plumage by tlieir much larger size. The tail lyre-shaped 

 and strongly developed ; colour rufous, strongly and broadly 

 barred with deep steel-blue. (1) with a single testicle present 

 on one side and an ovary on the other ; (2) with the ovary 

 only partially developed on one side and two superimposed 

 testicles on the opposite side. 



Phasianus reevesi, J. E. Gray. 



Hermaphrodite. Bred in an aviary at Brighton. Messrs. 

 Brazenor Bros. (Skin). Tail like that of the male both 

 in size and shape, but uniform deep wood-brown in colour ; 

 rest of the plumage a mixture of yellow, white, brown, 

 and grey, unlike the normal plumage of either the male or 

 female, and with a washed-out appearance. A spur on 

 one leg only. On one side a normal ovary was present and 

 on the opposite side a large testicle. 



Dr. H. Hammond Smith (introduced by Mr. Ogilvie- 

 Grant) exhibited the skins of three cock Pheasants assum- 

 ing the plumage of the female. These birds had all been 

 shot by Mr. A. N. Gilbey at Swakeleys, near Uxbridge, in 

 December 1910 and January 1911. In 1906 Mr. G. S. 

 Shattock and Dr. C. G. Seligmann had read a paper at the 

 Pathological Society describing a live cock Pheasant that 

 showed, in his tail-feathers only, a tendency to assume female 

 plumage, the distal part of the feather retaining the male 

 character, while the proximal portion assumed that of the 

 female. In all the three birds shown by Dr. Ilammond 

 Smith a similar change in the markings of the tail-feathers 

 was to be seen, while in the two birds which most resembled 

 females the tails were considerably shorter than those of the 

 ordinary cock Pheasant; except for this the change of plumage 

 was most marked in the feathers of the head and neck. In both 

 cases the sexual glands had been most carefully examined by 

 Mr. G. S. Shattock, who reported that they were normal in 

 character, and could not microscopically be differentiated from 

 those of an ordinary cock Pheasant, though it must be remem- 

 bered that at that time of year they were not functionary.
