lower portion of the penultimate whorl, double in its lower free 
portion, the columellar margin semicircular, the tooth small but 
plainly visible under the lens: total length ,}, inch, 2} times the 
breadth. 
Gudam hills, Vizagapatam, with the preceding, but very rare. 
This is the smallest known species of Diplommatina true ; it is quite 
a connecting link between Semper’s genus Moussonia (Pupa pro- 
blematica, Mousson) and true Diplommatina. 
These are the first species of Hudiplommatina discovered in 
Southern India; the genus does not apparently occur on our 
western ghats south of 14° N. lat., where its place is taken by 
Nicida. Large tracts of the mountainous country in the Vizaga- 
patam and Ganjam districts are conchologically quite unexplored ; 
and other species will no doubt be some day discovered, particularly 
as Nicida is not found. On the Nallay-Mallay mountains, Kurnool 
district, 15° N. lat., I could not detect either Diplommatina or 
Nicida, though Opisthostoma was discovered; these hills, however, 
have been only superficially searched, and Diplommatinas will I 
think yet be found there. 
Dierommatina (NicIDA) ANAMALLAYANA, 0. sp. (Plate LII. 
figs. 5 and 6.) 
Shell scarcely rimate, oblong, the apex suddenly contracted, thin, 
whitish, shining; whorls 5, convex, the apical one small, obtuse, 
the second much larger, the three lower all equal in breadth (giving 
the shell a very oblong form), all smooth except the last, which has 
a very minute transverse striation, and is furnished with a basal 
keel; aperture circular ; peristome double, externally expanded, and 
reflexed: total length ;4 inch. 
Anamallays, in dense moist forests on the banks of the Perin- 
goonda river, 2090 feet elevation, rare. 
It is easily distinguished from all the other species by its very 
oblong form. 
Drietommatina (NicipA) suBovaTa,n.sp. (Plate LII. fig. 7.) 
Shell not rimate, conico-ovate, smooth, thin, shining, yellowish 
white, furnished with a subobsolete, very minute, oblique striation ; 
whorls 6, convex, the penultimate the largest, the four upper ones 
gradually tapering, the apical one obtuse, the lowest whorl furnished 
with a rather prominent basal keel; aperture obliquely oblong ; 
peristome single, not continuous round the penultimate whorl: total 
length 54, inch. 
South-Canara ghats, moist forests, 1000-3000 feet elevation. 
Allied to Nicida nitidula, Blanf., but differing in its single peri- 
stome and more prominent basal keel. 
DirtomMatTina (NIcIDA) PEDRONIS, 0. sp. (Plate LIT. fig. 8.) 
Shell subcylindrico-ovate, prominently rimate, thin, smooth, of a 
pale dull olive-colour; whorls 7, convex, the antepenultimate the 
largest, the four upper ones gradually decreasing, the seventh or
