Type. Imperfect fish; Paris Museum of Natural History. 
The type species, attaining a length of about 0*2. Length of 
head with opercular apparatus contained slightly more than three 
times, maximum depth of trunk about five times in total length to 
base of caudal fin. Posterior portion of dorsal fin with about 10 
articulated rays; anal fin directly opposed to latter, with 8 or 9 
articulated rays; caudal fin sharply rounded, about twice as long 
as deep. 
Form, ^ Loc. Upper Eocene : Monte Bolca, near Verona. 
P. 1968, P. 3947. Fine specimen, in counterpart. The head is 
much crushed, but the inferior spines of the preoperculum 
are well shown. There are clearly only 10 abdominal 
and 14 caudal vertebrae ; the former with very short and 
stout neural arches and with robust transverse processes 
overlapped by short and stout ribs. There are traces of 
the delicate pectorals, and all the other fins are well 
preserved. The caudal fin is supported by five expanded 
haemal arches, the uppermost the largest. The scales are 
seen and exhibit fine radiating markings in their covered 
portion, but their hinder margin is not clearly observable. 
The lateral line is conspicuous.
