The génotype, by monotypy, is Lncina edentula (Linn.). I cannot agrée with Stewart's suggestion 

 that Lîicina s. s. equals Hère Gabb.

In view of Hanley's observations on the shells of this species in the Linnaean Cabinet, 

 there can be little doubt that the Linnaean species was from the Indo-Pacific Région. The species 

 was described and figured by Reeve under the names ovum^ philippiana and pila ; his edentula^ 

 as Dall ^) rightly inferred, is L. chrysostoma PhiUppi. 



The species is well figured by von Martens in his account of the fresh and brackish 

 water moHuscs of the Dutch East Indies. 



Distribution : L. edentula has a wide range in the Indo-Pacific. 



In the "Siboga" collection there are only young shells of the species from near the 

 reef of Batjulmati, Java (St. 7), Pulu Kaniungan Ketjil (St. 89) and Anchorage off Beo, 

 Karakelang Islands (St. 131).
