622. HYPOCRYPTADIUS CINNAMOMEUS Hartert. 

 CINNAMON HYPOCSYPTADITTS. 



Hypocryptadius cinnamomeus HABTEBT, Bull. Brit. Orn. Club (1903), 14, 

 13; MCGBEGOB and WOBCESTEB, Hand-List (1906), 96; GBANT, Ibis 

 (1906), 473, pi. 18, fig. 1. 



Mindanao (Goodfellow, M earns). 



Male. Above bright cinnamon-rufous; wing-feathers and rectrices 

 blackish brown with most of the outer webs cinnamon-rufous; inner webs 

 of primaries and secondaries cinnamon; under parts buff, tinged with 

 cinnamon on breast, and becoming lilac-gray on lower breast and abdomen, 

 and nearly white on crissum ; thighs darker. Wing, 90 ; tail, 54 ; culmen 

 from base, 16; bill from nostril, 10; tarsus, 21. 



The female is similar to the male. This species is known only from 

 Mount Apo, Mindanao. 



Family DIC-EID-Sl. 



Bill short, rather broad at the base; cutting edges of both mandibles 

 finely serrated for at least the distal third ; first primary usually wanting ; 

 tail short and square. Birds of this family resemble the Nectariniidce and 

 differ from all other Passerifonnes in the finely serrated tomia. The 

 species are all small resident birds. Some are brightly marked with red 

 or yellow, while others are plainly colored. They feed about flower or 

 fruit trees or vines in the manner of the sunbirds. 



Genera. 



a 1 . Bill longer and more slender; width of upper mandible at base not greater, 

 usually much less, than bill from nostril; tail shorter, not extending beyond 

 the toes. 



6 1 . Bill more slender, the terminal half decidedly compressed; outline of gonys 

 nearly straight; culmen from base at least twice the greatest width of 



upper mandible; short first primary wanting Dicaeum (p. 622) 



6*. Bill stouter, and decidedly broad nearly to the tip; outline of gonys convex; 

 culmen from base less than twice the width of upper mandible. 



Prionochilns (p. 637) 



a*. Bill shorter and stouter; width of upper mandible at base greater than length 

 of bill from nostril; tail longer, its tip reaching beyond the toes. 



Piprisoma (p. 641) 



Genus DKLEUM Cuvier, 1817. 



The genus Dicceum is distinguished by the slender and sharply pointed 

 bill, by the comparatively short tail, and by always lacking the first 

 primary. The shape of the bill alone is enough to distinguish Dicceum 

 from either Prionochilus or Piprisoma, for while the base of the bill is 

 stout in all three genera, in Dicceum its distal portion is much com- 

 pressed, slender and sharply pointed, and the outline of the gonys is but 

 very slightly convex.
