Bed-dome is a single shell from the Wynaad which appears to be a still larger form, measuring 8, 6, and 4 m m. STREPTAXIS SCALPTUS sp. nov. (Plate L. figs. 8, 9, 10.) Testa rimato-perforata, subumbilicata, depresso-ovata, costulato-striata, subtus Icevigata, cereo-albida ; spira depresso-conoidea, sutura impressa ; anfr. 5^-6, convexi, penultimus ad peripheriam rotundatus, paullo ultra ultimum projectus, ultimus excentricus, subtus convexus, versus aperturam circa umbilicum comprcssus, utrinque fossiculo impresso coarctatus; apertura obliqua, fere semiovalis, lamellis plerumque duobus parietalibus approximatis, sinistrali media longiore intrante, dextrali minore, aliquando carente, dentibusque ad quatuor (interdum 2, 3 vel 5) palatalibus constricta ; peristoma album, expansiuscidum, juxta angulum mediocriter sinuatum. Diam. max. 10, min. 7 ; alt. 5j| mm. Hab. in montibus Kolamalai dictis, haud procul ab urbe Salem India? meridionalis (Beddome), et in provincia Kadur, regni Indici Mysore (Daly). This, like some other South Indian Streptaxes, is a very variable species. Even amongst specimens from the Kolamalais some shells are much more depressed than others, the largest examined measuring 11|, 8g, and 5| m m . hi its three diameters, whilst the smallest measures 8§, 6^, and 4|. The single specimen from Balur, in the Kadur district of Mysore, measures 10, Ik, and 5\. Then the palatal teeth vary in almost every individual examined : tbe normal arrangement appears to be two in the right margin, one of them opposite the end of the median parietal lamella, the other nearer the angle, one basal or distal, and one columellar nearer to. the distal extremity of the aperture than to the proximal end. Some specimens (as in fig. 8) have two columellar teeth ; in one shell the basal and columellar teeth are wanting, but this is evidently abnormal. Even in the excentricity of the last whorl, shown by the extent to which the penultimate projects when viewed from below, there is some variation. This species is distinguished from most of the South Indian Streptaxes by its subcostulate striation. The species with similar sculpture are S. pronus, which is smaller and very differently shaped, and S. canaricus and S. subacutus, with the penultimate whorl keeled. A single specimen from Torna was obtained some 30 years ago by Col. Evezard and has been in m y possession ever since. It was noticed in"Contributions to Indian Malacology, No. xii." (J. A. S. B. xlix. pt. 2, 1880, p. 205), as coming from the most northern locality in Peninsular India from which a Streptaxis has been obtained. Torna is a Mahratta hill-fort, near Sinhgarh, south-west of Poona. The Torna shell is large (length 111, breadth 8|, height 6 mm.) and somewhat weathered, with the whorls slightly sub angulate below the suture and with traces of spiral sculpture on |
