110 The Zoologist — February, 1866. 



new genus and under a new name ; but in his opinion there was not any subordinate 

 or intermediate stage between the species and the genus to which it was either neces- 

 sary or desirable that a distinct name should be ap|)lied. 



Mr. Stainton thought that, in the state at which Natural History had arrived, and 

 owing to the immense variety of forms which had been and would doubtless continue 

 to be discovered, there was only a choice of diflBculties from which he saw no escape : 

 on the one hand, if comparatively small differences were for generic purposes dis- 

 regarded, the genera became unmanageable in extent and incapable of precise descrip- 

 tion ; on the other hand, if such differences were taken into account, there was no 

 limit to the creation of genera ; almost every species would eventually be raised to 

 generic rank, or rather the genus would sink to the level of the species, and in fact be 

 lost as a distinct step in the ladder of classification.
