These specimens differ from the type in having only very faint indications of the nodose 
plications at the upper angle of the whorls. They also differ in colour, being paler and less rosy. 
Trochus (Monilea) warnefordi, G. and H. Nevill, may be the same as this species. 
270. Ethalia rhodomphala, n. sp. (Pl. XXXVI. figs. 1, 2). III, V, X. 
Testa orbiculata, supra breviter conica, semiobtecte anguste umbilicata, ad peripheriam acute 
angulata, supra albida, maculis paucis remotis fuscis et lineis tenuissimis irregularibus undulatis 
radiatim picta, ad peripheriam maculis semipellucidis roseo pictis ornata, infra lineis albis opacis 
irregularibus subzigzagformibus variegata, circa umbilicum rosea; anfractus sex leves, nitidi, ultimus 
circa medium striis paucis sculptus, circa umbilicum radiatim plicatus; apertura oblique subquadrata, 
margaritacea, iridescens; columella crassa, in medio margaritacea, valde reflexa, alba vel rosea, callosa, 
umbilicum semiobtegens.

Viewed with the naked eye, the upper surface of this shell looks whitish with a few brown 
radiating blotches. A closer inspection with a lens, however, reveals the presence of very fine 
lineation, more or less broken up, undulating or dotted. The puckering around the umbilicus is 
pinkish, the rest of the base being covered with opaque white irregular markings upon a sub- 
translucent ground. The last whorl is angled at the periphery and above the angle is marked 
with a few distinct spiral striae.

The locality of this species has not previously been recorded. The single specimen obtained 
is of a greenish yellow tint externally and the central portion of the interior is of a somewhat 
similar colour. The anterior slit is very peculiar, being clean-cut, and extending from the margin 
almost to the apex.
