As Smith, in his report on the "Alert" Mollusca, pointed out, this species was described 

 and figured by Gray in 1845, and, therefore, Gray's name has priority over Dunker's serrulata. 

 The spécimens from the "Siboga" collection, which I refer to this species are ail young shells, 

 but they show the characteristic form of the auricles of P . lata^ and agrée in gênerai with this 

 species. Probably Reeve's Avicula reticulata (loc. cit., pi. XVIII, fig. 71) from Australia is 

 also to be referred to this species. 



Distribution : — P . lata is known from the Torres Straits, Port Essington, Moluccos and 

 the Gulf of Siam. 



In the "Siboga" collection there are three young shells collected from the Pearl Banks 

 near the Anchorage off Pulu Jedan, East coast of Aru Islands (St. 273).

As the synonymy given above shows, the Chemnitzian species crocea was described by 

 Leach under the name Avicztla chinensis. It is quite distinct from the species figured and 

 described by Reeve under this name in Conch. Icon. (pi. XV, fig. 57), but of his species
