This is one of the most magnificent of the Trogons inhabiting the Old World, and is distinguished from 

 all its congeners by the freckled markings of the outer tail-feathers — a character in which it assimilates to 

 some of the American members of the family. 



The Harpactes Diardi must be a most conspicuous object among the leafy branches of the trees in the 

 parts of the Old World wherein it is destined to dwell. These are Malacca, where it was obtained by 

 Mr. Wallace ; the island of Sumatra, specimens from whence, formerly in the collection of the Baron 

 Laugier, are now in the British Museum ; and Borneo, where it appears to be very numerous — that is, if 

 we may conclude so from the many examples which are sent to Europe, either direct or by way of 

 Singapore. Some slight differences occur in the colouring of specimens from the various localities above 

 mentioned, but are not of sufficient importance to entitle them to be regarded as distinct. Some have 

 the crown of the head of a deep red, while the same part in others is reddish black ; some have a faintly 

 indicated crescent of white separating the black of the throat from the scarlet of the abdomen, while in 

 others the black and scarlet meet abruptly. I at one time considered that the Malacca birds could be 

 at all times recognized by the lighter colouring of the upper part of the breast ; but I have a specimen 

 from Borneo in which it is as apparent as in those from the Malayan peninsula. 



The female, as will be seen on reference to the Plate, has the head and chest brown, in lieu of the deep 

 black colouring of the opposite sex, and freckles of brown and yellow on the shoulders and wing-coverts, 

 instead of black and white ; in other respects her colouring is very similar. 



I am indebted to Mr. Wallace for a knowledge of the colouring of the soft parts of this species, the parti- 

 culars of which he kindly transmitted to me in a letter dated Singapore, September 30, 1854; unfortunately 

 he did not at the same time furnish me with any account of the bird's habits and economy, which will 

 doubtless, when known, prove highly interesting. 



The male has the crown of the head deep blood-red in some specimens, reddish black in others ; throat 

 and chest black ; on the nape a band of rose-pink ; back and upper tail-coverts dark sandy brown ; wings 

 minutely barred with wavy lines of black and white ; primaries black ; breast and under surface carmine-red, 

 separated in some specimens from the black of the throat by an obscure crescent of white; two middle tail- 

 feathers rich chestnut-brown, with a bar of black at the tip, the next on each side black, the remainder 

 black at the base, and freckled for the remainder of their length with black and white ; bill blue, with the 

 oilmen' and tips of the mandibles black ; gape and orbits purplish violet. 



The differences of the female have been pointed out above. 



The Plate represents the two sexes, of the size of life. The plant is the Hoya coriacea.
