Nest. Cup-shaped, the size of a Chaffinch's, rather loosely built of moss and coarse straw- 
like strips of dead grasses or. wood, ornamented externally with a few large seeds, 
fined with fine root-fibres. Placed on the twigs of a tree. Height 50, breadth 65, 
breadth of pocket 52, depth of pocket 38 mm (Manado, Jlr. 83: Meyer). 
Breeding season. This nest was taken in March, 1871, and contained two nestlings. The 
number of eggs is, therefore, probably only two, which were laid in this case in 
Pebruary. 
Distribution. Celebes: — Minahassa (Wall. 4, M. 5, etc.); Manado tua, Mantehage, Lembeh, 
Banka off the Minahassa (Nat. Coll, in Dresd. Mus.); Hill-forests between the 
IVIinahassa and Mongondo (P. & F. Sarasiii); Gorontalo Distr. (Meyer 5)\ Togian 
Islands (Meyer 5); Kandari, S. E. Celebes (Beccari 2]\ W. Celebes (Doherty 17); 
Centr. Celebes, Mapane (P. & E. S. 14); E, Celebes (N. C.); small island off Buton Id. 
(S. Miiller «i); S. Peninsula (Wallace 4, Platen S, etc.); Palopo at head of Gulf 
of Boni (Weber 12); Poling and Banggai Id. (N. C.); Sula Islands (Allen hi, 4, 11). 
The common Blue Flycatcher of Celebes and Sula is a very distinct form 
most nearly allied to H. rotvleyi (Meyer) of Great Sangi. H. rowleyi differs in 
having the upper parts much darker blue and the under surface uniform bluish 
cinereous, and in its much larger size. JI. occipitalis (V ig.), the range of which 
is given by Sharpe (Cat. B. IV, 276; Ibis 1890, 276) as from Tenasserim to 
Flores, Borneo, and the Philippines, is easily distinguishable by its black joectoral 
collar and black nuchal patch; this form appears to be only subspecifically 
distinct from H. azurea (Bodd.) of Burmah and India. From its well marked 
differences II. puella might be regarded as a rather ancient inhabitant of Celebes. 
The genus IIypothymi<i forms another connecting-band between Celebes and 
the Oriental Region, no Flycatcher of this genus being known in Australasia,
