I am using the Linnaean names for this and the preceding in 

 the sense in which they are employed in Britton's Manual; 

 whether this application will be fmal or whether we may have 

 more than these two fonns I cannot say. This group is one 

 which I ami personally unable to study at close quarters. Dr. 

 Mearns' paper (Pr. Biol. Soc., Wash, xv., 148, 1902) should be 

 studied in this connection.
