the granulations are not setiferous. C. Victoria; is distinguished by more gloliose 
shape, inflated body-whorl and small umbilicus; B. evandaleana is more depressed 
and the last whorl is obtusely carinated. 
Locality. —Moderately abundant under rocky ledges in Palm Creek and its 
branches, Krichauff Range. 
Note. —The species-name, squamulosa, has already been employed in the genus 
Helix (in its old acceptation), but as I had used it restrictedly to Thersites and 
now to Chloritis, it should not be regarded as a double employment, the original 
Helix squamulosa being transferred to Etilota. If, however, my ruling is not 
acceptable, I suggest in substitution the name aphioderma. 
Genus Thersites.

“ The South Australian expression of the Badistes type,” writes the founder 
of this section, “are depressed, keeled Badistes, with corrugated surface.” Tliis 
definition should be extended not only to bring two of the four sjiecies which he 
enumerates into the group but also to embrace others now herewith associated. 
Briefly, the section may be retained for the sculptured Badistes, but that definition 
will exclude T. hoivardi, which has the lenticular shape of T. kooringensis, but is
