only. 
This species differs from most of the others in its sculpture. 
Depressed, spire a little elevated, coarsely granulate, no hairs, 
mouth large, open, lip thin, a little reflected, umbilicus narrow^, 
dcep.^ It Is much more like a Chloritis than any other member 
of this scries, but Hedley has classed it from anatomical data 
with the Xanthomclon series, while the Chloritid molluscs, by 
the same criterion, go with the Hadra group. The surface is 
complete granulose but there are no vestiges of hairs so that it 
apparently has no relationship with Chloritis, notwithstanding 
the resemblance. At present it seems best to indicate its pecul- 
iarities by a subgeneric name only, Baccalena nov.

The specimens thus recorded are closer to elderi, as would 
be expected, than to wilpenensis, from which they are easily 
distinguished by their much finer sculpture. 
Shell small, moie elevated than typical Pleuroxia^ sculpture 
of ridges much more numerous and better defined, 'coloration 
uniformly golden brown, apical whorls apparently smooth, but 
may be finely granose. Whorls four and a half, the last descend-
