batrachians's Usage Examples:

- Tailed batrachians, with the frontals distinct from the parietals and the palatines from the maxillary.

Cold-blooded animals, such as reptiles and batrachians, thrive best in an equable temperature, and, especially in the case of snakes, frequently can be induced to feed only when their temperature has been raised to a certain point.

The Reptilia include II species of the crocodile, alligator and lizard, including the savage jacare of the Amazon, several species of turtle, 4 species of batrachians, and 29 species of serpents, including the striped rattlesnake (Crotalus durissus), Lachesis mutus, and a rather rare species of Cophias.

The integument of tailed and tailless batrachians is remarkable for the great abundance of follicular glands, of which there may be two kinds, each having a special secretion, which is always more or less acrid and irritating, and affords a means of defence against the attacks of many carnivorous animals.

These facts militate strongly against the importance which was once attached to the dentition in the classification of the tailless batrachians.

The pelvic arch of some of the Stegocephalia contained a well ossified pubic element, whilst in all other batrachians only the ilium, or the ilium and the ischium are ossified.

It is in fact doubtful whether the so-called sternum of batrachians, in most cases a mere plate of cartilage, has been correctly identified as such.

f, P, This is particularly evident in the case of the Stegocephalians; and recent batrachians, tailed and tailless, show the mode of articulation of the vertebrae,whether amphicoelous, opisthocoelous or procoelous, to be of but secondary systematic importance in dealing with these lowly vertebrates.

- Tailed, lacertiform or serpentiform batrachians, with the temporal region of the skull roofed over by postorbital, squamosal, and supratemporal plates similar to the same bones in Crossopterygian fishes, and likewise with paired dermal bones (occipitals and post-temporals) behind the parietals and supratemporals.

A fairly complete bibliographical index to these cases and the most remarkable instances of parental care in tailless batrachians will be found in the interesting articles by Lilian V.
