A young bird caught by Mr. Butler and described by him in a letter 

 to me was '' Similar to the adult, except that the ring round the eye 

 was very narrow and tinged with fulvous. Bill and feet as in adults; 

 eye dark brown instead of reddish-brown." 



This teal is confined to the Audnman islands, hut Mr. C. W. Allan 

 shot a specimen of this species at Bassein, Burma, which was found 

 amongst a flock of AVhistling Teal on the 15th April, 1^1)8. This bird 

 was recorded in the Asian, and Mr. F. Finn wrote tome that he identified 

 the skin himself, and witlu'ut any doubt it was that of an Andaman 

 Teal. Nothing was noted as to whether the specimen was a drake or 

 a duck. It was probably driven on to the Burmese coast during 

 some storm, having ventured too far out to sea from the 

 Andamans. 



Nettion gibber /J rons, iV. castancum and N. alihigulare are very 

 closely allied; for a long time the first and the last were confounded with 

 one another, and even now it is by no means settled that A', cmtaneuui 

 and N. gibherifrons are not one and the same bird. The young males and 

 females are absolutely indistinguishabh^- but the adult male N.giljberifrons 

 has been found to attain a further jdumage, which, hitherto, no N. casta- 

 neum has been found to acquire. xV. albigulare differs from both these 

 Itirds in having the sides of the head darkcu- and more uniforni in colour, 

 and the darker streaks to the feathers ob.solete, but the main difference 

 lies in the Andaman Teal having the white ring round the eye, and the 

 first scconi'ary broadly edged with white.
