An adult male, collected at 2,100 feet on Doi Suthep, March 7, 1931, 

 and erroneously recorded by me as Cuoulus canorus, is the only speci- 

 men known from the North. 



The bird was found perched in a clump of bamboo at the edge of 

 light mixed-deciduous forest; its stomach was filled with hairy 

 caterpillars. 



It had the irides orange-red; the eye ring yellow; the maxilla 

 black; the mandible pale yellowish green, with black at the tip and 

 yellow at the base beneath ; the rictus bright yellow ; the interior of 

 the mouth bright orange; the feet and toes waxy yellow; the claws 

 brownish horn. 



This cuckoo is only with difficulty separated from the preceding 

 species. It has the bars of the underparts rather broader and bolder ; 

 the edge of the wing white, unbarred but sometimes suffused with 

 gray. 



Any specimen of the genus taken in Thailand should be sent to a 

 museum for expert identification, both because of the similarity of 

 the various species and because of the probable occurrence of still 

 unrecorded forms. 



My example is now deposited in the collection of the Princeton 

 Museum of Zoology. Charles H. Eogers has brought to my attention 

 the true identity of the bird and writes me that the chord of the 

 wing measures 182 mm., which clearly places it with the nominate 

 race.

The banded bay cuckoo is, in our provinces, an uncommon winter 

 visitor and a very rare summer resident. At Chiang Mai I found it 

 from October 31 (1936) to March 22 (1930), on the plain and on Doi 

 Suthep to 4,600 feet. Gyldenstolpe's bird from Pha Hing was taken 

 on April 11. I have winter examples from Ban Samoeng and Chom 

 Thong and a specimen taken at Wiang Pa Pao, August 1. Two males
