In Java it is probably entirely replaced by JE. mystacalis, while in all the known portion of 

 Borneo it is a common species, frequenting, according to Mr. Wallace, the mangrove swamps. 



In the latter island it has been collected at Banjermassing by Mr. Motley, at Sarawak by 

 Doria and Beccari, at Marup, Sibu, and the Matu beach by Mr. Everett, and in Labuan and on 

 the opposite mainland by Mr. Low and Governor Ussher. 



One of the specimens collected by Mr. Everett at Sibu, on the 7th of January, 1875, a male, 

 in apparently fully adult plumage, differs from all the other specimens which I have examined 

 in having the lower breast, abdomen, and under tail-coverts of a dusky olive-yellow, and the 

 yellow patch on the lower back rather strongly mottled with scarlet ; this latter character I have 

 met with in a specimen of 2E. vigorsi, and do not regard as of specific value. The peculiar 

 colouring of the abdomen would appear to be of more importance ; yet I think it may have 

 occurred from some accident in the moult ; and only being aware of a single specimen thus 

 marked, I consider that it would be premature to separate it from the other specimens collected 

 at the same time, with which I have compared it. 



This variety I have figured as well as a typically coloured adult male collected by Mr. Everett 

 at Sibu in January, and a female from the coast opposite Labuan, from which specimens my 

 descriptions have also been taken. 



Much confusion has arisen amongst naturalists as to the correct title for this species, so that 

 a few remarks upon this subject may be of service. 



The name of mystacalis, Temm., belongs to a distinct Java species ; that of siparaja, Raffles, 

 was applied to the Sumatran bird ; and lathami, Jardine, probably belongs to the Malacca bird, 

 to which Cabanis afterwards gave the title of eupogon. These three latter names the Marquis of 

 Tweeddale has already proved to be synonymous. Reichenbach's chalcqpogon from Borneo, 

 though described as having the crown green, is figured with that part violet, and certainly belongs 

 to this species.
