Among the types regularly dissected by University students of 
Natural History in my zootomical courses pigeons always form a 
part. Some years ago were found, at different times, the two cases 
now to be described The pigeons had been bought among a good 
many others from some dealer in ’poultry, and as they were wholly 
or partly plucked before their entrails were going to be examined, 
it was not possible to settie if any noticeable peculiarities had been 
apparent in their piumage. Both are male specimens, young, but 
full-grown; with the neck completely extended they measure from 
the top of the head to the end of the rump: A 20 cm, B 21 cm. 
A (Fig. 1) shows two, in all essentials, normally looking testes, 
excepting only that the right one is considerably smaller than the 
left. The left testis is almost ovoid, 14 mm long, 6 mm where 
broadest; the right testis is more pyriform, somewhat pointed to- 
wards the posterior end, 10 mm long, 4,5 mm where broadest. 
The epididymis and the vas deferens of both sides are developed 
normally and correspondingly to the age of the specimen; the se- 
minal duets open as usual at the tip of distinetly formed genital 
papillæ, and medially between the latter the two urinary openings 
are seen. Thus the entire male apparatus must be said to be in 
the main normal, the considerably lesser size of the right testis 
hardly being a very rare phenomenon in the domestic pigeon. 
But in addition to the male apparatus a distinet oviduct is 
found on the left side. This oviduct quite resembles that of a 
female pigeon of corresponding age, i. e. that of a normal young 
female, which never yet has laid any eggs. It is ca. 40 mm long, 
in the middle ca. 2 mm broad, ribbon-shaped, almost straight, only
