Haroeirr: Pennaria tiarella and Tubularia crocea. 
PLATE 5. 
Tubularia crocea. 
All eggs killed in corrosive-acetic. All Figures < 1600. 
Fig. 30. Odcyte before growth; chromatin has begun to form a thread. 
1 Tron hematoxylin. 
Fics. 31-33. Odcytes in synapsis stage; loops of spireme in a polar arrange- 
ment. Iron hematoxylin. 
Fig. 34. Two odcytes; a, odcyte not growing, with chromatin in scattered 
masses; b, odcyte with loops still present but becoming granular; 
polar arrangement lost. Iron hematoxylin and Congo red. 
Fias. 35-37. Odcytes at the start of the growth period. Spireme of nucleus 
has lost its polar arrangement. Iron hematoxylin. 
Fic. 38. Odcyte at the beginning of growth, with the chromatin in delicate 
granular strands. The double appearance of the threads may be 
accidental. Iron hematoxylin. 
Fics. 39-47. Germinative vesicles of growing odcytes of various ages show- 
ing stages in the disappearance of the nucleolus. 
Fras. 39, 40. Substance has left the nucleolus and is collected in several 
places in the nuclear reticulum. In Figure 40, a is the nucleus 
of an odcyte which would probably have served as food; nucleolus 
larger than that of the growing egg, b. Picro-hematoxylin. 
Fig. 41. Nucleolar fragments in nuclear reticulum. Ehrlich’s hematoxylin 
and eosin. 
Fig. 42. Odcyte about one-quarter of its mature size; nucleolus in several 
pieces. Picro-hematoxylin. . 
Fic. 43. Odcyte about half grown; nucleolus in several pieces. Ehrlich’s 
hematoxylin and eosin. 
Fic. 44. Odcyte nearly full grown (entire egg shown in Figure 56), nucleolus 
in one large vacuolated, and several smaller fragments. Ehrlich’s 
hematoxylin and eosin.
