In the specimen from the Gulf of Siam the ribs are not markedly granu- 

 lated. Prof. Ed. v. Martens, whom I asked to compare the specimen with Dunker's 

 original specimen, informed me that it "stimmt ganz gut zu den Original Exem- 

 plaren von A. mollis, Dunk."

According to E. v. Martens ^ this species occurs frequently in brackish water 

 at Singapore, on Borneo, Celebes, Sunda Islands and other places. M. v. Neumayer 

 states^ that an "Area granulosa L. var. minuta" was found among fresh-water shells 

 ("und zwar mit Arten der Gattungen Vivipara, Bythinia, Melania und Corbicula") 

 in the deposits of the Yang-tse-kiang delta. This is nearly certainly a form of 

 A. granosa which lives here in brackish water under conditions similar to those 

 prevailing in the localities' stated by v. Martens.
