304. Mr. R. I. Pocock on the 
scorpius and, e. g., Scorpio, and the wide difference between 
Euscorpius and the Ischnurine group. 
It is not my intention on the present occasion to enter upon 
any criticism of the classifications proposed by the authors 
mentioned above. I will merely represent these classifications 
in tabular form, so that a glance will suffice to show how the 
new grouping of the genera agrees with or differs from those 
that have been published before.
