326 THE DOLABELLINAE. 
2. Small hermaphroditic duct. 
3. Adnexed genital complex, consisting of the nidamental and albumen 
glands, the fertilization-chamber, and the convoluted and spiral portions of the 
genital duct. 
4. Spermatocyst and duct of Cuvier. 
5. Large hermaphroditic duct, made up of the ovospermatic and the 
copulatory ducts. 
6. Spermatotheca and its duct. 
7. External spermatic groove. 
8. Penis and its sheath. 
Ovotestis.— The ovotestis occupies the posterior end of the body-cavity, — 
in close contact with the liver in front and the body-walls elsewhere. In con- 
sequence its anterior face is irregularly faceted from the pressure of the liver 
and of the loops of the small hermaphroditie duct and the adnexed genital com- 
plex. The remainder of its surface is convex, conforming with the contour of 
the body-walls, its general form being nearly hemispherical. Its extreme 
antero-posterior length is ca. 23.0 mm., its diameter 35.0 mm. The yellowish — 
gray color of the ovotestis contrasts strongly with the uniform black of the 
liver in contact with it. 
Plate 5, fig. 4 represents the main portions of the reproductive apparatus, 
as seen from below, that view revealing the relations of its parts best, with but — 
a minimum amount of displacement. The ovotestis and the penis are not 
shown in this figure. 
Small hermaphroditic duct.— From the upper right surface of the ovotestis 
the yellowish white small hermaphroditic duct (Plate 5, fig. 4, sm. h.d.), arises, 
the loops of its many closely coiled windings resting upon the upper anterior — 
surface of the gland. The approximate length of the duct is at least 65.0 mm., 
though its hardened condition made the measurement difficult. Its diameter 
averages about 3.0 mm. The general course of the duct is obliquely forward 
and to the right, joining the very large adnexed genital complex at its right 
posterior angle. 
Adnexed genital mass.— The dark yellowish brown adnexed genital mass 
(Plate 5, fig. 4, a. g. m.) is strikingly large, nearly reaching the bulk of the ovo- 
testis. In form it is irregularly prismatic, flattened somewhat dorso-ventrally 
and elongated laterally. It is placed transversely in the posterior dorsal region 
of the body-cavity, its thicker portion at the left, resting in a deep groove upon 
the postero-dorsal surface of the liver, and between it and the ovotestis, and is 
closely bound to the dorsal body-wall by connective-tissue.
