Show 1877.] SOUTH-AMERICAN HELICIDAE. 363 siderably more so than in D'Orbigny's species, which was obtained in Bolivia more than a thousand miles south of where the present form was collected. The transverse brown spotting appears rather like interrupted bands than series of spots. These are connected by opaque white lines ; and the uppermost series is the narrowest. The lines of growth are rather coarse towards the labrum, which shows the yellow colour of the interior on the outside. BULIMUS (DRYMJEUS) ^QUATORIANUS. (Plate XXXIX. fig. 7.) Testa umbilicata, ovato-acuminala, tenuis, minutissime spiraliter striata, incrementique lineis sculpta, lutescenti-albida, strigis nigro-fuscis latiusculis subfulguratis longitudinaliter strigata spira conica, apice acutiuscula ; anfr. 6 parum convexiusculi, ultimus magnus, aliquanto inflatus, breviter ascendens; apertura ovalis, intus pallide lutescens, strigispellucentibus, longitu-dinis totius \ paulo superans ; peristoma tenue, late expansum., extrinsecus et intus rosaceum, margine columellari late reflexo. Long. 26| mill., diam. 11; apertura extrinsecus 14| longa, 9| lata. Hab. Ecuador. The species here described has been confounded with B.fucatus of Reeve, and was so labelled in the Cumingian collection. The type of that species, with the majority of all the others described in the late Mr. Lombe Taylor's collection having been most liberally presented to the British Museum by Mrs. L. Taylor, has enabled me to compare the two forms; and certain differences are observable which appear sufficiently constant to distinguish them. In the first place, Reeve's species is from New Granada, and the present one from Ecuador. It is also larger than the former, has the body-whorl more inflated, the aperture is longer than half the entire length of the shell, whereas it is less in fucatus ; the peristome is more inflated, and the coloration is different. BULIMUS (DRYM^EUS) ALBOLABIATUS. (Plate XXXIX. fig. 4.) Testa ovato-fusiformis, anguste (fere obtecte) perforata, tenuis, transversim obsolete striata, incrementique lineis obliquis sculpta, fusco-albida, strigis latis obliquis nigrescentibus vel purpureo-nigris fulguratis et fasciis interruptis ejusdem coloris (in anfr. superioribus 2, in ultimo 3) ornata; spira elongata, conica, lateribus leviter convexis ; anfract. 6|, convexiusculi, infra suturam leviter constricti, ultimus circa basim extraque labrum linea rufescente ornatus; apertura inverse auriformis, subverticalis, intus lilacea, strigis fasciisque pellucentibus, longit. totius paulo minor ; peristoma tenue, extrinsecus et intus album, sub-late expansum, margine columellari reflexo, intus tortuoso. Hab. Malacatos, South Ecuador. The nearest ally of this handsome species appears to be B.fusoides of D'Orbigny, which, however, is a much more elongated species, without transverse interrupted bands, at all events in the typical form, and with a rosy lip to the aperture. |
