Read 13th December, 1901. 
Trersires (Raacapa) Woopwarpt, n.sp. 
Shell imperforate, depressed globose, solid, white throughout, with 
indistinct oblique striz or lines of growth, interspaced on the last half- 
whorl by microscopic, close-set, waved lines; whorls 53, moderately 
convex, obsoletely keeled at the termination of last whorl; suture 
simple; umbilical region very slightly depressed; peristome rather 
broadly expanded, margins connected by a thin callus. Diam. maj. 
22, alt. 15 mm. 
Thersites Woodward, u.sp. 
Hab.—N.W. Australia (B. H. Woodward). 
Compared with 7. convicta (Cox) the present species is much more 
compressed in form, the peristome is more expanded, the whorls 
increase less rapidly, and the apex is more prominent. 
The type-specimen of Z. Woodward? is only slightly keeled towards 
the front of the last whorl, but in another example the whole of the 
last whorl is keeled, while a third one shows hardly any indication of 
a keel. 
Named in honour of Mr. Bernard H. Woodward, Director of the 
Perth Museum, West Australia, from whom the specimens were 
received,
