Type. Noarly complete fish. 
A small species, attaining a longth of about 0 - 12, the caudal 
region comparatively stout and slightly longer than the abdominal 
region. Dorsal region not much elevated. Length of head with 
opercular apparatus nearly equalling the maximum depth of the 
abdominal region, which is contained about two and a half times in 
the total length of the fish to the base of the caudal fin. Abdominal 
rcrtebrae 16, caudals 18 in number. Each pectoral fin with about 
id rays, the longest not reaching the pelvic pair, which arises 
nearly midway between the pectorals and the anal, opposite the 
origin of the dorsal ; dorsal fin longer than deep, with 17 rays, 
occupying nearly the middle third of the back ; anal fin much 
extended, with 29 rays, arising in advance of the hinder end of the 
dorsal. Dorsal scutes about twice as broad as long, with a longi- 
tudinal median keel ; ventral ridge-scales about 25 in number, not 
serrated, decreasing in size backwards. 
The fossilised examples of this fish are very variously distorted, 
a nd it is thus difficult to determine its precise form and proportions. 
The so-called Clupea larteti, Sauvage, from Hakel, Mt. Lebanon, is 
piobably a specimen elongated by distortion. It is stated by 
Sauvage to have 38 vertebne, but only 33 are shown in his figure 
of the type specimen.
