Amphibia (1878) |
 | | 9;The Urodela are Amphibia with elongated bodies and relatively short limbs, devoid of scales or pectoral plates, with numerous præ-caudal vertebræ, and with amphiclous, or opisthoclous, vertebral centra. |
 | | The pectoral arch in the Amphibia is distinguishable into a scapular, a coracoidal, and a præcoidal region, although the extent to which these parts of the primitive cartilaginous arch become separately ossified varies very much in the different members of the group. |
 | | On the other hand, it is the male Alytes obstetricans which twists the strings of eggs laid by the female round his hind-legs and, thus cross-gartered, retires into seclusion until the young are ready to be hatched, when he resorts to the water in which the tadpoles are to perform their further metamorphoses. |
