is enelosed has a great number of leaflike protuberances. It seems 
to me probable that the two glands are testes and. that the mush- 
room-like organ performs the office of a penis, but to make this 
matter clear, living speeimens are of course necessary”. 
He finally describes the two calcareous penes, which KorEx and 
DANIELSSEn were shortly after the first to interpret as such. 
v. GRAFF, in his paper on Neomenia (6) hardly touches on the 
genital system: he confirms the view enunciated by TULLBERG, in 
looking upon the „lateral glands” as testes. 
Kor£n and DAnIELSssEn (16) give the following account of the 
genital apparatus of Neomenia : 
„Along the dorsal surface of the animal, in the same direction 
as the keel, and between the latter and the stomach , lies the herm- 
aphrodite gland, which is lobate, consists of a number of acini, 
and has in the middle a tolerably wide efferent duct. When this 
has come a little way out of the gland it divides into oviduct and 
vas deferens. Into the oviduct open the efferent ducts of the alb- 
umen gland which is three-lobed and oblong. As regards the vas 
deferens, we have reason to think that it divides, but cannot state 
anything with certainty upon this point; for we have seen the con- 
nection between the vas deferens and the penis-sheath only on one 
side, without being able to observe any division. On each side of 
the vestibulum there opens in its lateral margin a penis-sheath 
which is extraordinarily muscular and is clothed inside with eylin- 
der epithelium. Each of these sheaths encloses a compressed horny 
sheath, which is open along one margin, and at the posterior ex- 
tremity beset with numerous small appendages; within this sheath,, 
again lies the true style (penis), which is likewise compressed, and 
terminates in a sharp point. The vestibulum is tolerably wide, 
with firm walls clothed with eiliated epithelium, and into it besides 
the two penis-sheaths already described there opens a small oblong 
vesicle with a short efferent duct (receptaculum seminis), as well 
as two iooped mucus glands with a common duct. The little 
oblong vesicle was filled with a cream-like fluid !) in which sperm-
