138 THE COAL MEASURES AMPHIBIA OF NORTH AMERICA. 



An additional specimen (No. 8683 G, of the Newberry Collection, American 

 Museum of Natural History) reveals no new facts as to structure, but serves to 

 show that the body of the animal was long and slender (plate 21, fig. 4). The por- 

 tion studied comes undoubtedly from the middle of the body. No limb elements 

 are preserved. The scales are somewhat larger, especially toward the sides of the 

 body, than in the type. The fragment measures 70 mm. in length by 18 mm. and 

 26 mm. in width. One of the largest scales measures i mm. in diameter.
