ORDER BATRACHIA. 46/ 



goid, is united only by a ligament to the posterior point of 

 the maxillary, and presents a facet for the articulation of the 

 jaw. The lachrymal bone is very small, and placed at the 

 external angle of the anterior frontal. The bones of the nose 

 form a vault above the nasal fossae, which have no lower 

 cornets. 



The lower jaw, which is of a parabolical figure, exhibits a 

 true dentary bone, forming the symphysis with its congener, 

 and bearing teeth pretty nearly the same as in the majority 

 of the lizards. The remainder is composed in the adult 

 Salamanders of a single piece, which is double the length of 

 the preceding, at the lower half of the internal face, gives 

 out a coronoid crest behind, and bears the articular tubercle 

 which is intimately united to it by synostosis. 



Both jaws are armed with numerous and small teeth. 



There are fourteen vertebrae from the head to the sacrum, 

 and twenty-six to the tail, according to the Baron in the 

 Ossemens Fossiles ; about forty-two, according to MM. Carus 

 and Funk. The atlas is articulated to the head by two con- 

 cave faces, and with the axis by the lower face of its body, 

 concave also. But all the following vertebrae have the pos- 

 terior face of their body convex. 



The articular processes of the dorsal vertebras are hori- 

 zontal, and united on each side by a crest, like a rectangular 

 roof with the lateral edges a little re-entering. Their spinous 

 processes are nothing but a simple ridge. The transverse 

 processes have at their summit two tubercles, which carry 

 the vestiges of ribs. 



In the attachment of the pelvis to the spine, there are 

 numerous individual differences. Sometimes it is the fifteenth 

 vertebra, and sometimes the sixteenth, which supports this 

 part of the skeleton. 



In front of the symphysis of the pubis, is a cartilage formed
