There are about 17 species in Sang appreciable local 
mainland of Celebes, but which g^ the above list have in- 
differences. Of aese 17, no ewer than 12 n^med^r^^ 
creased in size in Sangi, while two , ^.g^^^i^-gg on the mainland.

Dicnirus leucops, Hermotimia sangnensis an Pplphesian allies,

In no case have Celebesian species decreased in size in Sano_ 1 
The imperfectly explored Talaut Islands are at .g* 
8 peculiar species allied to forms belonging to Cele e ^
