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. vergl. 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 tuber 
part of the oviduct. My first thought was that these structures might 
represent aborted follicles of a left ovary, otherwise completel disappéå 
red. If this should prove to be confirmed, an original true hermaphrodit!C 
condition evidently had turned into a merely pseudohermaphroditic one: 
But microscopical examination of the vesicles in toto as well as of ser 
sections, after imbedding in paraffine, failed to show any sexual cells at 
all; these vesicles appeared to be simply pathological structures.
