[2] vol. iii. p. 489, pi. xx. fig. 1. 
Type. Imperfect disk, wanting snout and portion of tail ; British 
Museum. 
Pounded upon an imperfect specimen related to R. tenuirostris, 
but apparently differing from this species in the proportions of the 
vertebra), which are relatively shorter, and also in the largo size of 
the tooth. This example being a male, however, it is uncertain 
whether the differences in question may not he merely sexual.
