(J. Wright Coll.), the Coal Measures of Derbyshire (L. Moysey 

 Coll.) and Gloucestershire (H. Bolton Coll.), the Lias of 

 England (Brodie, Buckman, Harford Colls.), the Bathonian of 

 Northamptonshire (Jesson Coll.), the Wealden of Hastings 

 (Teilhard and Pelletier Coll.), the Cretaceous of Hanover 

 (Schrammen Coll.), and the Oligocene of the Isle of Wight 

 (A'Court Smith Coll.). 



The unexhibited Arachnida and Merostomata have been 

 removed to the new cabinets in the Workroom. The specimens 

 of Parka decipiens have been examined and transferred to 

 the fossil plants. 



Several hundred specimens of insects in amber have been 

 trimmed and polished, and they are being placed for better 

 preservation in glass cells in a specially prepared resin. 



Among additions to the exhibited collection are remains of 

 the Cirripede, Brachylepas naissanti, and an electrotype 

 of the type-specimen of the Silurian scorpion, Falceophonus 

 caledonicus. One of the specimens of Paradoxides davidis 

 has been cleaned and identified as the type. 



The slip-catalogue of exhibited specimens has been con- 

 tinued. 



Number of specimens of Arthropoda registered, 2,384.
