Type locality.
"On the high open grassy country of the West Khasi Hills".
Types examined.
Khasi Hills, coll. Godwin-Austen, NHMUK 1903.7.1.381/1 (syntype, mixed lot with
B. delibrata
: NHMUK 1903.7.1.381/2).
Additional material examined.
Khasia Hills, 183, Assam, coll. Godwin-Austen, NHMUK 20191130/1 (1 shell, mixed lot with
B. foveata
: NHMUK 20191130/2).
Diagnosis.
Shell medium-sized, dorsal side domed, greenish-yellowish with a slender main spiral band and several thinner ones; last whorl with dense hair scars (pits) only near the parietal calls, aperture almost rounded.
Description.
Shell medium-sized, rather thick-walled; depressed globular, with slightly domed dorsal side; colour greenish-yellowish, with a main but still slender reddish band just above the blunt keel and several even thinner belts on both the dorsal and ventral surfaces; protoconch consists of 1.25 whorls, with very fine radial ribs and regularly arranged hair scars; entire shell consists of slightly more than 4 whorls, separated by a moderately deep suture; teleoconch covered with a matt periostracum, dense hair scars (and short hairs near suture) visible only near parietal callus; aperture rounded/subrectangular; peristome strongly expanded and slightly reflected in direction of umbilicus; parietal part with thin, whitish, semi-transparent layer, which allows hair scars of penultimate whorl to be seen; umbilicus open, relatively narrow, funnel-shaped, with blunt peri-umbilical keel.

Burmochloritis fasciata
(Godwin-Austen, 1875), comb. nov., syntype (NHMUK 1903.7.1.381/1). For positions of close-up images see Fig.

(F = DM, G = CA, H: LV, I: PC).
Remarks.
This species was described as a variety of
B. delibrata
, but differs in numerous shell characters (smaller, more globular shell, smaller protoconch, domed dorsal side, comparatively smaller, more rounded aperture, narrower umbilicus, denser hair scars). Thus, it should be handled as a species in its own right. Moreover, based on the multiple spiral bands (
Bouchetcamaena
species have no band or a single band), this species is transferred to the genus
Burmochloritis
, although this placement requires confirmation through anatomical examination.
