30 ARRIGONI DEGLI ODDI. 



Pinlail biit with a rieh grccn tiiil on some of the laterals; 

 tail brownish edged with yellowish-brown, the central 

 feathers darker and lengthened as is often seen in young 

 male Pintails at that age, in which they have not yet 

 assumed the long black feathers. Total length abont 

 20 inches, the two long middle tail feathers exceeding 

 abont 0.63 inches the laterals inclnded ; wing 8.60 ; tail 

 4.3 ; bill from foreiicad 1.85 ; tarsns 1.45 ; middle toe and 

 claw 1.86. 



This specimen, which seems to have been prepared 

 since a long time, has like the Pintail the shape, crown, 

 nape, the signs of the two stripes on hind-neck, zig-zags 

 on Upper parts, npper wing-coverts and partly the tail ; 

 like the Teal it has the speculnm, green tint on sides of 

 nape, the signs of the light lines under eye, spots on 

 breast, the zig-zags on sides of breast and abdomen and 

 is withont the space on sides of vent and of under tail- 

 coverts (see c^ Pintail), it has also some of the lateral 

 feathers of the latter. 



The wing-specnlum in this hybrid is precisely like that 

 noticed in the 9 hybrid between the Pintail and Teal of 

 my Collection(N''" 1062, January 1887 — Valle Morosina, 

 killed by Mr. B. Düse); in fact (1) the wing-coverts in 

 last row are tipped with light buff, the speculum half 

 black and half green placed one above the other, only 

 in mine there is a slight brass tint, Ihe tertials also are 

 like the hybrid above mentioned, the bill is like that of 

 Pintail ; other comparisons cannot be made as my spe- 

 cimen is a female, but the wings being alike is of no 

 common importance. 



Six hybrids of this kind have been described in the 

 appreciated monography of M. Suchetet (2), namely : 



cf and 9 iii the Collection of Mr. van Wickevoort- 

 Grommelin at Hartem, caught in Holland, the cf Fe- 

 bruary 25'" 1868 and the 9 October 2"^ 1888.
