Postscript 



The writer desires also to thank Dr. Burnett Smith for the privilege of ex- 

 amining the collections from Brewerton, Phoenix, and near Three Rivers Point. 

 These confii-m the deductions above made. The faunas, partly new, are being 

 studied for publication by one of Doctor Smith's students.
