Helix resplendens, Phil., Zeits. fiir Malak., 1846, p. 192.
Nmina [Macrochlamys) resplendens, Nevill, I. c., p. 16.
This species was found abundantly at Bham6 and in the 2nd Defile of the
Irawady. The specimens are quite undistinguishable from others in the Indian
Museum from Mergui (typical locality).- I think it doubtful if Godwin-Austen’s
N . atricolor from the Shisha Yalley will prove really distinct.
The figure in the Con. Indica, pi. v, fig. 4, is not characteristic of the species;
it appears rather to represent N. vitrvnoides.

A single specimen of this well-marked species was found at Bham6. In the
Indian Museum there are specimens of this species from Pegu, Arakan, and
Mergui. . , , >

Nmina (Dmgella) honesta, var. mdersonima, Nevill, I. c., p. 16.
This species a good deal resembles an Assam form; its thicker and more shining
substance, less open perforation, less oblique peristome (which is considerably more
broadly reflected, nearly covering the perforation), and its possessing a whorl less
will, however, distinguish it. Typical iV. honesta, so admirably figured in the Con.
Indica, pi. xc, fig. .10, is found at Pegu, Moulmein, and Thyet-Myo; var. ander-
soniana at Thyet-Myo, Sibsagar, Naga and Khdsi Hills, Chittagong and East
Cachar; Dr. Anderson also found it at Ava, in the 2nd Defile (Irawady) and at
Ponsee and Nantin. This variety is distinguished by its less depressed shape. I t is
scarcely, if at all, angled at the periphery (the angulation being very distinct in the
type form), the peristome not quite so broadly reflected over the perforation ; the
substance and texture, perforation, shape of the aperture, and number of whorls are
identical.

A few specimens were found in the 2nd Defile below Bhamò and also at Ponsee
in Yunnan. The outer tooth of the aperture varies slightly in shape. This species
seems to be allied to the Sesara group.

A single specimen only was found at Bhamò. The differences between thè
sub-genera Kaliella and Microcystis appear to be not yet sufficiently characterized.
