Brachiopoda (Gallery 8). — The arrangement, registration, 

 and labelling of the unexhibited Brachiopoda have been con- 

 tinued. Progress has chiefly been made with the Devonian, 

 Carboniferous, and Triassic specimens, and special attention 

 has been paid to those from Australia and to the Klipstein 

 Collection from the Alpine Trias. 



Several exhibited specimens from the British Carboni- 

 ferous have been re-labelled, and some additions have been 

 made to the series, especially among Strophomenidse. 



Number of specimens of Brachiopoda registered, 2,547. 



Echinoderma (Gallery 8). — All the unexhibited Cystidea 

 and Blastoidea have been transferred to new cabinets. It 

 has thus been possible to re-arrange the unexhibited British 

 Crinoidea and to incorporate many recent accessions. 



Various genera of Echinoidea, mostly Mesozoic, have been 

 revised, and the exhibited specimens re-mounted with printed 

 labels, e.g., Hemipedina, Diademopsis, Orthopsis, and 

 JEodiadema. 



A selection of Lower Devonian Ophiuroids from Bunden- 

 bach has been mounted in centre-case A 3, with explanatory 

 diagrams and labels. A few other additions have been made 

 to the exhibited series of Echinoderma. 



Number of specimens of Echinoderma registered, 4,251. 



Anthozoa {GsiWery 10). — The collection of Jurassic Corals, 

 from the Corallian, Great Oolite and Inferior Oolite forma- 

 tions, has been arranged, labelled, and completely registered 

 while incorporating recent acquisitions from the Tomes 

 Collection. 



A typical collection of British Jurassic Corals has been 

 arranged, tableted, and labelled, with explanatory diagiams, 

 in table-cases 2 and 3. 



Number of specimens of Anthozoa registered, 2,795. 



Hydrozoa, Porifera, and Protozoa (Gallery 10). — The 

 exhibited series of fossil Protozoa in table-cases 15 and 16 

 has been extended, revised, and partly re-labelled, with 

 explanatory diagrams. 



Number of specimens registered, 203. 



Plantce (Gallery 10). — The arrangement and labelling of 

 the Lower Eocene plants in table-case 18 have been com- 

 pleted. 



A portion of fossil tree, obtained by the Jackson-Harms- 

 worth Expedition in Franz Josef Land, has been mounted 

 for exhibition in wall-case 10. 



The arrangement, mounting, and labelling of the Rhajtic 

 and Triassic plant-remains in wall-case 14 have been 

 completed.
