in Tertiary times chiefly Reptilian and Placental. (Illustrated by a 

 Table.) 



In conclusion, the recent character of the early marine faunas of the 

 Cambrian and Lingula-flag series was pointed out, such as Spongida, 

 Annelida, Echinodermata, Crustacea, Polyzoa, Brachiopoda, Lamelli- 

 branchiata, Pteropoda, Nucleobranchiata, and Cephalopoda. This was long 

 ago insisted on by Professor Huxley ; and we find no evidence of its 

 having lived near the beginning of the zoological series ; for below the 

 Cambrian series we are at once involved in a sort of chaos of meta- 

 morphic strata. Of the geological history, in the words of Darwin, 

 " we possess the last volume alone, relating only to two or three countries." 

 The connexion of this question with that of the comparative value of 

 different geological eras is obvious, especially in relation to the palseonto- 

 logical part of the question.
