82 FIN-RAYS IN CLASSIFICATION OF FISHES. 



It will be noticed that the results arrived at iu re^spect to the 

 taxonoraic value of the characteristics of the development of the rays 

 of fishes of the different groups are essentially *in isccord with the 

 views of the best American authorities on the subject. The results here 

 given re-enforce, it seems to the writer, in a remarkable way the views 

 of Gill and Cope as to the systematic relations of the larger groups, 

 and serve at the same time to indicate that the group Pahieichthyes of 

 Giinther must be looked upon as a thoroughly unnatural assemblage 

 of forms.
