Victoria Crowned Pigeon. Goura victoria. Plate XI. 



This fundus oculi is of the gray color, seen generally in pigeons 

 and doves, and covered with minute white dots. On the upper and 

 nasal side of the fundus is the macula, a small dull-gray area sur- 

 rounded by a gray and green reflex of small lines. The optic disc is 

 long, narrow, boat-shaped and somewhat rounded at the upper end. 

 It looks as it were rather hollow and gray in the centre with a white 

 rim all around. A network of small, brown, pigment dots is dis- 

 posed along the centre on either side of the pecten; and some opaque 

 nerve fibres extend across the fundus on all sides of the nerve. 



The pecten is of the usual dark chocolate tint. It is corkscrew- 

 like in appearance, but one end is rather club-shaped and looks as 

 if it were covered with small brown nodules. This segment conies 

 more prominently forward towards the lens.

 Crested Coot. Fulica cristata. Plate XII. 



The predominant color of the eyeground is dull gray, every- 

 where sprinkled with minute, white dots that are more clearly seen 

 above the superior termination of the optic nerve and to the nasal 

 side of the pecten. 



The long optic disc is white, with a few tiny pigment dots about 

 its margins. The pecten is lighter brown than in the majority of 

 birds; it is very large, almost hiding the disc from view. Many 

 opaque nerve fibres radiate from the papillary circumference and 

 extend several disc breadths across the fundus.
