30 NORWEGIAN JER-FALCON. 



of the bird is of a more or less pure white, ornamented 

 with spots of a dark slate-colour, approaching to 

 brown, which form longitudinal streaks on the chin 

 and throat, and narrow spots in front of the neck and 

 region of the crop, increasing in size towards the ex- 

 tremity of the feathers, where they appear like tears 

 or drops; they are of a deeper tint, and cordate 

 towards the tips of the feathers of the flank, and 

 lozenge-shaped towards the base, approaching the form 

 of the transverse bands more or less perfectly; on the 

 feathers of the legs are transverse spots or bands, 

 closer together. The markings of the under tail 

 coverts are of greater extent, less numerous, lozenge- 

 shaped, and often extended along the quill shafts in 

 the form of fine deep streaks. 



The figure of this egg is from the drawing of a 

 specimen in the British Museum.
