Diagnosis. Standing near the typical C. frenatus, but 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 ^ 7, Wall. 



g 3, I 1); Manado tua, Mantehage, and Banka Is. (Nat. Coll.); Gorontalo District 



(Guillemard i 1); Togian Id. (Meyer ./ .3); East Celebes (Nat. Coll.); South-east 



Celebes — Kandari /Beccari h 2). 



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

 Cyrtostomus frenatus <^ saleyerensis.

 Figures. W. Blasius p. I. 

 Diagnosis. Like C. frenatus saleyerensis, but the ohve of the upper parts with a shghtly 



greener tinge, the under parts deep yellow, almost as in the ty2}ical form. 

 Distribution. Lowlands of South Celebes: Macassar (Wallace 11, Platen p I, Weber q 2.

We have next to do with the bu-ds fi-om the Peak of Bonthain and the high- 

 lands around it, which have been named by Mi-. Hartert C. frenata dissentiens. 

 Through the courtesy of Mi-. Hartert and Prof. W. Blasius we have been able 

 to compare four adult males of the supposed hill-form (including the tyjie of dissen- 

 tiens] with two adult males of the lowland bird (including the type 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 be a shade 

 browner than the type ol plateni, so confirming Hartert's opinion, but the Sarasins' 

 specimen of the lowland form (Macassar) is intermediate, or even stands nearer to the 

 birds fi-om the liills. This is not sufficient, however, to disprove the existence of 

 Hartert's supposed hill-race, on the other hand we beheve 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 

 C. frenatus saleyerensis than to C. frenatus <C 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 <[ to answer the needs of the case : thus the
