bad; it had been frozen and, perhaps several times, thawed up 
and again frozen; thus the results of the examination may not 
seem quite free from objection. Two cases, apparently quite settled, 
are the following: a nearly two year old Leghorn fowl (Shattock 
and Seligmann 1903) and a Chinese pheasant (white ringed 
Formosan variety; Bond 1913). The fowl “exhibited a combina- 
tion of the external characters of both sexes; in comb and spurs 
it was male; in piumage chiefly female; it had evinced no sexual 
proclivities. On dissection two oviducts and two sexual giands were 
found. The left oviduct was fully developed, the right hypoplastic. 
The left sexual giand showed the tubular structure of the testicle 
but in a non-functional condition, and in addition an early ovum. 
The giand on the other side, which was much smaller, showed 
spermatozoa in certain of the tubuli.” In the case of the pheasant 
the piumage was somewhat mixed, but on the left side it was 
roughly that of the adult male; the left leg showed a well marked 
spur; on the right no spur was present. ,,A well developed ovi¬ 
duct is present on the left side, and a sex organ occupies the 
usual situation of the left ovary. Microscopic sections of different 
areas of this giand show that it is an ovi-testis. It consists of 
ovarian elements undergoing pigmentary degeneration and of testi- 
cular elements which show active growth.”
