The Zoological Museum of Amsterdam recently received some interesting samples of minute landshells collected by Mrs. G. A. Tammes—Bolt in limestone hills in the southern peninsula of Celebes. Among a lot of shells from a hill along the main road from Makalé to Kalossi, at 700—800 m altitude, collected in September 1948, there were about a dozen specimens of a new species of Gyliotrachela (Gastropoda Pulmonata, Vertiginidae), a genus hitherto unknown in Celebes.
