conical, beneath depressly-convex ; base -whitish, gradually on the 

 penultimate whorl tinged with violet, afterwards violet, then reddish, 

 with the apex whitish, under the lens radiately plicately-rugose, last 

 whorl with numerous obsolete spiral lines ; spire obtuse at the apex ; 

 whorls 5, flatly slightly convex ; aperture oblique, lunate ; peristome 

 white, slightly thickened, very briefly expanded, columellar junction 

 below somewhat angularly rounded. Operculum reddish-horny. 



Diameter, greatest 0'23 ; least 0-20; height 0'20 of an inch.

 Masters and Brazier. Pine Mountain, Lismore, Eichmond River, on 

 leaves and trunks of trees. MacGillivray. 



Closely allied to IT. Dragtonensis. A variable shell in colour ; it fre- 

 quently has a dead and chalky, instead of a porcellaneous, appear- 

 ance, and the red and violet of the spire are sometimes greenish, or 

 bluish, or altogether wanting ; the throat is occasionally reddish or 

 yellowish, instead of white. My Queensland specimens are not 

 generally so brightly coloured as a series from the Eichmond.

Although I have two specimens sent me by Cuming under this name, 

 and they agree with the description, yet I have preferred to give 

 Pfeiffer's account, merely adding the colour of the operculum, which 

 is present in one of the two.
