AMPHIUMID^. 



Ethmoid bone present; vestibule osseous internally. No malar or 

 quadratoJLigal bones. Vertebrae ampbicoelous, with two anteriorly di- 

 rected hypapophyses at the anterior extremity. Scapular and pelvic 

 arches and limbs present. Vomerine teeth on anterior or external 

 border of vomer, which does not bound the choaujB posteriorly. No 

 parasphenoid teeth. Liver not finely divided. Cloaca without pro- 

 jectile muscles. Tail developed. No exteraal gills. There is but one 

 ceratobranchial bone, and but one basibranchial. There are three 

 epibranchials. Besides hypohyals there are basihyals. No otoglossal. 

 The stapes is directly connected with the quadrate by cartilage. 



By all authors the genus Amphiuma had been included in the same 

 family division with Protonopsis and Megalobatrachus until 18GG, At 

 that time the writer proposed to separate it from the latter genera as 

 the type of a family Ampbiumithe, while the other genera were placed 

 in another family with the name Protonopsidte. This course lias not 

 been followed by later writers; in the catalogue of the British Museum 

 bj^ Dr. Boulenger (1882), for instance, the three genera are included in 

 one family, the Amphiumid;Te, 



The reasons for keeping the AmphiumidiTe distinct from the Protonop- 

 sid?e were stated to be the following :* 



A]VipniUMiDyT3 : "An axial cranial bone (? vomer) in front of orbito- 

 spheuoids, and one forming palatal surface in front of parasphenoid.
