The so-called Leucisciis dorsalis, L. dumerili, and L. sicamis, with 
two supposed new species, L. cecconii and L. saiivagei, 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, Bivista Ital. Paleont. 
vol. ii. 1896, pp. 227-232, pi. v. figs. 1, 8). Two specimens of this 
nature in the Collection are numbered P. 5548-49.
