This species is evidently common in Trang, and we have 
received several specimens from the Lay Song Hong, a large 
lake or swamp in the interior of the State. Our specimens 
agree exactly with the types of the species from the Pakchan 
estuary in the extreme south of Tenasserim, while a skin 
collected by Lt.-Colonel Wingate in S.W. Yunnan differs in 
having had the base of the neck on the bare parts deep 
red instead of livid yellowish-white. Elliot (P. Z. S. 1877, 
p. 490) has already noticed this difference in certain Siamese 
birds, but it is improbable that the two forms are specifically 
distinct, the colours of the bare parts, as in other Ibises, 
varying greatly with age, sex, and season.

This is the third known specimen of an exceedingly 
rare Ibis. OustalePs type came from Cochin China, and 
Dr. Abbott obtained a second specimen in the interior of 
Trang, where he states that it was not uncommon in the dry 
season. We did not ourselves come across the species, and 
it was only with great difficulty that our collectors succeeded 
in obtaining a single individual. Our specimen (PI. I.) ? 
which, judging from the bill and feet, is an adult bird, agrees 
precisely with the type as described by Dr. Elliot, 
The dimensions are :— 
Wing 21*5 ; tail 10*5 ; bill along culmen 9*3; tarsus 4*4 
inches.
