FULTON: STJiEPTAXIS, PLAXISPIBA, CHLOUITIS, N.SPP. 



323 



Similar in form, colour, and position of its spiral bands to P. atacta, 

 Pfr., but readily separated bv its smaller size and prominent oblique 



striae. In atacta the striae are very inconspicuous and might be 

 described as growth-lines, whereas in suhatacta they might be termed 

 very thin, closely set costae. 



Chlokitis verrucosa, n.sp. 



Shell depressed-globose, rather thin, dark brown ; whorls 4, 

 covered with irregularly disposed liair-scars, first whorl minutely 

 and closely pitted, the next two with oblique, somewhat raised 

 flexuous striae, the last whorl conspicuously corrugated ; umbilicus 

 moderately open and deeply excavated, broadening out above and 



• 



prominently keeled ; aperture oval, dark within ; peristome thin, 

 light brown, sliglitly expanded, nuirgins connected by a thin callus. 

 Max. dimensions — width 13, height 7 mm. 



Hah. — Sierah Island, Tenimber Group. 



A very distinct form, easily distinguished by its corrugated surface. 

 Althougli but few hairs remain, it is probable that in life the shell is 

 covered with them, and that they fall off after death.
