both for this and the remainder o£ the same collection, which has 

 been arranged in drawers. 



Progress has also been made in the arrangement o£ drawers o£ 

 French and Italian Tertiary Mollnsca in the cabinets in the Work- 

 room. 



Cretaceous and Tertiary Mollusca from Angola and British East 

 Africa have been examined for determination and cataloguing ; and 

 Pliocene Mollusca from Lenham (Kent) and the bed of the North 

 Sea, have also been determined and catalogued. 



Number of Mollusca registered : — Cephalopoda, 683 ; Gastro- 

 poda, 376 ; Lamellibranchia, 360. Total, 1,419. 



Artliropoda (Gallery 8 and Workroom). — The acquisitions 

 registered, labelled, and incorporated include : — Ordovician Ostra- 

 coda and Trilobita from Wales and Shropshire (T. Ruddy coll.) ; 

 Silurian and Devonian Trilobita from Britain and Germany 

 (Champernowne coll.) ; Cirripedia from the Cretaceous of Bohemia 

 (Fritsch coll.), Denmark (Br. Nielsen coll. and Copenhagen Univer- 

 sity), and England, and from the Miocene of Italy ; Oligocene 

 Insecta from the Isle of Wight (A'Court Smith coll.) ; and Crustacea 

 from the Red Crag (A. Bell and A. S. Kennard colls.) 



The revision of the old collection of Cirripedia has been continued, 

 and several Cretaceous and Tertiary specimens have been mounted 

 for exhibition. Thin sections of various fossil Arthropod shells have 

 been cut to determine the affinities of some Palaeozoic fossils referred 

 to Cirripedes. 



Among other additions to the exhibited collection are a repro- 

 duction of Arthropleura moyseyi and several Cambrian trilobites. 



The mounting of the collection of amber inclusa has been 

 completed, as also has that of the gum-copal inclusa, except some

The slip-catalogue of exhibited specimens has been continued. 



Number of specimens of Arthropoda registered, 2,269. 



Echinoderma (Gallery 8). — The acquisitions registered, labelled, 

 and incorporated, include : — Ordovician Cystidea, Crinoidea, and 

 Asteroidea from Wales (T. Ruddy coll.) ; squeezes of Devonian 

 Crinoidea from Germany (made by W. E. Schmidt) and of Asteroidea 

 (made by F. Schoendorf) ; Blastoidea from the Carboniferous of 

 Valcour Id. (Hudson coll.) and of Missouri (Greger coll.) ; Lias 

 Crinoidea from the West of England (L. Richardson coll.) ; Jurassic 

 Echinoidea and Crinoidea from Cutch ; and Cretaceous Echinoidea 

 and Crinoidea from Bohemia (A. Fritsch coll.) 



An incomplete set of the plaster casts of Echinoids made by L. 

 Agassiz (presented by the Geological Society) has been checked by 

 his " Catalogus Ectyporum " and labelled accordingly. 



New Edrioasteroidea have been mounted for exhibition with 

 enlarged drawings. A group of the Liassic crinoid, JPentaonnus, 

 attached to a piece of wood, has also been exhibited. 



The slip-catalogue of exhibited specimens has been continued, 

 and that of specimens of Blastoidea has been brought up to date.
