]S'o otber land mollusc has so wide a geographic range as 

 Eidota similaris. It is probably indigenous in Central and 

 Southern China, Burma, Cochin Chiua, Siam, the Malay 

 Peninsula and Singapore, Java, Celebes, Timor, and the Phihp- 

 pine Islands, but, " by the unconscious intervention of commerce 

 it has become colonized," as Prof. Pilsbry remarks, in Japan, 

 Formosa, Hongkong; Bengal; Ascension, Eodriguez, Keunion 

 (Bourbon), -Alauritius, the Seychelles, the Comoros, Madagascar, 

 and Natal ; New Soutli Wales; the Sandwich Islands; Bermuda, 

 Cuba, and ]3arbados ; Brazil and Argentina. Deshayes was, 

 1 bel'ieve, the first to draw attention to its wide distribution 

 when he questioned if there was another instance of a terrestrial 

 mollusc occurring in so many remote habitats, adding that it 

 would be of great interest to examine the animals from the 

 various localities, so as to make sure that they belouged_ to the 

 same species. It has long been considered that it owed its wide
