mandible; the remaining underparts pale fulvous, marked on the 

 breast with elongated black spots, on the abdomen with faint brownish 

 streaks, and on the sides with indistinct blackish-brown bars; the 

 under tail coverts light crimson, indistinctly barred and spotted with 

 blackish brown. The adult female differs in having the entire crown 

 black. Immatures of either sex have the feathers of the crown black, 

 tipped with crimson. 



Ticehurst has adduced reasons (Ibis, 1939, p. 5) for considering 

 atratus conspecific with macei, but the arguments advanced by him 

 may with equal propriety be employed to show that the lowland 

 macei should be coupled with the similarly lowland longipennis. It 

 is significant that Chiang Mai specimens differ from topotypical longi- 

 pennis in having the underparts a deeper fulvous, the spots on the 

 breast smaller and less numerous, the streaks on the belly almost 

 absent, the under tail coverts more crimson than pink — in all these 

 characters approximating macei. To the objection that macei has the 

 upper tail coverts and central rectrices unmarked black while longi- 

 pennis has them barred with white, I need only point out that the 

 same variation is exhibited among the races of Dryobates canicapillus 

 (cf. semicoronatus and canicapillus).
