[2] vol. iii. p. 489, pi. xx. fig. 1. 
Type. Imperfect disk, wanting snout and portion of tail; British 
Museum. 
Bounded upon an imperfect specimen related to B. tenuirostris, 
but apparently differing from this species in the proportions of the 
vertebra, which are relatively shorter, and also in the large size of 
the teeth. This example being a male, however, it is uncertain 
whether the differences in question may not be merely sexual. 
Form. Sf Loc. U. Cretaceous (Turonian): Sahel Alma, Mt. 
Lebanon, Syria.
