R. paleindicus are—firstly, that the cranium in the British Museum indicates that 
the species to which it belonged was a one-horned form; and secondly, that the 
milk-molars are of too large a size to have belonged to A. stvalensis—the other one- 
horned form. The Dublin specimen shows that the structure of the milk-molars is 
rather more complex than that of the true molars of R. paleindicus.
