At Palermo there have been found 279 species fossil, the names 

 of which there is not here space to record, but they will be seen in

 statement of the result : —

At Messina 166 species have been collected, chiefly by M. Otto 

 (Enum. vol. ii. pp. 259, 260). The following is the result : —

Near Militello, as well in the basaltic tufa as in the Cava di Fos- 

 chega, Cava de' Monaci, between Militello and Palagonia, there are 

 132 species, whence we obtain the following table. (See Enumer. 

 vol.ii. pp.260, 261.)

Near Sciacca65 species have been found (Enumer. vol. ii. p. 261), 

 of which 7 (11 per cent.) are not now in the Mediterranean, and 4 

 (6 per cent.) are extinct. 



From Cefali close to Catania we have 109 species (/. c. p. 262), of 

 which 43 are Conchifera and %Qi Gasteropoda. Three of the former 

 (9 per cent.), and six of the latter, also 9 per cent., are absent in the 

 neighbouring seas, while two of the former and all the latter six are 

 extinct: we have therefore 9 per cent, locally and 8 per cent, abso- 

 lutely extinct.
