 Flower' gives a figure wliicli justifies these 

 statements, but neither the one nor the 

 other agrees with my specimens. In the 

 manus of a Hifrar cuprxfiis (from ^'erreaux 

 ^i Paris) I find the following condition of the 

 carpus. The bones of the two series are 

 articulated consecutively, and not alter- 

 nately; they do not interlock, but inas-
