Show 196 MR. E. R. SYKES OX [ Mar. 3, brunnea, strigis corneis picta, fascia unica nigro-brunnea ad peripheriam ornata; anfr. 44, mediocriter crescentes, convexi, sutura bene notata separati; apertura subcircularis, peri-stomate indistincte duplicator ala parva antice angulato. Alt. 8 ; diam. max. 16 millim. Hab. Gunong Inas, at 5000 feet. I thought at first that this might be a form of P. blandi Bens., but it appeals to be smaller, more elevate and not so widely umbilicated, and to differ in colour. In the two specimens that I have seen the lip is duplicated only on its outer margin, and the wing is small and thin. R hiostoma jalorensis, sp. nov. (Plate XX. figs. 6- 8.) Nearly related to R. housei but larger, slightly more depressed, and with the whorls not so tightly coiled. The tube is long and large, reaching the body of the shell, and is bent slightly backwards at the junction. The disjoined portion of the last whorl is much longer than is the case in P. hoitsei, as will be seen from the figure, and is more descending. The colour resembles that of P. housei, and a dark band is usually present at the periphery. Operculum as usual. Diam. max. 29 millim. Hab. Limestone Hills and Caves, Biserat, Jalor. I have been in some doubt as to whether this is not a local race of R. housei, but the differences are constant in the specimens examined and, I think, are of specific value. The porcellaneous appearance of the operculum, so often seen in this group, appears to be due to the wearing down of the outer layers. R hiostoma, sp. Hab. Kwala Aring, Kelantan. A single specimen which agrees well with R. jousseaumei De Morgan, save that the tube is placed a little further back from the mouth, and is thinner and more cylindrical. It appears safer, however, to await further material ere describing this form. OPISTHOrORUS PEXAXGEXSIS Stol. Opisthoporus penangensis Stoliczka, J. As. Soc. Bengal, vol. xlii. pt. 2, p. 265, pi. x. fig. 7. Hab. Kwala Aring, Kelantan. A single specimen, which I refer to this species with some doubt. R haphaulus ascexdexs, sp. nov. (Plate XX. figs. 11, 12.) Testa pupoidea, anguste umbilicata, fusco-purpurea, dense costu-lato- striata, spira bene elevata, apice obtusulo ; anfr. 6, plano-convexi, pemdtimus gibbosus ; apertura subcircularis, intus pallide fusca ; peristoma pallicle corneum, expansum et reflexum, marginibus callo juuctis; tubulus brevis, incrassatus, a sutura oblique ascendens. Alt. 18 5; diam. max. 9*5 millim. Hab. Patalung. |
