 Male. Crown of the head blackish brown, surrounded by a nar- 

 row stripe of white which unites with another line of white running 

 at right angles down the sides of the face ; beneath this a narrow 

 line of black which terminates in a point at the occiput, and running 

 over the eye joins a broader band of the same colour down the sides 

 of the face, is continued down the centre of the throat and spreads 

 over the chest ; sides of the head and neck white, interrupted at 

 the back of the neck by three longitudinal stripes of black, the centre 

 one being broad and the lateral ones narrow ; feathers of the back 

 and scapularies much lengthened, and conspicuously margined with 

 white, the centres being in some blackish brown, in others greyish 

 brown ; wings deep grey, with a beautiful green speculum, bounded 

 above and below with a narrow irregular band of white, produced by 

 the tips of the greater wing-coverts and secondaries being tipped 

 with that colour ; primaries brown ; rump and upper tail-coverts 

 greyish brown, finely freckled with zigzag lines of white ; centre of 

 the abdomen dull light chestnut brown, with a blackish brown mark 

 down the centre of each feather ; flanks and under tail- coverts blackish 

 brown ; tail brown ; irides brown ; bill reddish brown ; feet brown. 

 Female. Crown of the head, back and sides of the neck dark slate 

 grey, the sides of the neck regularly barred with minute lines of 

 greyish white ; the elongated feathers of the back and scapularies 

 margined with deep grey instead of white as in the male ; lower 

 part of the back deep slate grey ; upper tail- coverts the same, crossed 

 by numerous minute bars of white ; wings grey, the coverts tipped 

 with white ; sides of the face below the eye, throat, and all the under 

 surface rich reddish chestnut ; tail brown. 



Total length 18 J inches ; bill 1| ; wing 7 ; spur | ; tail 5 ; tar- 

 sus 1 J ; middle toe 2^. 



The female is rather less in all her admeasurements. 

 The male from which the description is taken had some of the tail- 

 feathers white, but this would seem to have been produced by wearing 

 and exposure, as they were all old feathers. 



Mr. Waterhouse observed, that the Fox contained in Mr. Bridges*s 

 Collection he felt little doubt is the Canis Azara, Pr. Max., but it 

 differed from the specimen figured in the ' Zoology of the Voyage of 

 the Beagle,' in not having the black on the chin and angles of the 

 mouth.
