slope uniformly convex; posterior concave, just below the 
apex, then barely convexly sloping to the margin. Summit

Locality.—300 fathoms, off Cape Jaffa, 31 examples,

Diagnosis from Helcioniscus illibrata, Verco.—It is less” 
solid, has a curved apex, flat base, axial lire, no colour mark- 
ings. 
Obs.—I have called this little shell provisionally a Scu- 
tellina, because its apex is directed away from the opening of 
the muscle-scar; though its summit is nearly central. Its 
specific name indicates its bald apex.

‘Shell minute, thin, depressed conic. Nae single, Aes 
central, slightly anterior, directed slightly away from the 
opening of the muscle-scar. Base level, oval, somewhat nar- 
rowed anteriorly. About eighteen very low, rounded, scarcely 
perceptible ribs or radial undulations, and microscopic accre- 
mental strie. Internal surface radially scratched. The rik~ 
are ornamented with opaque white radii, rather wider than 
the diaphanous interspaces. 
Dim.—Height, 2°2 mm.; maj. diam., 33 mm.; min. 
diam., 2°4 mm. 
Locality.—Moonta Bay, Spencer Gulf; collected in num- 
bers in shell sand by Mr. A. Zietz. Several individuals were 
in Tate’s collection, labelled “Scwtellina, sp., S.A.,” in the 
same tube as shells which I lately described as Nacella crebri- — 
striata. So probably the locality of WV. crebristriata is also 
Moonta Bay.
