DIC^EUM. 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."

 SIBUTTT FLOWERPECKER. 



Dicceum sibutuense SHARPE, Bull. Brit. Orn. Club (1893), 3, no. 12, 10; 

 Ibis (1894), 251, pi. 7, figs. 1 and 2; MCGREGOR and WORCESTER 

 Hand-List (1906), 97. 



Sibutu (Everett). 



"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. sibutuense 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 Dicceum sibutuense is as follows : "D. simile, 

 D. trigonostigmati, sed gutture saturate schistaceo, macula dorsale aurantiaca 

 distinguendum. Long. tot. 3.2 poll., culm. 0.45, alae 2.0, cauda? 0.85, tarsi 0.5."
