Show 362 MR. E. A. SMITH ON NEW [Apr. 1 7, 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. BULIMUS (EURYTUS) ROSEOLABRUM. (Plate XXXIX. fig. 8.) Testa angustissime rimata, ovata, snperne acuminata, ubique minute granosostriata, ochracea, maculis aspersis strigisque ob-liquis irregulariter ornata; anfractus 4\ planiusculi, rapide accrescentes, ultimus magnus, antice oblique descendens ; sutura crenulata ; apertura ovalis, superne acuminata, intus albido-ochracea, longitudine testce totius || paulo brevior; columella oblique arcuata, usque ad apicem conspicua ; peristoma roseum undique breviter expansum et reflexum, 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 reflexed, which is not the case with Sowerby's species, in which it is usually white, and scarcely shows any expansion or reflexion; however, I have seen some examples of the Peruvian B. piperitus with a pink lip. BULIMUS (DRYM^EUS) OCHROCHEILUS. (Plate XXXIX. fig. 1.) Testa ovato-fusiformis, anguste rimata, subtenuis, oblique irregulariter striata et malleata, sordide albida, seriebus (in anfr. superioribus 2, in ultimo 3) macularum fusearum irregularium ornata; spira conica, marginibus leviter convexis; anfractus 7, lente accrescentes, convexiusculi, sutura vix oblique disjuncti, ultimus basi attenuatus; apertura oblonga, anguste elliptica, longitudinis totius testce | cequans, subobliqua; perist. lalius-cule expansum, flavidum, margine columellari reflexo, labro callo tenui flavescente juncto. Long. 37 mill., diam. 13. Apertura 20 mill, longa, 5^ lata. Hab. Malacatos, South Ecuador. 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 narrowness of the aperture, the last whorl is also much attenuated, con- |
