A very pretty, shining Glabella, its spire more elongate than fusiformis, Hinds, 

 with which it has been hitherto confounded, and as which it is inserted in our 

 Catalogue-. It is comparable with 31. alia, Wats. ("Challenger" Expedition), 

 from Cape York, N. E. Australia. 



If slightly local, it is very abundant where it occurs. The colour in the var. 

 a is a subdiaphanous golden brown or straw, and there is a very conspicuous 

 suffusion just behind the outer lip of deep rufous brown, bifurcating over the 

 labrum itself. The commoner form is var. b, larger as a rule, and pure milky- 

 white throughout, very smooth and somewhat shining. In one or two exam- 

 ples an intermediate form seems to occur, the last whorl being here white, 

 obscurely bizoned with two chestnut lines, or, indeed, occasionally trizoned. In 

 fact, it is a variable species.

A most elegant species, the tumid callous zone just below the sutures delicate- 

 ly variegated spirally with white and pale rufous, then obtusely ribbed, the 

 interstices, especially the upper row, being deeply pitted.
