 British marine Post-Pliocene Mollusca, which is now as nearly 

 as possible complete. 



Some newly discovered Jurassic Mollusca from Singapore 

 have been mounted and labelled for exhibition. 



The labelling of the Cornbrash Ammonites has been 

 revised, and additions have been made to the exhibited 

 Palaeozoic Pteropoda. 



Post-Pliocene Lamellibranchia and Gastropoda from 

 Barbadoes, South Africa, Southern France, and Armenia ; 

 Miocene Mollusca from Hungary ; Cretaceous Mollusca from 

 France, Syria, and Armenia ; Jurassic Lamellibranchia from 

 France ; Carboniferous Mollusca from Belgium ; and various 

 other recent acquisitions have been registered, labelled, and 

 incorporated in the unexhibited collection. 



The unexhibited Wealden Lamellibranchia and Gastropoda, 

 and collections from the Italian Pliocene and the West Indian 

 Tertiaries, have been partly re-arranged to save space.

 363 ; Gastropoda, 1,405 ; Lamellibranchia, 2,218. 



Arthropoda (Gallery 8). — The registration, labelling, and 

 arrangement of the unexhibited Phyllocarida, Ostracoda, 

 ^irripedia, Phyllopoda, and Amphipoda have been completed, 

 and progress has been made with the unexhibited Decapoda. 

 The Cirripedia have been transferred to the drawers of a 

 new cabinet, leaving additional space for the other groups. 



Some of the trilobites have been provisionally sorted into 

 genera, in preparation for cataloguing.

 China, with numerous trilobites, has been mounted in a glazed 

 frame on the wall between wall-cases 14 and 15. 



Number of specimens of Arthropoda registered, 184. 



Vermes (Gallery 8). — All the unexhibited specimens have 

 been transferred to a new cabinet, thus leaving additional

 fitted round the workroom behind the Departmental Library,
