ities. — 1035 ате Shelton's. Whare traverse, Block XI, 
Motumati Waterfall, Waingaromia Survey 'District, Raukumara Division 
(= S. calcar Hutton of Marshall, 1910, N.Z. Geol. Surv. Bull. No. 9 (n.s.), 
p. 22). 
This species differs from 5. callosa in its much smaller size, and narrower 
pad projecting sharply at both ends and forming deeper channels. The 
columella is also more bent to the right, and the whorls are lower. 
Struthiolaria armata n. sp. (Plate 14, fig. 4.) 
This species resembles S. spinifera just as S. callosa resembles S. spinosa. 
It has a high spire with very sloping shoulders and long strong spines on 
the shoulder-angle, 7 to 8 on the body-whorl and 6 on each of the spire- 
whorls. 
The suture is filled with a layer of callus which ascends to the tubercles 
above, while the inner-lip pad extends to about half-way between the 
tubereles and the suture, but does not quite bury the spines. The growth- 
lines are very strong, but there is no spiral ornamentation.
