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 Pakehan 

 estuary in the extreme south of Tenasserim, while a skin 

 collected by Lt. -Colonel Wiugate in S.W. Yunnan differs in 

 having liad 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. Oustalet's 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.
