362 MR. E. A. SMITH ON NEW [Apr. 17, 
the name of Mr. R. F. Geale, through whose agency it was obtained 
by the Museum. 
Its most striking peculiarity is the beautifully iridescent lip, the 
predominating colours of which are green and brass. _ It is thickened 
and reflexed on all its margins. On the right-hand edge there is a 
prominent tooth, and above this a distinct deepish sinus. ‘The tooth 
on the columellar border is smaller than the other, and situated 
further within the mouth. The malleation of the body-whorl is 
most conspicuous towards the mouth and in this region the minute 
granulation is less apparent than on the upper whorls. 
Buiimus (EuryTus) ROSEOLABRUM. (Plate XXXIX. fig. 8.) 
Testa angustissime rimata, ovata, snperne acuminata, ubique mi- 
nute granoso-striata, ochracea, maculis aspersis strigisque ob- 
liquis irregulariter ornata ; anfractus 44 planiusculi, rapide 
accrescentes, ultimus magnus, antice oblique descendens ; sutura 
crenulata ; apertura ovalis, superne acuminata, intus albido- 
ochracea, longitudine teste totius 2 paulo brevior ; columella 
oblique arcuata, usque ad apicem conspicua ; peristoma roseum 
undique breviter expansum et reflecum, marginibus callo tenui 
junctis. 
Long. 42 mill., diam. 18; apertura 26 mill. longa, 14 lata. 
Hab. Malacatos, South Ecuador. 
B. piperitus of Sowerby is the nearest ally of this species. From 
that form the present one differs in being smaller and consisting of a 
whorl less. The granulous sculpture is also different, and does not 
display that transverse direction which is noticeable in B. piperitus. 
The brown spotting is far less abundant ; the general tint is yellower ; 
and the peristome is rose-coloured and everywhere expanded and re- 
flexed, which is not the case with Sowerby’s species, in which it is 
usually white, and scarcely shows any expansion or reflexion ; -how- 
ever, I have seen some examples of the Peruvian B. piperitus with 
a pink lip. 
Burimus (DrymMavus) ocHRocHEILus. (Plate XXXIX. fig. 1.) 
Testa ovato-fusiformis, anguste rimata, subtenuis, oblique irregu- 
lariter striata et malleata, sordide albida, seriebus (in anfr. 
superioribus 2, in ultimo 3) macularum fuscarum irregularium 
ornata; spira conica, marginibus leviter convexis ; anfractus 
7, lente accrescentes, convexiusculi, sutura vix oblique disjunct, 
ultimus basi attenuatus ; apertura oblonga, anguste elliptica, 
longitudinis totius teste 3 equans, subobliqua; perist. latius- 
cule expansum, flavidum, margine columellari reflexo, labro callo 
tenui flavescente juncto. 
Long. 37 mill., diam. 13. Apertura 20 mill. longa, 5} lata.

This species is closely allied to B. yungasensis of D’Orbigny, and 
differs from it chiefly with regard to the aperture, which is much 
longer, narrower, and differently coloured. Owing to the narrow- 
ness of the aperture, the last whorl is also much attenuated, con- .
