Dr. Bastelberger reeognizes three eleinents: (1) species peculiar 

 to h'oi'inosa, either very distinct from all othei's known and perhaps 

 ivpresent ing an indigenoiis fanna,. or clost^ly ailied to others yet suffi- 

 cieiitly differeutiated by long geogra])hical Isolation; (2) forms belonging 

 to the Jai)anese fauna; (3) those which are not met with again until
