A fine example o£ Plesioteuthis prisca from the Lithographic 

 Stone, Bavaria (described by Gr. C. Crick in Proc. Malac. Soc, 

 1915), has been framed and added to Wall-case 7. 



A small glass case has been fitted between Wall-cases 10 and 

 11 for the exhibition of two fine British Inferior Oolite Ammonites. 



One section of Wall-case 11 containing Liassic Ammonites has 

 been cleaned, and all the specimens have been re-arranged and 

 relabelled. 



A slab of Lower Lias Limestone with Ammonites has been 

 mounted on a block and placed on the top of Wall-case 12. 



The Ordovician Nautiloids in Wall-case 14 have been re- 

 ^arranged, and representatives of four additional genera added. 



Further progress has been made with the revision of the whole 

 of the Museum collection of British Lias Ammonites, and with the 

 labelling of the selection prepared for exhibition. 



The slip-catalogue of type, figured, and historical specimens of 

 Cephalopoda has been continued. 



Palseozoic Gastropoda and Lamellibranchia registered, labelled, 

 and mostly incorporated include : — Ordovician Gastropoda and 

 Lamellibranchia from North Wales (T. Ruddy coll.) ; Silurian 

 Lamellibranchia from Scotland (W. McPherson coll.) ; Devonian 

 Gastropoda and Lamellibranchia from the Eifel, Germany (S. 

 Dohm coll.) ; Gastropoda and Lamellibranchia from the Car- 

 boniferous Limestone of Derbyshire (F. A. Bather coll.) ; Car- 

 boniferous Gastropoda and Lamellibranchia from Scotland (J. 

 Bennie and R. Dunlop colls.) ; Gastropoda and Lamellibranchia 

 from the Lower Carboniferous of Missouri, U.S.A. (D. K. Greger 

 coll.) ; and Permian Gastropoda and Lamellibranchia from the 

 Malay Peninsula (J. B. Scrivenor coll.). 



The unexhibited specimens of Foreign Palseozoic Gastropoda 

 and Lamellibranchia have been transferred from Gallery 8 to 

 drawers in a new cabinet in the back corridor, and the British 

 Oarboniferous Gastropoda and Lamellibranchia have been trans- 

 feried from drawers in the Workroom to drawers beneath the 

 upright cases A 6 and A 7 in Gallery 8. 



Progress has been made in the identification and relabellino- 

 of the Klipstein collection of Triassic Mollusca from St. Cassian in 

 the Tyrol. 



The slip-catalogues of type, figured, and historical specimens of 

 Palreozoic Lamellibranchia and Gastropoda have been continued. 

 Slip-catalogues of the exhibited collections have also been prepared. 



The Mesozoic and Tertiary Gastropoda and Lamellibranchia 

 registered, labelled, and incorporated, include : — Upper Ch-etaceous 

 (Danian) Mollusca from Denmark (Pindborg coll.) ; and British 

 Lower Cretaceous shells (Aptian) from Great (/hart near Ashford, 

 collected by Prof. J. W. Gregory and noticed by him in the Geol. 

 Mag. 1895. 



A series of Tertiary non-marine Mollusca from European con- 

 tinental localities has been arranged for exhibition in an upright 

 <case in the centre of Gallery 8. A slip-catalogue has been prepared
