Memoirs of the Asiatic Society of Bengal. Zoological Results of a Tour in the Far East

In the Malay Peninsula apart from a few specimens collected on the islands of Singapore and Penang and at the mouth of the Prai River on the mainland immediately opposite the latter my attention was directed mainly to the Tale Sap or Inland Sea of Singgora which lies in the Siaese Province of Sunkla. [...] I also made small collections at the mouth of the Patani River which opens into the Gulf of Siam some distance south of the mouth of the Tale Sap and in the caves of Jalor in the same province. [...] They approached the Prefect of the Shiga Prefecture and the Corporation of the city of Otsu. [...] Studied the topography of the lake and the littoral fauna in the neighbourhood of Otsu. [...] The majority are from the Tale Sap in the north-eastern part of the Malay Peninsula but a few come from the Tai-Hu in the Kiangsu Province of China.
