The male of lylei (type specimen in Washington) differs from the 

 corresponding sex of flavinucha in the decidedly paler yellow of its 

 chin and throat, the lesser suffusion of orange in the nuchal crest, the 

 tendency of the black streaking to invade the center of the throat, and 

 (apparently) in its shorter wing length; the two agree in having the 

 dark streaks of the f oreneck almost black and the apical third or half 

 of the maxilla pale-colored (at least in the dried skin). The birds 

 of northwestern Thailand have, in most cases, the characters of lylei 

 but certain individuals show approach to flavinucha in having a rather 

 longer wing and a deepening of the colors of throat and crest. I have 

 been unable to compare females of the two forms.

olophus annamensis R. Meinertzhagen 1924. 



The present subspecies probably has in our provinces a distribution 

 identical with that of Picus chlorolophus laotianus. Specimens taken 

 by Eisenhofer at Huai Pu, May 20 and 29, 1912, are in the museums 

 at Hannover and Stockholm; I have examples from Ban Bo Thong, 

 Ban Pha Lai, and Phu Kha. 



The Phu Kha bird was found in the evergreen at about 4,500 feet 

 but otherwise this form is known only from the dry, deciduous for- 

 ests of the lowlands. Gyldenstolpe considered it very common in such 

 jungle at Den Chai and Pak Pan. 



This race cannot be distinguished in the field from lylei; direct com- 

 parison in the hand shows the dark streaks of the foreneck to be deep 

 brown rather than brownish black. 



P. f. archon is a poorly defined form. From pierrei and the birds 

 of eastern Thailand usually placed under that name, it is at once sep- 

 arable by its having the apical third or half of the maxilla pale- 

 colored in the dried skin. From lylei it seems to differ only in having 

 the dark streaks of the foreneck deep brown, not brownish black, a 

 distinction particularly well marked in the female specimens before 

 me.
