The newts lack the stylus to the columella, while Salamandra and Chioglossa retain it fused to the periotic. The newts are frequently separated from the other salamandrids as a distinct family, the Pleurode- lidae. Since these other genera were apparently derived from the primitive salamandrids, this arrangement has little in its favor.

. The biology of the amphibia. Amphibians. D.GI. In the cloaca of the female salamander all three sets of glands may appear, although here they have different functions. The pelvic gland serves as a res- ervoir for the spermatozoa which migrate from the dis- integrating spermatophore held between the lips of the cloaca to these tubules in the roof of the cloaca (Noble and Weber, 1929). The cloacal glands which are present in all ambystomids, salamandrids, and primitive plethodontids, may play some part in egg- capsule formation. The ab- dominal glands are also de- veloped in female newts.

Primitive salamandrids with long maxillae, such as Tylototriton, have palates which are essentially like those of frogs (Fig. 80). On the other hand, Ascaphus, some species of Scaphiopus, and various other Salientia may lack the quadratojugal and hence have a skull outline resembling that of the salamandrid, Pachytriton, closely.. A B Fig. 81.—Palates of a frog and a salamander with reduced maxillae. In most salamanders the maxillae fail to reach the quadrate and a quadratojugal is missing.
