 ties; of others I have nothing particular to record, and so the name 

 alone appears. I have also added to many of the species informa-

 species separately, is much clearer and more useful, although taking 

 up more si)ace. The difficulty with statistics is, that they have to be 

 taken on trust, if the facts on which they are based do not appear 

 in the same paper; this is just what I want to avoid in the present
