Note 268 — Chapter IX · THE ORDER UNGULATA (continued 4)

Many authors use Cuvier’s name, R. indicus, in preference to this, on the ground that there are more than one species with one horn, forgetting that the name substituted is equally inconvenient, as more than one species live in India. The fact of a specific name being applicable to several members of a genus is no objection to its restriction to the first to which it was applied; otherwise changes in old and well-received names would constantly have to be made in consequence of new discoveries.
