uteri they are all in the prophase of the first maturation division, 
and in the uteri the small spindle is found near the centre of the 
egg; apparently the first pole body is not cut off until the ova have 
passed out of the body. The details of the maturation are reserved 
for a separate paper; here it may simply be noted that during the 
first maturation mitosis the achromatic spindle is very small, much as 
in Ascaris megalocephala, and the number of the minute chromosomes 
apparently seven; and during this maturation the yolk becomes much 
more finely subdivided and regularly distributed throughout the cell. 
In the adult condition all the ovarian ova are of the same de- 
finitive size.. 
Literature on the female genital organs. Here it is 
not necessary to consider all the anatomical differences of detail de- 
scribed by the different authors, for considerable differences, parti- 
cularly in the cloacal region, are found in the different genera. Hence 
we may consider mainly that literature describing the ovaries, and the 
different terminologies; here it may simply be mentioned that no writer 
has noticed the ciliation of the oviducts. 
VEJDOVSKY (1886) distinguishes as “Kierstécke” the segmentally 
arranged proliferating points of the ova, and he is the first to call 
attention to this segmentation; these he observed on females at the 
end of oviposition. From these “Eierstôcke” the ova detach them- 
selves and fall into the spaces, “Eiersäcke”, which he regards as 
coelomic cavities; these, when filled with ova, are what the preceding 
authors had described as “Eierstöcke” or “Ovaries”, and the ova in 
them are represented as not surrounded by the germinal epithelium. 
“Es existirt später keine Leibeshöhle mehr, indem sie eigentlich von 
den Eiersäcken eingenommen wird.” He describes then the “Ei- 
behälter”, regards then as produced by splitting of the mesenteries, 
and as lined simply by parenchym. The posterior ends of the “Ei- 
behälter” are called “Eileiter”. In his next paper (1888) VEIDOVSkY 
described the young “Eierstöcke”, first finger-shaped, later lobular 
cell outgrowths from the wall of the mesentery, each “Eierstock” lined 
by the germinal epithelium; “nach den gegenwärtigen Beobachtungen 
gelangen die Eier aus den Ovarien direct in die Eibehälter, und erst 
die später sich entwickelnden Elemente fallen, aus Mangel an ge- 
nügendem Raum in den Eierstockslappen, in die.Leibeshöhle”. He 
notes that the ova in the body cavity show nuclei, those in the “Ei- 
behälter” do not; evidently the latter are then in the maturation
