Diagnosis. Standing near the typical C. frenatus, hut smaller, and browner (less yellow) 
oHvaceous above. 
Measurements (adults). Wing 49 — 56 mm; tail 31 — 39; bill from feathers of forehead 17 — 
18; tarsus 12.5 — 14. 
Distribution. North, West, East and South-east Celebes: Minahassa (Forsten gl, Wall.

The birds of the lowlands of South Celebes are represented by the formula:

Diagnosis. Like G. frenatus saleyerensis, but the olive of the upper parts with a slightly 
gi-eener tinge, the under parts deep yellow, almost as in the typical form. 
Distribution. Lowlands of South Celebes: Macassar (Wallace ll. Platen pi, Weber q2 
P. &E. Sarasin), Batubassi (Meyer y 5), Kalibangkere (Platen pi). 
We have next to do with the bii-ds from the Peak of Bonthain and the high- 
lands around it, wliich have been named by iVIr. Hartert G. frenata dissentieiis. 
Through the courtesy of Mr. Hartert and Prof. W. Blasius we have been able 
to compare four adult males of the supposed hill-form (including the type of dissen- 
tient) Avith Lvo adult males of the lowland bird (including the typo of plateni), one 
specimen of each being already in the Sarasin Collection; these seem to be the 
only adult males known at present. The four hill-specimens proved to bo a shade 
browner than the type oi plateni, so confirming Hartert’s opinion, but the Sarasins’ 
specimen of the lowland form (Macassar) is intermediate, or even stands nearer to the 
birds from the hUls. This is not sufficient, however, to disprove the existence of 
Hartert’s supposed hill-race, on the other hand we believe that an average of many 
specimens from both spots will ultimately prove the existence of an almost inappre- 
ciable local differentiation, showing that the hill -birds stand a shade nearer to 
G. frenatus saleyerensis than to G. frenatus < saleyerensis of the plains of South Celebes. 
A formula is therefore required for the hill-birds, and it is an easy matter to propose 
such symbols, but not easy — indeed impossible to us at present — to suggest one 
which we could be sure would be the best. 
Were it not for typographical difficulties, one method for the purpose would 
be to adjust the angle of the sign O to answer the needs of the case : thus the
