Distribution. Nortli Celebes: Gorontalo (Forsten 2); Mnaliassa — Kakas, 2000 ft. ca. 
(Meyer 5), Eurukan, 3000 ft. ca. (Platen in Mus. Nebrkorn), near Lake Tondano, 
2oOO ft. ca. (Nat. Coll, in Mus. Dresd.), Tomohon 2500 ft. ca. (P. & F. Sarasin); 
Tonkean, E. Celebes (Nat. Coll.). 
The Blue Cuckoo-shrike of Celebes appears, as Gould remarks, only to 
inhabit the mountains, this surmise receiving confirmation from the specimens 
obtained since by Dr. Platen, the Drs. Sarasin and by our native hunters in 
North Celebes. No specimens up to the present have been recorded from the 
lowlands. 
In his “Studies of the Campophaginae” (2) Dr. Hartlauh rightly speaks of 
this species as quite aberrant in coloration. It is the only blue Graucalus. It 
is also remarkable as having the tail as long or longer than the wings. In this 
respect it agrees with G. caeruleogrisem (Gray) of New Guinea, Aru and Jobi, 
a form which also corresponds best with G. temmincki in colour, being bluish 
slaty, but in bulk it is twice as big. G. caeruleogriseus again bears much resem- 
blance to G. bogeri of New Guinea, as Salvadori points out, but this form 
seems to be less nearly related to the Celebes species. G. temmincki must be 
regarded as a very distinct species, having its nearest affinities in Papuasia, and 
its presence in Celebes may not be easy to account for.
