[ 99 ] CEPHALOPODS OF NORTHEASTERN COAST OF AMERICA. 
tabulated organs, intimately united together and connected with the 
veme cavse, and mostly situated below and in front of the heart, but 
there are two more compact glandular portions (r') extending, as usual, 
backward along each of the posterior venie cavae ( vc ") in the form of a 
tang pyriform gland. Just in front of the bases of the gills, on each 
side, there is a circular opening (u) through the peritoneal membrane, 
which probably gives exit to the urinary excretions. 
The reproductive organs of the female, however, present the greatest 
divergence from Loligo and allied forms. Instead of having a single 
large oviduct on the left side only, and opening far forward, we find in 
this.genus two small oviducts (od), symmetrically placed and opening 
much farther back. The ends are free, near the bases of the gills, but 
behind them, instead of passing over the dorsal sides of the bases of the 
gills, as in Loligo and other genera. The apertures of the oviducts are 
simple elongated slits. Moreover, instead of the large and very con¬ 
spicuous, nidamental glands, situated in front of the heart, as in Loligo , 
we find in Ommastrephes much smaller and simpler glands (.nr), situated 
much farther back, side by side, near the median line, behind the heart. 
The ovary (or) is a tang, pyriform, tabulated organ; its anterior end 
is attached to the posterior end of the stomach, and is divided into sev¬ 
eral short tabes, which clasp the end of the stomach; its small posterior 
end extends backward into the concavity of the hooded portion of the 
pen {p"). 
The spermary or testicle of the male (Plate XIX, fig. 1, t) occu¬ 
pies the same position as the ovary; it is a more compact organ, with a 
smoother surface, and the anterior tabes are longer and narrower and 
extend farther forward along the sides of the stomach. The prostate 
gland and other male organs resemble those of Loligo (see Plate XXIX, 
figs. 1, 2). 
It must be borne in mind, however, that none of the specimens ex¬ 
amined were in their breeding season. Consequently, the reproductive 
organs were all much smaller and less conspicuous than they would 
have been in breeding individuals. This is particularly the case with 
the ovaries and oviducts, but the same remark would also apply to 
the nidamental glands, which might assume a different form, as well as 
much greater volume, at the breeding season. 
The specimens dissected had all been preserved in alcohol, which 
would cause these organs to appear smaller than is natural.
