 quently corrected to Aru Islands.

 Medijla inscul/Aa, Pfr., a Norfcjlk island shell. The Siani habitat is 

 ju-obably based on a change of labels. It is, however, a curious coinci- 

 dence that Professor von Martens mentions (Ost-Asien, p. 74) that he 

 found in Moussons collection a shell which the latter received from 

 Bernardi with the habitat Siam. This shell Professor von Martens 

 identifies as ; Truchumorph'i insculjifa, Pfr.
