184. Etjlima atjstralasiaca, sp. n. (PI. 10. fig. 7.) 



E. testa fusiformi, politissima, crassiuscula, pauUum incurva ; 

 anfractibus 10-11, condensatis, lacteis, apud suturas pauUulum 

 impressis, ultimo anfractu crasso, varicibus obsoletis ; apertura 

 ovata, peristomate prsesertim apud basim, incrassato, Isevissimo. 

 Long. 7, lat. 3 mm. 



A very shining, polished, milky- white, opaque EuUma, fusi- 

 form, slightly incurved, ten- or eleven-wLorled, apex small ; 

 whorls very slightly impressed at the sutures, the last whorl 

 thickened, especially towards the base ; aperture oval ; peristome 

 thick, exceedingly smooth. 



This species slightly resembles E. latipes, "Watson, collected 

 at Minders' Passage, Torres Straits, in 7 fathoms, during the 

 ' Challenger ' Expedition, but is much larger in every part, and 

 the spire does not so rapidly contract. The aperture, too, is large 

 proportionately. The lateral varices are quite inconspicuous or 

 obsolete.

186. Obeliscus terebelloibes, A. Ad. 



Possibly a variety, but, if so, a very remarkable one, of 

 O. dolabrata, L., being much narrower in proportion, more 

 numerous in the whorls, with the columellar plicae but two an 

 number.
