[Aun. Sci. Geol. vol. iv. art. no. 1, 1873, p. 199.] 
Syn. Tydeus, H. E. Sauvage {non Koch, 1842), Ann. Sci. Nat. [5] 
vol. xiv. art. no. 7, 1870, p. 23. 
An imperfectly known genus, with much-elongated head and 
trunk. Cleft of mouth very large, with a few large spaced teeth 
and small unciform teeth between. Pectoral fins not much 
enlarged ; pelvic fins small and remote; dorsal fin short-based, in 
hinder half of back but completely in advance of the extended anal 
fin ; caudal fin forked. Scales of moderate size, uniform, and not 
serrated at the hinder border ; lateral line conspicuous. 
This genus is not yet clearly distinguished from the existing 
pelagic genera, Paralepis and Sudis.

Type. Imperfect fish. 
The type species, attaining a length of about 0’5. Length of 
head with opercular apparatus contained about five times, maxi¬ 
mum depth of trunk about ten times in the total length of the fish. 
Vertebrae nearly 100 in number. Pectoral fins with 20 rays; 
pelvic fins with 14 rays, opposite the origin of the dorsal, which 
comprises about 12 rays and is completely within the hinder third 
of the back ; anal fin with at least 30 rays, extending close to the 
caudal. Scales of lateral line not enlarged. 
Form. Log. Epper Miocene : Licata, Sicily. i •

by Sauvage) as young of this species. Egerton Coll. 
The following species from the Upper Miocene of Licata have 
also been recognised on the evidence of imperfect fishes, but are not
