 The species should l>e known as A\ rassiveldti iinx (Pennant)

 dried specimen of this species with the inscription '' Knri/dlc

 that the first of these species, ddarti/la, is the type of Hippa 1787 ; 

 and that decision is not altered in the light of earlier hut similar 

 removals of the various othei- species l)y \\'el)er in 17^15. The 

 second species of Itlofen, enwrifd, is therefore its type, hut this 

 species has l)ecn reckone(l the type of Kiiwritd (irono^'ius 

 1764 (not 176H) by Benedict.* and if this action l)e sustained, 

 Idotca ^^'el)er becomes a synonym of Einerita; it is obvious that in 

 any event Idotea is not availal)le for a genus of Isopods as defined 

 l)y Fahricius 17^)8. The inclusion of ddactjiUi and emeritus in 

 Idotea is referred to l)y Roux under Idotea in " Crustaces de la 

 Mediterranee,'^ 1828, but is there attributed to Daldorf.
