304 Mr. R. I. Pocock on the 



scorpius and, e. g., Scorpio, and the wide difference between 

 Eusco?pius 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.
