Coracina sulphurea.

Great Comoro; iid. Ann. Sc. Nat. Zool. 1887, p. 228; iid. N. Arch. 
Mus. H. N. Paris (2), x. p. 260, pl. 7, fig. 1 (1888) ; Sharpe, Handl. 
iii. p. 291 (1901). 
Similar to C. cinerea, from which it differs in the head and neck being 
dusky grey, only slightly darker than the remainder of the upper parts and 
like them tinged with sulphur yellow; greater wing-coverts and secondaries 
with yellowish white margins; crop, breast and under tail-coverts and the 
pale ends to the tail-feathers sulphur yellow. Total length 8:7 inches, 
culmen 0:65, wing 4:1, tail 3°65, tarsus 0:95. Great Comoro Island 
(Humblot). 
A second specimen has been described as intermediate between the type 
of this species and C. cucullata, having the head and neck blacker and the 
under parts paler yellow. 
The Sulphur-breasted Cuckoo-Shrike is a native of Great 
Comoro Island. 
The species was discovered by Monsieur Humblot, who 
obtained several specimens on the island. It appears to me 
probable that these two specimens, above described, are 
adult male and female, as they have no dark bars on the 
plumage, which is the sign of immaturity in members of this 
genus.

Adults. Very similar to C. cinerea major, from which it differs in having 
the breast, under tail-coverts, under wing-coverts and inner margins of the 
quills pure white, the dark grey thighs appearing in strong contrast. Total 
length 8:5 inches, culmen 0:75, wing 3°75 and 3:95, tail 3°8, tarsus 0°85.
