11 specimens (10 cf, 1 9)- 



Adult male: »Iris orange-red, a very narrow inner 

 edge pale ochre , bare skin round the eyes madder- red , 

 gular skin pale chrome-yellow with an ultramarine cross- 

 band , bill horny white , feet slaty black.' ' 



Young male (with only one faintly developed fold on 

 the ridge of the culmen) : »lris orange-red, inner edge 

 mixed with brown , bare skin , bill and feet like in adult 

 male. Plumage black , only the superciliary region inter- 

 mixed with yellow feathers." 



Adult female (with five folds on the culmen) : » Iris fox- 

 red , mixed with brown , a narrow inner edge sulphur-yel- 

 low, bare skin round the eyes wine-red, gular skin pale 

 blue , with a violet-blue cross-band , bill and feet like in 

 adult male." 



Native name: •»Angang mussin.'^ 



The deep blue cross-band on the gular pouch in the dried 

 skin of some specimens is scarcely perceptible , though Dr. 

 Klaesi has very minutely mentioned it in all his speci- 

 mens. I feel therefore pretty sure that the specimen col- 

 lected by Mr. Forbes in Sumatra and mentioned by Mr. 

 Nicholson (1. c.) as Rh. suhruficollis will belong to Rh. 

 undulatus.
