Yellow-throated Dicaeum.
Dicceum dorsale, Sharpe, ‘Nature,’ August, 1876, p. 298.—Id. Transactions of the Linnean Society, 2nd series,
Zoology, vol. i. part 5.
T h e Malayan archipelago is the metropolis o f the Diceidce, where nearly every island seems to posses as
peculiar species; and in the Philippine Islands occur the representatives of a complete section of the above-
named family. These might be called the “ black-and-white ” Flower-peckers; and the two beautiful birds
already figured in the present work on the Plate of D. retrocinctum are characteristic species of this section.
Since that time Dr. Steere has discovered during his visit to the Philippines two more species—■D . hasmato-
stictum, Sharpe, from Guimaras and Negros, and D. hijpoleucum, Sharpe, from Basilan and Malamaui; so
that we now know of four o f these pied Diceidce in the above-named archipelago. I mention these birds, as
I am anxious to correct an error into which I was led when treating o f D. retrocinctum in the present work.
I figured on the Plate of the latter species two birds which I considered might be the sexes o f one and the
same species, although I hinted that there might be two bird s; and this seems to be the case, as both Mr.
Sharpe and Count Salvadori have examined the question, and regard the supposed female o f D . retrocinctum
as the species long ago described as D. papuense by Gmelin.
The most characteristic representative of this group is D. trigonostigma, a species widely spread over the
Indo-Malayan subregion, and occurring plentifully in Borneo ; it was also found by Dr. Steere in Negros.
The present species, called by Mr. Sharpe dorsale on account of the red spot on the back, is from the
island of Panay, where, according to Dr. Steere, it was “ shot in the highest part of the island, in the
remains o f the virgin forest on the highest range o f the mountains west o f Ilo llo.” It is easily distinguished
from D. trigonostigma by the orange-red colour of the back being confined to the mantle instead of
the whole back being yellow, and also by its entirely yellow throat.
The following is a translation of Mr. Sharpe’s original description :—
Above bright slaty-grey, the head rather b rig h ter; interscapulary region orange-red ; wing-coverts uniform
with the back, the outer ones edged with olive; quills blackish, externally margined with the same
colour as the back, a few o f the secondaries edged with olive, the innermost uniform with the b ack; upper
tail-coverts slaty g re y ; tail black, the feathers margined with slate-colour; lores black; sides of the face
dark slate-colour; below very bright orange, the throat and lower abdomen yellow; thighs inwardly grey,
externally yellow; bill blackish, the lower mandible paler towards the base; feet dark brown. Total length
3'5-inches, culmen "5, wing T9, tail T05, tarsus ’55.
The female is olive-green above, the rump rather more yellow; sides of face uniform with the h e ad ;
below bright yellow, the breast and under wing-coverts more richly coloured. Total length 3%7 inches,
culmen ‘5, wing T9, tail -9, tarsus *55.
The figures are taken from the typical birds procured by Dr. Steere in Panay, and kindly lent to me by
him before his return to America.
