less cm-led, fewer metallic spots on the tlirout and breast, the under wing- coverts 

 usually more spotted with white (2 ?, Kema, Feb. 1894: Sarasin Coll., and others).

The largest and smallest specunens of the group a are both from the mainland 

 of Celebes. Those with recurved bristles sprouting from the forehead (six in number) 

 — apparently the oldest — are also on an average the largest specimens (wing 

 160—168), though the largest of all from Celebes (wing 169) has no such bristles.

Eggs. 



Nest. 



"Dr. Platen sent me a clutch of 2 eggs of this bird from Rurukan in the Minahassa, 

 measuring 33x21 mm, and like most of the members of the genus much elongated. 

 The ground-colour is white, marked with only isolated underlying spots — some 

 very small, others very large — of pale violet, and with superjacent spots — some 

 light red, others dark brown, which unite into a circlet at the blunt end. The shell 

 has httle or no gloss" (Nehrkorn MS.). 



Two eggs (one broken) in the Sarasin Coll., accompanying a nest, differ con- 

 siderably from Ml-. JSTehrkorn's description; they are white in ground-colour, finely 

 peppered all over with shell-spots of pale lilac and sui-face- spots of a browner tint, 

 none of the spots larger than an ordinary pin's head and most of them minute points 

 only, slightly more conglomerated towards the blunt end of the egg: broad oval — 

 29X21 mm (Tomohon, 19. April 1894). 



The Sarasins obtained two nests: one with the above two eggs, the other containing 

 a nestling ("there were probably two"). They are broad, deep saucers: internal diam. 

 c. 90 mm, depth c. 40 mm, lightly built of vegetable fibres and roots, with a few bits 

 of sticks intermingled in the base and sides, lined with finer dark root -fibres. The 

 structure is cleverly suspended between the jjrongs of a forked branch. 



Dr. Platen writes {d 6): "I found the nest twice on a bough stretching across 

 a busy road at a height of 4 — 5 meters, where it was suspended in a foi-k after the 

 manner of Iniilding of the Orioles".
