from the genitive inflexion oSoutos antl srofj-a, the name slioulJ 

 be Odoutostoma which I adopt. 



5. Odontostoma Tasm.vnica. n. s. 0. testa, mimita, snb-jusca, 

 elongata conokica, tiinita, Idvissima, pollta ; apice, sinistrovHo ; 

 anfradibiis, 6-S, plcDiiiisailis ; suturis distindis ; ultimo anfrticto 

 subangidato ; apertura semi-ovata ; columella uniplicata ; lahro, 

 acuto, intus dcntato. Long. 2 mill. 



O. Shell minute elougately conoidal, turriculate, polished, 

 apex sinistral, whorls 6 to 8, somewhat flattened, suture 

 distinct, last whorl subangulate, aperture semi-ovate, colu 

 mella uniplicate, outer lip acute, and toothed within. 



I can find no ditlerence whatever between this shell and 

 the minute shell of our Upper European tertiary (0. p/iVff/?^s 

 Wood in the monograph of Crag, Mollusca synon. Tnrho 

 pUccHus Montague Testacea Britanniea, vol. 1, p. 85. Plate 

 9, fig. 3.) It is probable, however, that an extensive comparison 

 of specimens might show them to be distinct. The present 

 species was dredged up from Long Bay by Mr. Legrand. 



It should be remarked that Odontostoma is a synonym of 

 of D'Orbigny (IS-il) for Proserpina and the name should be 

 carefully distinguished from Odontostomus, separated from 

 Bulimus by Beck, in 1837. The present species seems to be 

 very near O. nitida. Alder. 



6. EuLiMA Tasmanica, n.s. E. testa mhmta, snJ)-fasca, elonrfato- 

 conoiclea, imperforata, Imvigata, polita ; apertura Integra, rotuudata ; 

 lahro incrassato ; labia refiexo. Anfractibus (G) couvexmsctdls. 

 Long. 3 mil. 



E. shell minute, dusky, elongately conoid, imperforate, 

 smooth, polished, aperture entire, rounded, outer lip thickened, 

 inner lip reflexed ; whorls 6, somewhat convex. Long Bay ; 

 6 fathoms. W. Legrand. 



This minute shell is doubtfully referred to Eulima ; but 

 there appears to be no other genus now under which it can be 

 appropriately placed. Its somewhat depressed form makes it 

 like the preceding species in shape, but it is a larger 

 shell. Under the microscope, the absence of any folds on the 

 columella, the entire or reflexed lip, readily distinguish it. 

 It is not common.
