Diplommatina gracilis, Beddome, P. Z. 8. 1875, p. 442, pl. hi. 
f. 2; Hanley, Conch. Ind. p. xii (index only); Theob. Supp. Cat.

Size: alt. axis 2°7 mm. 
Original description :—* Shell dextral, narrowly ovate, straw- 
coloured, not rimate ; whorls 63, all except the apical or two upper 
ones rather distantly and prominently costulated, interstices smooth ; 
spire rather slender, the fifth whorl the largest and projecting a 
little more than the penultimate, the penultimate with the con- 
striction over the centre and right centre of the aperture; aperture 
reniform; peristome continuous round the penultimate whorl, 
prominently angled, below the tooth double, the outer lip expanded 
and reflexed, columellar margin nearly straight, the tooth promi- 
nent, a little deflexed: total length $ inch. 
‘*Gudam Hills, Vizagapatam, 3000 feet elevation, 17° N, lat.” 
I notice a variety of this shell sent to me by Colonel Beddome 
from the Jeypur Hills, Madras, figured on Plate XLVI. figs. 2, 2 a. 
It has rather more tumid whorls and is less acuminate. In three out 
of eight specimens another point of difference is in the right margin 
of the peristome, which is sharply sinuate, as shown in fig. 2, The 
three specimens of D. gracilis from the Golcondah Hills do not 
show this. It is evidently only a more angulate form of the inner 
lip. 
Dretommatrna canarica, Beddome. (Plate XLVI. figs. 3, 3 a.) 
Diplommatina canarica, Beddome, P.Z.S8. 1875, p. 442, pl. Iii.

very inconspicuously rimate, flesh-coloured ; whorls 63, convex, all 
except the apical obtuse one closely, regularly, and sharply costu- 
lated ; interstices smooth ; spire conical; the fifth whorl much the 
largest, and projecting much more than the penultimate ; the penulti- 
mate with the constriction just in front of the centre of the circular 
aperture ; peristome shining, continuous round the penultimate 
whorl, slightly canaliculate in its free portion below; columellar 
margin much incurved; the tooth prominent, slightly deflexed : 
total length +4, inch.
