22 SMITH : LAND SHELLS FROM NEW GUINEA. 



This solid species is well characterised by the niiicli- 

 thickened and produced pellucid labrum. Two specimens 

 have been presented to the British Museum by Herr 

 Strubell.

Hclicina soliiavia, Smith, Ann. Mag. Nat. Hist., 1887, vol. 

 xix., p. 425, pi. XV., f. 10 (not good!). 



Hab. : Eafa district, between Mounts Alexander and Bellamy, 

 at an elevation of from 5,000 to 6,000 feet. 



Several fresh specimens show that the colour is somewhat 

 variable. The general ground-colour is opaque-white, sometimes 

 varied with a spiral purple-red zone upon the middle of the 

 upper surface of the whorls, or with some irregular spots or dots 

 of the same colour. The apex is generally opaque pale yellow, 

 and the two succeeding whorls are rich purplish red. A faint 

 second zone is often traceable beneath the opaque white surface 

 upon the base of the body- whorl. The labrum is bright yellow 

 or orange, and the interior of the ap(n-ture is of a very dark- 

 purplish red tint. The umbilical callus is generally yellowish, 

 but occasionally pale and glossy. 



A single specimen is opaque white above, with scattered sub- 

 hyaline wavy streaks and spots. The apex, however, is of the 

 same opaque character, and conspicuous, as in the other specimens. 

 H. dentoni, Pilsbry, appears to be the same as this species.
