Plates viii. and ix. represent the perfect shells, casts of which are 

 figured in the other plates under corresponding numbers. 



Plate X. contains some illustrations of recent Foraminifera (see 

 pp. 188 and 202). Thus figs. 41 and 42 are young Botalia Beccarii, 

 of the feeble variety that lives in estuarine and sub-brackish waters. 

 Its shell is thin, and its chambers are not so compactly fitted together 

 as in the well-grown individuals inhabiting deeper sea-water. Mr. 

 Eley's drawings represent the pseudopodia freely exserted. Tig. 43
