rounding tissues was cut out just behind the posterior end of the 
visible oviduct. The piece was imbedded and cut in transverse 
sections with a microtome; the microscopical examination settled 
that no trace of an oviduct was contained; thus the oviduct really 
terminates where it seems to terminate. It is flat, ribbon-shaped 
1 mm broad, its muscular wall rather feeble ; its tubar part, situ- 
ated as usual on the cephalic part of the kidney, is strongly folded 
transversely, the ostium turned round, with the slit-like funnel, ca. 
3 mm in length, facing the left testicle. The suspensory ligament of 
the oviduct is narrow; its dorsal part has the same length as the 
oviduct, broadens in front where it is continued into the coating 
of the left testis; the blood-vessels are small and scanty, muscular 
elements hardly visible; the ventral part (vm Fig. 2, II) is propor¬ 
tionally strong, but disappears about at the middle of the oviduct, 
in front as usual splitting into the ostial lips; from the point where 
the latter again are joined the usual ligament (li) passes across 
the kidney to the rib. 
On the right side, 5 mm behind the kidney, a small muscular 
body (od) is found suspended to the right vas deferens by means 
of a mesenteric fold; it is flat, pointed behind, broadening in front 
where it is transversely plicated; its length is about 5 mm, the 
breadth ca. 1,5 mm. Though no ostial aperture can be detected, I 
think this body must be a deformed rudiment of the right oviduct ^). 
In the cloaca no traces of oviduct-openings are found neither on 
the left nor on the right side.“). 
A rudiment of the right oviduct is said not to be rare in the domestic 
pigeon (cfr. f. inst. Vogt and Yung: Lehrb. d. prakt. vergi. Anat., Vol. 
II, 1889-94, p. 196). 
Dorsally to the forepart of the left testis, hidden by the latter, is found 
a small group (0,8 mm in diam.) of a few transparent vesicles (0,3—0,4 
mm in diam.), just in front of the epididymis, and a few similar small 
vesicles are to be seen in the part of the ligament that carries the tubar 
part of the oviduct. My First thought was that these structures might 
represent aborted follicles of a left ovary, otherwise completely disappea- 
red. If this should prove to be conFirmed, an original true hermaphroditic 
condition evidently had turned into a merely pseudohermaphroditic one. 
But microscopical examination of the vesicles in toto as well as of serial 
sections, after imbedding in paraffme, failed to show any sexual cells at 
all; these vesicles appeared to be simply pathological structures.
