The so-called Leuciscus dorsalis, L. damerili, and L. sicctnus, with 
two supposed new species, L. eeeconii and L. sauvagei, are also 
described from an Upper Miocene Tripoli at Mondaino, Province of 
Forli, Italy ; but the original specimens appear to be as unsatis- 
factory as those from Licata (I. Bonomi, Itivista Ital. Paleont. 
vol. ii. 1896, pp. 227-232, pi. v. figs. 1 , 8). Two specimens of this 
nature in the Collection arc numbered P. 5548-49. 
By exchange, 1 888.
