One hundred nnd nine species of Echinoderms, chiefly from the Oolitic and Cretaceous

A series to illustrate the structure of the Crinoidea, chiefly from the Carboniferous lime- 

 stone of Clitheroe, has been mounted upon tablets, named and registered. 



Upwards of 1,400 MvUvsca have been identified and registere,d, and a considerable portion 

 of them are mounted upon tablets for exhibition. 



Of the Inverlebrata exhibited during the past year may be noticed : 



A series of Middle Eocene Mcllusca, from Bracklesham and Heme Bay; Room VI., 

 Table-case 8. Some new Crustacea from the Lias of Lyme Regis, and the Solenhofen 

 hmestone; Room VL, Table-case 7. A fine example of Pteri/gotiis anglicus, almost entire, 

 exhibited in the Windovv-reces?, Room VI. A slab of Bituminous shale filled with Trilo- 

 bites, &c., from Lake Huron; top of Wall-cnse 4, Room VI. 



A series of Lihellida from Solenhofen; Room V., Table-case 18. A new series of 

 Models of Foraminifera, by Wenzel Erie of Prague; Room V., Half Table-case 15. 

 Mass of A^w???WtMZ/wa Icp.vigala, from the Middle Eocene, Bracklesham. Room V., Cyca- 

 dites Saxbyana, Brown, and C. megalophylla, Buckl., and other large plant-remains, on 

 the tops of the Wall-cases, Room L 



Owing to the limited space for the exhibition of objects in the Table-cases, the majority of 

 the recent acquisitions aie placed in drawers, and it is proposed, when sufficient drawers are 

 procured, fo arrange the extra collections, not exhibited to the public, in Cabinets beneath 

 the Table-case containing the rest of the series. This arrangement has been effected with 

 the Tertiary shells, and the Radiata, and will in time be carried out in each series.
