THE BIRDS OF NORTHERN THAILAND 361 



The Lao black-necklaced garrulax is widely distributed over the 

 lowlands of the provinces east of the Khun Tan range. Eisenhofer 

 sent to Hannover a male from Pha Hing, May 5, 1912, and to Stock- 

 holm an unsexed skin from Huai Pu, May 24, 1912; Gyldenstolpe took 

 it at Den Chai and Pha Kho and I found it at Chiang Saen Kao. 



Gyldenstolpe records that, near Pha Kho, "a nest containing 3 pale 

 blue eggs was found ... on the 16th of April 1914 . . . The nest was 

 placed in a low tree within a bamboo-jungle and could easily be 

 reached from the ground." 



Gyldenstolpe's birds had the irides yellow or yellowish red; the 

 bill horn color ; the feet and toes plumbeous-gray. 



G. m. schauenseei differs from fuscatus in having the upperparts 

 generally, but especially the nuchal collar, deeper in color ; the rectrices 

 tipped with dark buff, not buffy white.

This laughing-thrush is rather common in heavy evergreen from 

 3,300 to 5,500 feet but has until now been found in our provinces only 

 on those few peaks of the Khun Tan and Thanon Thong Chai ranges 

 that are listed above. 



If it did not possess in full measure the curiosity characteristic of its 

 genus, the present species would be known only by scratching sounds 

 and conversational calls proceeding from ravines and thickets. In- 

 trusion on its haunts, however, at once produces a clamor like that 

 of species already dealt with, and individual birds climb up the vines 

 for a nearer view before ducking again into the foliage. De Schauensee 

 (1929) records that it has a loud, clear, whistled song of three short 

 notes on the same pitch, followed by a longer note three tones lower. 



A male from Doi Suthep, March 23, had the gonads enlarged ; an- 

 other from Doi Ang Ka, April 27, had them greatly enlarged. Speci- 

 mens in postjuvenal molt have been taken between September 3 and
