Variable in size. Gabb’s specimens are much larger than the type: according to 
the figure they are 18 millim. in diam., Pfeiffer’s original one being 13} wmillim.; 
Rogers's examples are 13-14, Carmiol’s scarcely 13 millim. Gabb’s specimens vary in 
colour from straw-yellow to orange ; those collected by Rogers have the upper half of 
the last whorl reddish, with fine reticulated white lines, and the lower half yellow, the 
preceding whorls being either reddish or yellow. In general size and aspect this 
species resembles H. zephyrina; but differs from it in its peristome being narrow and 
more straight above, and rapidly increasing in width towards the periphery of the 
whole shell.

Pfeiffer regards H. chrysocheila, Binney, as without doubt distinct from H. chryso- 
cheila, Shuttl.; the latter was published a year later, and the coincidence of the names 
may be fortuitous. But on comparing Binney’s descriptions and figures with Shuttle-
