It has a fine whistling note which it utters both when flying or when perching at a top 
of a high tree. 
The most southern locality where I met with this species was at the neighbourhood 
of Koh Lak, but down there it was rare and only a few specimens were observed. These 
southern birds seems to be of a paler grey colour than specimens obtained in the northern 
localities but are still not worthy of separation as a distinct race.

Among the Cuckoo-Shrikes collected at Koh Lak in the Siamese Malaya there is 
a specimen which I have referred to the above-mentioned race of V. melachistus, on 
account of its having the under tail-coverts pure slaty grey and exactly of the same colour 
as the rest of the under surface. The central tail-feathers are also black with a greenish 
gloss und have a broad white tip. On the inner side of the primaries, except the first one, 
there are large white patches. The under wing-coverts are almost pure white though 
spotted and barred with grey. 
129. Volvocivora lugubris saturata. Swinu. 
do Koon Tan 5/9 1914. L= 215 mm; W=117 mm.; T=111 mm.; C= 13,2 mm.; Tarsus = 19 
mm. — Irides: brown. Bill: black. Legs: black. 
A single specimen of this species was obtained in a mixed pine- and oak forest in 
the Koon Tan mountains. 
This specimen perfectly well agrees with SwINHOE’s description. 
In Siam it seems to be rare and it has not been recorded from that country before.

This race which I think is quite distinct from the typical V. m. melanoptera was 
found in Northern Siam as well as in the Siamese Malaya. At this latter locality two 
specimens were collected: one male in full plumage and one female. This latter speci- 
men has the underparts of the body, with the exception of the pure white under tail- 
coverts, barred with greyish brown more closely on the chin and throat.
