No. 294. Cheirotherium Barthi, Kaup. 



Track, on slab (relief)- Tliese 

 remarkable footmarks strikingly 

 resemble the impression of the 

 human hand, whence the generic 

 title. The tracks of the hind-foot 

 are about eight inches long and 

 five wide. Less than two inches 

 in advance of them are the prints 

 of the fore-feet, which are only 

 four inches long and three wide. 

 The foot-prints follow one another 

 in pairs, about fourteen inches 

 apart. Dr. Kaup, who first de- 

 scribed these ichnites, conjectur- 

 ed that the animal might have 

 been a large species of the Opos- 

 sum ; but in the didelphic quad- 

 rupeds the thumb is on the inner 

 side of the hind-foot. No certain 

 remains of the Cheirotherium 

 have been found ; but bones of 

 LabyrintJwdan have been found 

 in the same locality as the foot- 

 prints ; and it is highly probable 

 that the Cheirotherian tracks are 

 those of Labyrinthodoht Reptiles. 

 This specimen, discovered in the 

 New Red Sandstone (Lower Trias) at Jena, Gel-many, belongs to the Ward Mu- 

 seum in the University of Rochester. Size, 6 ft. 2 in. x 18 in. Price, $10.00.
