PALAEOZOIC AIE-BEKATHING ANIMALS. 79 



There are in our follectioiis nnmcrous iiidetermiiiate luid imperfect tbot|irints which have 

 not been named or catalogued. They indicate the presence of land vertebrates from the 

 base of the Lower Carboniferous up to the summit of the Upper Ooal-forraation ; and it is 

 highly probable that several of thcui belong to creatures not otherwise known. It is hoped 

 that eventually means will l;)e found to publish these, as well as many characteristic bones 

 of batrachians in the above list, which have not been adequately figured.
