 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 \ 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 Azarce, 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.
