DICADUM. 631 
“A male from Sulu measures 89 in length; culmen, 13; wing, 52; tail, 
24.6; tarsus, 13.4. Two females from the same locality measure 84 in 
length; culmen, 12.7; wing, 50; tail, 24.6; tarsus, 12. We have only 
females from 'Tawi Tawi and can not be quite sure of the identification.”

SIBUTU FLOWERPECKER, 
Diceum sibutuense SHARPE, Bull. Brit. Orn. Club (1893), 3, no. 12, 10; 
Ibis (1894), 251, pl. 7, figs. 1 and 2; McGrecor and WorcESTER, 
Hand-List (1906), 97. 
Sibutu (Hverett). 
“This is an interesting species, new to science. Like D. trigono- 
stigma, it has a slate-colored throat, but the latter is blackish slate-color, 
like the sides of the face and head, and not lighter gray as in D. trigo- 
nostigma. The Sibutu bird, moreover, resembles D. dorsale in having 
an orange patch in the center of the back, the lower back and rump 
being slaty gray, slightly washed with olive, and not orange-yellow as 
in D. trigonostigma. The female, as might be expected, closely resem- 
bles that of D. trigonostigma, but is tinted with olive-green on the rump, 
and has not the orange shade of the hen of the last-named species.” 
(Sharpe.)* 
The figure of the female of D. sibutwense in The Ibis has a pale yellow 
patch on the back, a character which is found in no other Philippine 
species of the genus.

Male.——Somewhat similar to D. intermedium, the rump slate-blue like 
the back; chin lemon-yellow; throat lightly washed with yellow; entire 
breast orpiment-orange. Bill, legs, and nails black. A male from Bohol 
measures: Length, 89; wing, 48; tail, 23; culmen from base, 11.5; bill 
from nostril, 8; tarsus, 12.5. 
Female.—Above mouse-gray; rump washed with olive-green; lores 
blackish; cheeks, line around eye, and a narrow frontal band washed 
* Sharpe’s original diagnosis of Dicwwm sibutuense is as follows: “D. simile, 
D. trigonostigmati, sed gutture saturate schistaceo, macula dorsale aurantiaca 
distinguendum. Long. tot. 3.2 poll., culm. 0.45, ale 2.0, caude 0.85, tarsi 0.5.”
