STRUCTURE AND DEVELOPMENT OF LEPIDOSTEUS. 97 



The last section of the paper is devoted to the consirlera- 

 tion of the systematic position of Lepidosteus. The 

 Teleostean affinities of Lepidosteus are brought into promi- 

 nence, but it is shown that Lepidosteus is nevertheless a true 

 Ganoid. 



The arguments used in this portion of the paper do not 

 admit of being summarised.
