G O D W I N - A U S T E N , F.R.S., F.Z.S., & c - P a r t I. [Eeceived March 23, 1888.] The following list comprises the shells which have reached me since our late occupation of the above country. The first batch were collected and sent me by m y former assistant in the Survey, Mr. M . Ogle, from the districts on the Kyeng-dwen, or Chindwen, east of Munipur. The second I have lately had placed in my hands by Mr. J. Ponsonby, who received them from Captain Spratt, R.A., from Upper Burmah, where that officer has been employed during the late military expeditions. The shells are not in a good state of preservation, and no doubt were collected under very considerable difficulties as regards leisure and deficiency of carriage. There are many new forms, showing what a rich harvest awaits the naturalists who could devote more time and care to the work. W e trust that Captain Spratt (son of Admiral Spratt, a life-long worker at the Mollusca) will yet be able to add still more to our knowledge of the species to be found in our newly acquired territory. I propose in this communication to describe the shells collected by Captain Spratt. Hlindet, where most of them were obtained, is situated on a tributary of the lrrawaddy, which, rising in the hills south of Mandalay, flows north to join that river at the sharp bend below that town. It is through this valley that the new line of railway is to run to the capital from Toungoo. The late Mr. Francis Fedden, of the Geological Survey, visited this part of Burmah and the Salwin valley, in 1864-65, and brought back with him a good many specimens of land-shells, which were described by Mr. W . Theobald in the Journal of the Asiatic Society for 1870. |
