Distribution. The Indian countries, to Malacca, Java, Bali, and Sumba, S. China and Hainan, 
south throughout the Philippines to Borneo, and Celebes (see Salvador! 2 ^ Shelley 5, 
Blanford 10 , Styan 6 , Glrant 12, Hartert 75). 
In Celebes — Macassar (Wallace 5, Weber 4, P. & F. Sarasin 77); ? Togian

Among the two hundred and more specimens in the British Museum included 
by Capt. Shelley under the name C. merulinus , there is one marked: “cf ad. 
Macassar (A. B. AV all ace)”. This appears to be the specimen which was in 
the hands of Lord Walden in 1872 (hi), when he remarked that it appeared 
to belong to the group of which C. merulinus is typical. This determination 
has recently been confirmed by Mr. Biittikofer, who records two specimens 
obtained by Prof. Weber at Macassar, and is further proven by four specimens 
obtained by Drs. P. and F. Sarasin at the same spot. Still further east Shelley 
records a specimen from Ternate, but this indication is not accepted without 
query by Count Salvadori (Orn. Pap., Agg. Ill, 1891, 218). 
Shelley remarks that C. merulinus appears to consist of three races: viz. 
“C. merulinus (Scop.), a pale bird with the grey of the head and throat sharply 
defined and with clear regular white bars across the inner webs of the tail- 
feathers. C. threnodes Cab., a rather darker bird with a deeper rufous buff 
colour on the breast. C. sepulchralis (S. MiilL), with the upper parts nearly 
uniform, the notches on the outer webs of the tail-feathers shaded with rufous 
and the white bars on their inner webs nearly obsolete”. From the last-named 
form, writes Mr. Biittikofer (4), C. merulinus “should certainly be separated. 
It is distinguishable from C. sepulchralis by its smaller size (wing maximum 
103, tail maximum 108 mm), further by the very pale ash-grey colour of head, 
nape, sides of neck, chin, throat and upper chest, which colour extends on to 
the upper breast in certain individuals, and by the very pale ochre-yellow colour 
of breast, abdomen and under tail-coverts”. 
Mr. Hartert is of opinion that C. threnodes may also have to be separated 
again from C. merulinus.

In this genus, the species of which are about the size of a Turtle-dove, the 
tail is much longer than the wing, and the occipital feathers are length- 
ened so as to form a crest. Bill moderate, nostril a slightly projecting, 
oval formation of skin; wing short, secondaries about V 4 its length, tail strongly
