oggs have been developed. In two specimens he finds that the egg- 
laminae consist in their exterior portion of a granular substance, 
also cellular, but of an entirely different character from the cells 
just mentioned. To give it in his own words: 
„I have not been able to discover either in what relation the 
granular mass stands to the eggs or by what means the eggs, 
when mature, are discharged from the ovary. It would be natural 
to suppose that they come out into the stomach by breaking through 
the walls of the ovary, and are afterwards discharged through the 
anus, but this would be inconsistent with their appearing in the 
bag behind the rectum. This bag I found, at least in the larger 
specimens, filled with a number of irregular bodies exactly resem- 
bling the more mature eggs in the ovaries, but with their contents 
less transparent and without any distinet nucleus. I cannot con- 
jeeture what else these can be than eggs, though I cannot account 
for their presence in the bag. In this organ are also three singu- 
lar bodies, one above and two below, which in the smaller speeci- 
mens looked like mere elevations on the wall of the musecular coat, 
but in the largest specimen differ considerably, inasmuch as that 
throughout the greater part of their length they are free, and the 
upper one is longitudinally divided by a furrow. The compart- 
ments of the ovary nearest to this bag contain no eggs, but are 
filled with laminae of a yellow shining substance, the nature of 
which I am not at present able to explain. No external limit is 
visible between this part and the rest of the ovary, and the yellow 
shining laminae begin almost immediately where the formation of 
the eggs ceases. Possibly this organ may communicate with the 
two large lateral glands. These two glands of which I did not 
succeed in making entirely uninjured preparations, and to the 
structure of which I have not paid particular attention, I shall 
here only mention in a few words. They show a somewhat large 
lumen in which the inner membrane forms very deep folds. The 
mushroom-shaped organ which contains their common efferent duct 
is, at its free and dilated end provided with a number of conical 
excrescences and the widening of the rectum in which this organ
