The name Cybium tenue was proposed by Agassiz (Neues Jabrb. 
1835, p. 305) for an undescribed fish from the Uppor Eocene of 
Monte Bolca. An undetermined species has also been recorded 
from corresponding strata at Monte Postale (E. Bassani, Atti B. 
Accad. Sci. Napoli, ser. 2, vol. iii. 1889, no. 6, p. 77). 
Genus EOCCELOPOMA, novum. 
Syn. Coclopoma, L. Agassiz ( non Adams, 1867), Bep. Brit. Assoc. 
1844 (1845), p. 307 (name only). 
A genus known only by the head. Cranium rather short and 
broad ; fossae for lateral muscles of trunk extending forwards much 
beyond the hinder margin of the frontals to a point above the 
middle of the orbit; frontals nearly as broad as long, marked with 
rugosity laterally, sharply depressed mesially just in front of the 
posterior fossse, and the hinder part of their median suture at the 
anterior end of tho low supraoccipital ridge gaping to form a small 
vacuity. Teeth on margin of jaws rather large, stout, conical, and 
well-spaced, not much laterally compressed ; minute teeth on 
vomer.
