J In the gallery the larger specimens are arranged either on stands or in table-cases, and the rest in the wall-cases.

Pterodactyles, as the members of this extinct order are called, flourished during the Mesozoic, or Secondary, epoch, and are dis- tinguished by the modification of the fore-limbs into wings, the
