(Pfr.) and Achati'iiella (s. str.) agree with each other, and with the 
description given by Heynemann, Mai. Blatt. 1869 ; those of Newcombia 
and Laminella show, on the contrary, the usual type of the Helicince, but 
the central tooth is quite narrow ; the jaw arcuate, without ribs, and 
thickest on the cutting edge. The species of the sub-genus Leptachatina 
agree with them in the jaw and central and lateral teeth, but the re- 
flected apex of the marginal tooth is simply bi- or tri- dentate in Lami- 
nella and Neiocofubia, and bluntly digitate in Leptachatina, somewhat as 
in Partiila. Bland & Binney, Ann. Lyc. N. York, x. pp. 331-337, pi. xv.
