sacral rib is much like that of Enjops in which the structure 

 takes a very unusual form for a rib. The phalangeal formula 

 for the foot is 1, 2, 3, 4, 2. The complete number of digits in the 

 hand is not preserved. The carpus has nine possibly eleven 



The paper is well illustrated. There is a restoration of the 

 skeleton of Trematops milleri and an outline drawing of the 

 scapula of Eryops latus Case. The new genus Trematops is the 

 type of a new family Trematopsidae in which the form described 



The same writer (4) has redeseribed from more complete 



the Permian of Texas. The paper is based on several more or 

 less incomplete skeletons. These include several additional 

 features to our knowledge of the anatomy of the peculiar Diplo- 

 eaulhhe. Limbs have heretofore been unknown in the group 

 although their presence has been suspected from the presence of 

 pectoral girdles preserved with some specimens. Dr. Williston, 

 however, for the first time actually describes well-formed limb 

 bones for the group. The humerus is very remarkable in that 

 it has an epicondylar foramen, a character known in only one 

 other amphibian, Acheloma. The complete morphology of the 

 skull with the exception of some features of the palate are made 



The paper concludes with remarks concerning the relationship 

 of the group to which Dlplnralus belongs and associates the 



Permian forms in which he describes a new genus and species of 

 amphibia under the name Cacops aspidephorus. This form he
