112 ARRIGONI LEGLI ODDI. 



verts pearl-groy slighter and sky-coloured on back, 

 broadly edged with biiffish on the latter part, with 

 brownish-black in the former ones, the four middle tail- 

 feathers of a fine pearl-grey and curled upwards ; the 

 rest lancet-shaped white siightly ash-grey in the middle ; 

 scapulars with brown and white zig-zags mnch more 

 faded than usual wich a large band on the outer web of 

 alight chestnut without zig-zags ; wing-coverts pearl-grey 

 brown edged, the greater with an almost white bar near 

 the end and tipped with blackish-ash ; primaries pearl- 

 white, pure white on the shaft, secondaries the same on 

 the inner web, the outer portion towards the end of the 

 outer web brown-black with very light green reflections, 

 so that there does not exist a speculum, but simply a 

 Space; the usual black bar is substituted by a pearl- 

 grey tint, but there is the broad terminal white bar: 

 inner secondaries greyish-pearl, the outer web of a pale 

 chestnut-brown ; lower breast, belly, vent and flanks as 

 normal coloured, but slightly whiter ; under tail-coverts 

 dark pearl-grey, broadly black at the top ; legs, toes 

 and their membranes orange-yellow. 



This handsome Drake was killed on March the 27"' of 

 this year in the Valle Cornio (Yen. Est.) by my friend the 

 well-known sportsman Signor Silvio Lugli, who has 

 given it me; at the same time I am very glad to present 

 him my best thanks for his kind gift. 



Our specimen is without doubt a wild Duck affected by 

 a true chlorochrostic anomaly very far from being comple- 

 ted, but, nevertheless, no less important and which pre- 

 sents on the colour of upper parts (back, rump and upper 

 tail-coverts) much resemblance with ih^ chlorochrostic-isa- 

 belline variety of which I am now speaking, but at lirst 

 sight one can see the differences between them, since our 

 specimen is quite a grown pale Duck namely without any 

 character of isabelline variety. It seems to me that this 

 anomaly must be rightly classified amongst these com- 

 monly named Grey Blackbirds, Grey Blackcaps, Grey 

 Redbreasts, Grev Coots and others.
