Tyi^e. Nearly complete fishes. 
A species attaining a length of about OM, perhaps sometimes 
larger. Length of head with opercular apparatus somewhat 
exceeding the maximum depth of the trunk and equalling one 
quarter of the total length of the fish. Yertebrse approximately 45 
in number, about half abdominal, half caudal. Dorsal fin slightly 
deeper than long, with from 12 to 14 rays, and its origin less than 
twice as remote from the base of the caudal fin as from the occiput; 
pelvic fins arising opposite the anterior half of the dorsal, midway 
between the pectorals and the anal; the latter fin less elevated than 
the dorsal, with about 20 rays and extending close to the caudal. 
Yentral ridge-scales with very prominent backwardly-directed point, 
about 22 in number.

Specimens like the following are usually named Clupea ventricosa 
(after H. von Meyer, Palaeontogr. vol. ii. 1851, p. 93, pi. xiv. fig. 1), 
but their comparatively deepened form seems to be due to distortion 
^ Also recorded from the Upper Miocene of Croatia by D. G. Ivramberger, 
Beitr. Palaont. Oesterr.-Ungarns, vol. iii. (1883), p. 76 ; and doubtfully from 
the Lower Miocene of Chiavon, N. Italy, by F. Bassani, Atti E. Accad. Sci. 
Napoli, [2] vol. iii. no. 6 (1889), p. 38, pi. ii. fig. 5.
