“ But two perfect specimens of this shell occurred to me at Modi- 
toung, on the Prome and Tongoop road, together with Alyccus 
graphicus &e. It resembles D. pachycheilus, B., in the shape of the 
mouth, but it is distinguished by the slighter rise of the last whorl 
and by its subremote costulate sculpture, which, together with its 
rounded aperture, serves also to distinguish it from D. diplocheilus, 
B., D. pullula, B., and D. blanfordiana, B., the two latter of which 
are closely costulated, and the first named smooth.” 
DIPLOMMATINA HENZADAENSIS, n. sp. (Plate XLVI. figs. 6, 6 a.) 
Locality. Kyoung Gyoung Nulla, Henzada, Pegu. 
Shell dextral, ovately turreted, scarcely rimate ; sculpture rather 
distant, fine ; spire, sides convex, apex blunt ; suture well impressed ; 
whorls 6, rounded, the antepenultimate the largest, the constriction 
being just above the upper outer margin of the peristome ; aperture 
circular ; peristome double, continuous, solid for size, columellar 
tooth well developed. 
Size: major diam. 1:0, alt. axis 1-6 mm. 
KS 0:04. 242 0707 meh. 
There is only one specimen in Mr. Blanford’s collection ; but as 
it is fully grown, though so very minute, and is so unlike any thing 
before described from Pegu, I have ventured on figuring and 
naming it.
