200 ACCOUNTS, ETC., OF THE BRITISH MUSEUM. 



The unexhibited Gastropoda belonging to the Gilbertson 

 collection of Carboniferous fossils, removed from Gallery 11, 

 have been re-labelled and incorporated with the General 

 Collection ; while the unexhibited Lamellibranchia from the 

 same collection have been re-labejled and are ready for 

 incorporation. 



Considerable progress has been made with the determi- 

 nation and re-arrangement of all the British Carboniferous 

 Gastropoda. 



The Mesozoic and Tertiary Gastropoda and Lamellibranchia 

 registered, labelled, and incorporated include : — Non-marine 

 shells from the Eocene, Oligocene, and Miocene of France 

 (Valabregue coll.), the Miocene of Germany (K. Fischer coll.), 

 the Post-Pliocene of Corsica and France (Caziot coll.), and the 

 Holocene of Newquay, CornAvall (B. B. WoodM^ard coll.) ; also 

 various Cretaceous shells. 



The arrangement of the European non-marine Tertiary 

 Mollusca has now been completed, and a slip-catalogue of the 

 collection has been made. 



The Pliocene Mollusca from Lenham, Kent, have been 

 determined and catalogued. 



Number of specimens of Mollusca registered : — Cephalopoda, 

 1,241; Gastropoda, 1,260 ; Lamellibranchia, 839. 



Arthropoda (Gallery 8 and Workroom). — The acquisitions 

 registered, labelled, and incorporated include : — Among Trilo- 

 bites, an important series from the Cambrian rocks of Comley, 

 Shropshire, including specimens described in the Quarterly 

 Journal of the Geological Society, 1910 (Cobbold coll.), a large 

 series from the Lower Carboniferous of Ireland, including 

 several originals of H. Woodward's Monograph (Joseph 

 Wright coll.), a large number from the Lower Palaeozoic rocks 

 of France, especially Herault (Valabregue and Escot colls.), 

 and fine specimens from the Devonian of the Eifel ; also 

 plaster casts of specimens described by Richter, 1912 ; among 

 Insecta and Arachnida, a number in nodules from the Coal 

 Measures of Staffordshire (H. Johnson and other colls.) ; among 

 Ostracoda, carefully-determined sets from the Palaeozoic rocks 

 of the United States CBassler coll.), the Lower Carboniferous 

 of Ireland (Joseph Wright coll.), and the Pliocene of Moravia 

 (Dabell coll.) ; among Cirripedia, important series from the 

 Chalk Marl of Cambridgeshire (Mockler coll.), the Senonian 

 of Riigen (Laur coll.), the Bryozoa Limestone of Faxe 

 (Mineralog. Mus., Copenhagen), the Miocene of Burma (Dalton 

 coll.), and the Pleistocene of Antrim (Donaldson coll.). 



Many of the old collections of Cirripedia have been worked 

 through, determined, and re-registered, e.g., from the Neo- 

 comian of Germany (Darwin, Damon, A. Krantz colls.), the 

 Danian of Belgium (Van Breda coll.), the Maestrichtian of 

 Maestricht (Bosquet coll.), and the Miocene of New Zealand
