Amphiuma

The fore-limb is a simple filament in _Lepidosiren_, and presents few joints in _Proteus_ and _Amphiuma_; in other air-breathing Vertebrates it shows

The special interest attaching to the two first is that they represent a type of Labyrinthodonts hitherto unknown, and corresponding with Siren and Amphiuma among living Amphibia.

Siren and Amphiuma are two water animals quite characteristic of this zone, and their bites, like those of hundreds of other and equally totally harmless creatures, are regarded as deadly poisonous.

In Cryptobranchus (as in all the Urodela yet enumerated except Amphiuma), though the young have gill-openings and external gills, the adults are devoid of both.

In the frog (and in all its class) we find but a single vertebra representing these two, but in some allied forms, e.g. in Amphiuma, this vertebra develops a median process, reminding us of the odontoid process of the axis.

In Amphiuma they are completely wanting, and in Proteus and in the Ophiomorpha the minute eyeballs are covered with the ordinary and unchanged skin of the head.

The greatest excess of this development, however, is found in the North American genus Amphiuma, the minute limbs of which have either three or two toes, according to the species.

In many tailed Batrachians the vertebræ are biconcave, as e.g. in Spelerpes, Amphiuma, Proteus, and Siren.
