144 PETTERD : NEW TASMANIAN SHELLS. 



short, acute, nucleus smooth, suture emarginate ; 

 aperture narrowish, 4-plicate, lip white, rounded, 

 thickened, and expanded. Long. 8 mill., lat. 5 mill. 



Habitat, North and East coasts. 



A very fine form, approaching M. muscaria and 

 M. tasmanica, but easily known from either. 



34. Marginella minima n. sp. Shell minute, pyriform, 



white, polished ; whorls 3, spire depressed, nucleus 

 scarcely exserted, suture distinct ; aperture narrow, 

 rather wider toward the anterior margin, with ten 

 plications which gradually increase in size, posterior 

 margin somewhat raised and inflated to nearly the 

 same level as apex. Long. i|^mill., lat. ^ mill. 



Habitat, Dredged off Long Bay in about 7 

 fathoms. 



A form so small may be easily overlooked, 

 although somewhat abundant. 



35. Eulima aurantia n. sp. Shell subulately elongate, 



smooth, polished, rather thin, orange colour with a 

 paler band below the suture ; whorls 9, last with an 

 indistinct paler band at the middle, suture distinct ; 

 apex white, blunt, and embryonal whorl twisted ; 

 aperture small, ovate, pointed behind ; inner lip 

 thinly reflected, outer acute. Long. 7 mill., lat. if mill. 



Habitat, North Coast. 



I have obtained several examples of this very 

 neat and distinct species. Its narrow elongated form 

 and peculiar coloration separates it from the rest of 

 our somewhat numerous representatives of the genus. 

 It is about the same size as Turbonilla fusca Angas 

 (the Elusa bifasciata of Tenison Woods) ; in colora- 

 tion it is also not unUke that species. I have seen 

 some few almost white specimens, but there is gener- 

 ally some trace of the characteristic coloration.
