N° 1434 of my Collection. — Yonng male. — Semi- 

 albino variety. 



It is ordinary in sizc : the chin spot is rather large, but 

 of snch exten sion onc finds in many qnite normal speci- 

 mens ; on thc neck, wlierc the black tint one scarcely 

 secs, WC find a fcw cntircly white feathers on the anterior 

 and lateral parls : gcneral colour bright enongh ; it exists 

 the white abdominal spacc; the feathers of underparts are 

 here and there edged with a brighter colour. 



This young specimcn was killed by the swivel-gunner 

 I. Minotto, on JNlarch 4'" 1896, not very far from Venice. 



I have put in a special list thosc Anatichv which otfer 

 only an abnormal white coUar, rcmaining in the rest of 

 the ordinary colour, because the gcneral sliglitly faded 

 tint and other not very important ditferences could dcpcnd 

 from thcir agc or the season in which they were killed : 

 in factthey are only observed in the two specimens caught 

 in thc months of August, in which epoch remains of 

 summcr-dress can again be found. Last ycar 1 have 

 spoken (1) on this anomaly then observed only in the 

 Ni/roca afncana and addcd a plate to cx})laiu this intcres- 



(1) Nota sopra una varieta di Nyroca africuna [Alli Soc. ilal. sc. nal., 

 vol. XXXVl, wilh plate, 1807).
