48 ON THE DEVELOPMENTAL HISTORY OF THE MOLLUSCA. 
Fig. 22. Ovarian egg of Loligo, showing peduncle, capsular plications, and germinal 
vesicle. Drawn from a specimen examined in the fresh state. 
Fig. 23. Portion of a similar section to that drawn in fig. 10, Plate 11, but more highly 
magnified (Harrnack’s No. 10 & immersion) in order to show the relation 
of blood-vessels to the folds of the inner capsular membrane, and the passage 
of cells Jodily from the proliferous ridges into the yelk of the growing egg. 
Fig. 24. Portion of the surface of a fresh egg of Sepia, after escape from the ovarian 
capsule (7. ¢. uterine), showing modified cellular elements. 
Fig. 25. Modified cells (derived from the inner capsular epithelium) observed beneath 
the denser cortical substance of a fully formed or uterine egg of Sepia. 
Fig. 26. Modified cells from a not fully formed ovarian egg of Sepia. 
Fig. 27. Portion of the egg and capsule drawn in fig. 9, Plate 11, to show more fully 
the condition of the inner capsular epithelium. 
The egg is not fully grown, and the process of proliferation from and 
absorption of the inner capsular ridges is not established as in the egg of 
fig.23; but the cells have the character of those found on thickly secreting 
mucous surfaces, and some appear as goblet cells. 
bv. Blood-vessel. 
oc. Outer capsular membrane. 
ic. Inner capsular membrane. 
Fig. 28. More highly magnified view of goblet cells (cc) and simple connective-tissue 
corpuscles (4b) from a portion of the same section.
