* As already stated, this species is of such very doubtful value, that it cannot yet be seriously entertained as a 

 factor in the geographical distribution of the genus ClieVuJon. 



t This species ought to have appeared in our Table under the Sudanese column. 



+ Wcddenia, for the reasons stated (sujjrd, p. siii), may have to be restored to its position as a distinct genus, 

 in which case it will be a peculiar West-African form, Waldenia nigrita. 



§ May prove to be distinct from Pliedina. 



I! This species may be found to belong to the Cameronian Sub-Eegion only.
