On account of several of the figures of Foramiuifera by Fortis 

 being the first published in illustration of the species, we have 

 included in the above list those of Orbitoides, Alveolina, Fabu- 

 laria, Orbitolina, and Calcarina, completing (with some indeter- 

 minable objects) the list of Fortis's Discolithi. To his figures of 

 Alveolina and Fabularia we have made frequent allusion in the 

 Ann. Nat. Hist. ser. 3. vol. viii. p. 162.
