THE DELICATE CycLopHorus. Shell moderately exca- 
vately umbilicated, solid, white, linearly banded 
throughout with arrow-headed fulvous-chestnut dots,

Cyclophorus amoenus, Pfeiffer. 
Hab. ? 
A comparatively smooth shell, of solid growth, encircled 
with numerous close-set fillets of chestnut arrow-headed 
dots.

THEOBALD’s CycLopHorus. Shell moderately excavately 
umbilicated, depressly turbinated, solid, thick, whitish, 
copiously clouded and banded with reddish-chestnut, 
zigzag-marked towards the apex, a narrow pale zone 
at the periphery, unspotted round the umbilicus; 
whorls slopingly rounded, strongly densely grain-

Hab. Thyet-Mio, Burmah (found near the right bank of 
the Irawadi River); Theobald. 
A fine solid strongly grain-striated shell, of the same 
typical character as C. aurantiacus, from the neighbour- 
ing district of Tenasserim ; it is, however, very much less 
excavately umbilicated.

Menke’s CycLopnorus. Shell moderately umbilicated, 
depressly turbinated, rather solid, fulvous-brown or 
dark-purple, more or less obscurely zigzag-marked, 
darker banded below the periphery, whorls densely
