THE BIRDS OF NORTHERN THAILAND 231 



roads and even in the heart of villages. This is a shy bird that 

 probably often escapes notice among the canes, and little is known of 

 its habits in our area. 



In Nan Province I took specimens with the gonads greatly enlarged, 

 April 1 and 8, and a juvenile, June 8. 



Adults had the irides red or brown; the orbital skin slaty or 

 plumbeous ; the maxilla brownish black or dark brown ; the mandible 

 horny yellow, olive at the base, brownish black or dark brown at the 

 tip ; the feet and toes slaty green or dull olive ; the claws horny gray 

 or horn. 



The male has the crown and nape shining red ; the remaining upper- 

 parts bright golden olive-green with the rump and lower back bright 

 greenish yellow; the remiges and rectrices black, the former with 

 broken, narrow white bars; a supercilium and a broad malar streak 

 black mixed with white; the sides of the head otherwise gray; the 

 chin, throat, foreneck, and breast immaculate buffy yellow or greenish 

 yellow, much brighter on the sides of the lower neck ; the remaining 

 underparts buffy white or greenish white, each feather marked with 

 deep olive V-shaped bars, which give a scaly appearance. The female 

 differs in having the crown and nape black. The juvenile has the tips 

 of the primaries narrowly margined with white on the outer webs 

 and the underparts almost uniform in color. 



This form apparently was described from a unique example, cor- 

 rectly recorded in the original description as a female collected by 

 Gyldenstolpe at Pha Hing, April 9, 1914. In the same author's "Types 

 of Birds in the Royal Natural History Museum in Stockholm" (Ark. 

 for Zool., vol. 19A, No. 1, 1926, p. 74) , two specimens are listed, the first 

 of which is a male taken by Eisenhofer at Khun Tan in 1914. I have 

 examined this alleged cotype in Stockholm and found it both cata- 

 loged and labeled as "Typ," but since it was presumably not part of 

 an original series and first found mention in print ten years after the 

 formal description of the Pha Hing female, I cannot imagine what 

 standing as a type can be claimed for the Khun Tan specimen. Inas- 

 much as the birds to east and west of the Khun Tan chain may in 

 future require subspecific division, it is important that confusion not 

 arise in connection with the true type locality of eisenhoferi. 



In 1915 Gyldenstolpe added Picus xanthopygaeus to the northern 

 avifauna under the name Picus striolatus; no data were given, but the 

 example was said to be among the birds sent by Eisenhofer to 

 Hannover. This collection, made between February 7 and June 27, 

 1912, is now divided between the museums in Hannover and Stock- 

 holm. Search in both places failed to discover the bird, and I feel 

 certain that the record is due to misidentification of a skin of Picus 

 vittaius eisenhoferi, collected by Eisenhofer at Huai Pu, May 28, 1912,
