NEW SPECIES OF BIRDS. 19 



Adult male: Upper surface as in D. dorsale but the rump quite 

 heavily washed with olive green. Chin, throat and upper breast 

 light bluish ashy grey, slightly paler on the chin and without the 

 yellow of D. besti. Two of our specimens, however, show a faint 

 trace of yellow on the chin. Rest of under surface yellow, slightly 

 deeper on breast as in D. pallidior. Flanks, abdomen and under tail 

 coverts much paler. Under wing-coverts, axillaries and inner webs 

 of quills wliite. 



Adult female: Upper surface as in D. besti. Chin, throat and up- 

 per breast grey, washed with yellow. Rest of under surface pale 

 greenish yellow, somewhat brighter along center of breast and ab- 

 domen, but not nearly as bright as in female of D. besti. Bill as in 

 male. 



Average measurements from nine males: Length, 3.9 inches. Cul- 

 men, .59. "Wing, 2.08, Tail, 1.03. Tarsus, .53. From tw:o females: 

 Length, 3.81. Culmen, .61. Wing, 1.96. Tail, .97. Tarsus, .65. 



Habitat: Sibuyan. 



19- Dicaeum intermedia sp. nov. 



Adult -male: Above as in D. dorsale. Rump shows very little 

 olive green wash. Chin and throat ashy grey uniformly washed 

 with pale yellow. Remainder of under surface as in D. sibuyanica. , 

 Bill black. 



Adult female: Above like female of D. sibuyanica. Below dirty 

 olive yellow, somewhat brighter on the abdomen. Bill paler than in 

 male. 



Habitat: Romblon, Tablas. It may ultimately prove that the 

 Tablas birds are distinct, the four specimens secured by us in that 

 island having a much heavier wash of yellow on the thtoat than the 

 Romblon birds. 



Five males from Romblon measure 3.75 inches in length. Culmen, 

 .55. Wing, 2.08. Tail, 1.09. Tarsus. .52. Three females from Tab- 

 las measure 3.62 inches in length. Culmen, .55. Wing, 1.92. 

 Tail, a. 02. Tarsus, .52. ' 



20. Dicaeum assimilis sp. nov. 

 Adult male: Above exactly like D. sibutense, but chin, throat and 

 fore breast very much lighter than sides of face, being clear ashy 

 grey, as in D. trigdnostigma. As Dr. Sharpe expressly states that 

 this is not the case in D. sibutense but that the latter species has 

 the throat like the sides of the face and head, it is evident that the 

 Sulu and Tawi Tawi (?) birds belong to a distinct species having the 

 back of D. sibutense and the under surface of D. trigonostigma.
