Show 1875.] MR. S. HANLEY ON NEW INDIAN SHELLS. 605 4. Description of new Land and Freshwater Shells from India. By SYLVANUS HANLEY, F.L.S. &c. [Received September 20, 1875.] The first two of these fine shells were collected by W. Theobald, my coadjutor in the * Conchologia Indica,' and have been figured, but not described, in that publication. As the specimens were unique, they have been retained for some years in the hope of obtaining other individuals ; for the common practice of describing from single specimens should be avoided where practicable. The Cyclophorus has been delineated in the forthcoming final part of our joint work (pl. 144. f. 6), the Ampullaria in the preceding one (pl. 115. f. 2). I. CYCLOPHORUS OPHIS, Hani. T. depresso-turbiniformis, satis magna, late umbilicata, nitida, solidiuscula, leevigata, brunneo et albido concentrice undata vel nebulosa, ad basim albida, maculis parvis diversiformibus spiraliter fasciata ; spira satis elevata, apice livido. Anfractus valde convexi, 5|-6, superne paululum planiores, celeriter (ultimus prcesertim) accrescentes; sutura simplex. Apertura alba, permagna, unice hians, suborbicularis, latior quam alta, infra basim porrecta : labium acutum, late reflexum, undique expansum. Lat. circiter 2 poll. Hab. Tenasserim. Mus. Theobald. This remarkable-looking shell reminds one of C. tuba in shape, and C.siamensis in painting. Our specimen has an indistinct, interrupted, whitish peripheral fillet; and its surface exhibits, when magnified, some faint and close-set spiral wrinkles upon the upper portion of the final volution. 2. AMPULLARIA THEOBALDI, Haul. T. magna, solida, globosa, nitida, subleevigata, rugis incrementi umbilicum magnum versus subplicata; flavo-olivacea, antice (prcesertim) vittis brunneis, et plerumque angustis, ornata. Anfractus spiree vix elevatce, et seepius erosee, lati brevesque. Sutura profunda, in adultis subcanaliculata. Apertura elliptica ; faux chocolati colore tincta ; labium exterius albidum, seu flavescens,fusco-nigr•escente subarticulatum; labium interius atrofuscum. Long, et lat. 3\ poll. Hab. Bhamao, Birmah (Theobald). Mus. Hanley. This magnificent shell is named in honour of my coadjutor in our illustrated Indian conchology, wherein it has been delineated. It has the general aspect of A. zonata, is broad in proportion to the height, and has apparently no fillets near its profound suture. The calcareous opercle is heavy, and within of a livid smoke-colour. |
