Appendix O] SPECIMENS OF ROCK AND SAND 1079
III. NOTES ON THE SHELLS BY D. W. F. BADEN-POWELL, M.A., B.Sc.
Maral-bâshi. Found in dune three miles E. of
Four specimens of a Limnaea which is intermediate to
L. auricularia, Lin., and L. peregra, Muller, var. inlermedia, Ferrusac in Lamarck, and one specimen intermediate to
L. palustris, Muller, and L. slagnalis, Lin.
Lop Desert. C. xciii (02-09).
Specimens of Limnaea also intermediate to L. auricularia and L. peregra.
Lop Desert. Lou-lan, below L.D. ruin, 5 ft. (031).
Three specimens which belong to the L. palustris—stagnalis series, and one with an incomplete spire which may be definitely referred to L. auricularia, Lin.
Kuchâ. In sand from Yardang, three miles SW. of C. cclxi a. A broken shell of L. auricularia, Lin.
Konche.darya, C. ccxlix, two miles SE.
Planorbis albus, Muller, and Limnaea, of the same intermediate group as S. 1. The Planorbis is represented by a rich collection of shells all belonging to the same species. They resemble P. issik-kulensis, Clessin, but present more numerous exposed whorls than that species. A comparison with Clessin's shells in the British Museum Collection confirms this identification.
Konche.darya, one mile north of (or). Three specimens of Limnaea auricularis, Lin. It may be observed that the spires are rather unusually elongated.
SistAn. Desert site S. of Sistan oasis.
Three shells belonging to the L. auricularia peregra group. The mouth is as broad as in L. auricularia, and in one example the spire is longer than in the two others.
All the freshwater Gasteropods just enumerated inhabit still or slowly running water, and are still found living in and about Turkestan and Kansu.
Khotan (0195). Brought by Abbas from Khotan I Tati'.
A single shell too abraded for identification. It belongs to the family Mitridae, and possibly to the genus Latirus. S.9. Khotan, Badr (o133).
A much-worn shell evidently belonging to the genus Oliva, and probably to the sub-genus Carmione. The shell is not only worn, but appears to have been ground down over the lip and the opposite part of the body whorl as if for suspension.
Neither this nor the preceding shell appears to be a derived fossil. Both might have been picked up from a tropical beach and transported by human agency.
