several recent forms, introduced for comparison with the 

 fossil ones. To these have been added some enlarged figures 

 of the animal and its shell. 



The unmounted specimens are arranged in sixteen drawers 

 beneath the table-case, 



Mollusca. — {d.) Gastero'poda and, Lamellihranchiata. 

 (Gallery No. -8.) 



Two hundred and eleven Mollusca from the Gault of 

 Folkestone, have been named, mounted on tablets, and 

 arranged in Table-case No. 98. Eight hundred and twenty- 

 seven Inferior Oolite Gasteropoda have been named. 



All the drawers containing Silurian Mollusca have been 

 critically examined, and 1,445 specimens named ; each .species 

 being placed in a separate tray, labelled and arranged in 

 drawers beneath the Table-case (89). 



A fine series of British Post-Pliocene Land and Fresh-water 

 Mollusca from special localities, have been carefully named 

 and mounted in glass-topped boxes, and arranged in a new 

 table-case in the centre of Gallery No. 8. 



They comprise 2,672 Gasteropoda, and 

 486 Lamellihranchiata. 



Total 3,158 specimens. 



A considerable number of the above specimens have had 

 their written labels replaced by neatly printed labels, and the 

 more minute shells have enlarged drawings placed beside 

 them. 



The Eocene Gastero'poda, from the Paris Basin, are at 

 present under arrangement. 4,272 specimens have been 

 named, mounted and arranged in Wall-case No. 4. The labels 

 for the larger specimens on stands and for those in boxes are 

 being printed. 81 large specimens of Tertiary Mollusca have 

 been mounted on painted stands for Wall-cases 3 and 4. 



The Mollusca registered during the past year number — 

 Gasteropoda 4,026, and Lamellihranchiata, 1,625. 



Molluscoida. — {Brachioiooda and Polyzoa). 



The Foreign Brachiopoda are under arrangement. 263 

 Silurian specimens have been named, labelled, and arranged ; 

 about 7,000 specimens have been examined and assorted, and 

 980 have been registered. They will shortly be placed 

 in Wall-cases 10 and 11, now being fitted up for their 

 reception. 



The British Post-Pliocene and Pliocene Polyzoa are at 

 present under arrangement : about 45 specimens have been 

 mounted and named; enlarged drawings (after Busk and 

 others) of their microscopic structure have been added to the 



0.81. series
