54 A MONOGRAPH OF 



Obs. — ^Young shell turreted, apex acute ; whorls 8, swollen, 

 ribbed above, last obtusely-angled. 



Length 0*25, breadth 0-09 ', aperture about 0*07 of an inch. 



Habitat. — Port Lincoln, South Australia ; islands in Bass Straits. 



Obtained in vast quantity at high- water mark with the preceding, 

 and with it used by the islanders for making necklaces, which are sent 

 in great numbers to Launceston and Hobart Town for sale. The making 

 of the necklaces of these shells and a small species of Elenchus, E. 

 irisodontes, is one of the principal means of support of the half-caste 

 aboriginal people living upon the islands in the Straits. 



4. — Truncatella micra — Tenison-Woods.

Shell minute, white, translucent, cylindrical ; whorls 4 (decollate), 

 irregularly costately striate, inflatedly convex ; suture impressed ; aper- 

 ture small, semi-lunar, outer lip reflexed.

Habitat. — Brighton, Victoria (Kershaio) ; Furneaux Group, Bass 

 Straits. 



" There are so many Truncatellce described which run so closely to 

 each other that I hesitate to add this species. It seems, however, to 

 differ widely enough from all known to me to warrant my giving it a 

 name." — Woods. 



The shell corresponding to the above description is very plentiful at 

 the locality mentioned, but I cannot see any specific difference between 

 it and the preceding species. The species described are so much alike 

 that new species should be very cautiously accepted ; in fact, I must 

 -admit that I cannot separate them with any satisfaction.
