The specimen recorded (1915, 1920) by Gyldenstolpe is an imsexed, 

 undated bird, collected in "Siam" by Eisenhofer and now deposited 

 in the museum at Hannover. The type of "rileyi" was taken by Smith 

 on Doi Ang Ka, 7,000 feet, December 6, 1928, while the sole paratype, 

 from the same mountain, was shot on the same day at 8,400 feet. The 

 only other examples known from Thailand are two gotten by de 

 Schauensee's collectors above 6,000 feet on Doi Pha Horn Pok early in 

 1938. The status of this form seems to be that of a rare winter visitor. 



It has the irides brown ; the bill yellow, with the culmen and basal 

 half of the maxilla (except along the edges of the commissure) black- 

 ish ; the feet, toes, and claws black. 



This large thrush appears black in the field, but in reality it has the 

 tipper plumage deep purplish blue (the remiges and rectrices brighter) , 

 the feathers of the head and mantle with glossy tips of a lighter pur- 

 plish blue; the front, forecrown, and lesser upper wing coverts 

 (shoulder patch) shining cobalt blue; the median upper wing coverts 

 with white or violet-white tips ; the underparts black, washed with deep 

 purplish blue, the feathers of the throat, breast, and upper abdomen 

 spangled like those of the head and mantle ; the feathers of the lower 

 back, flanks, and lower abdomen with concealed pure white bases and 

 shafts; the undersurface of the remiges and rectrices black.
