the other. The one with the ovate outline has only small oblong 

 dark spots on the interambulacral spaces. The more oblong one has 

 the dark spots on the back of the interambulacral spaces large, trian- 

 gular, and confluent with the dark ambulacra on the sides of which 

 they are placed ; there are also two narrow dark bands on the middle 

 of the upper part of the side margin.

 Department, British Museum. 



I have been enabled, through the kindness of Mr. Salvin, to make 

 the following additions and corrections to my Monograph, read at 

 the Meeting of this Society held the 23rd of January in the present 

 year (see P. Z. S. 1866, p. 43).

This species has been considered a synonym of D. affinis, but 

 it is evidently very distinct ; it is much smaller, the submarginal 

 spots larger and more regular, the white patch in the front wings 

 bordered with reddish, the central band of hind wings occupying 

 nearly the entire wing.
