Fig.50.—Salamandra maculosa, oogonium (primary). Telo- 
phasic ring, about same stage as last, chromosomes more elongated and 
taking on an erratic course. 
Fig.51.—Triton palmatus. Large endothelium nucleus from 
follicle of testis. Late telophase, ring almost closed. Nucleus very flat ; 
almost all the chromosomes drawn ; chromosome axes distinctly doubled 
and entwined. 
Fig. 52.—Do., do., a smaller nucleus, somewhat later stage. 
Fig. 53.—Bombinator igneus. Endothelium nucleus, entire, 
testicular peritoneum. Polar view (not a section) of telophase of same 
stage as last. All the chromosomes have been drawn, though not through- 
out all their length. 
Fig. 54H 0 mo. Endothelium of vein of cutis. Section of telophase, 
about the stage of fig. 51 or 53. 
Fig.55.—Triton palmatus, Spermatogonium, early interphase. 
Fig. 56.—Do. Late interphase, or dawn of spireme. 
Fig. 57.—Do., do. Early spireme. Karyoplasm browned by osmium, 
Fig.58.—Bombinator igneus. Peritoneal endothelium. Early 
rest stage. 
Fig. 59.—Do., do. Later rest stage. 
Fig. 60.—Oedipoda cothurna. Spermatogonium. One half ofan 
equatorial figure. Chromosomes all of them as tightly-folded V’s. 
Fig. 61.—Do., do. Sagittal section of anaphase. Chromosomes so 
tightly folded that they appear as stout curved staves. 
Fig. 62.—Do., do. Early telophase, tangential section of ring. Shows 
three hyaline globules (to the right). 
Fig. 63.—Decticus verrucivorus. Spermatogonium. Equa- 
torial figure. All the chromosomes drawn. All are tightly folded into the 
stave shape ; m is the monosome. 
Fig. 64.—Do., do, anaphase, polar view. Chromosomes folded into the 
shape of wedges ; m, monosome. 
Fig. 65.—Do., do. End of anaphase. Chromosomes as before. 
Fig. 66.—Do. Primary spermatogonium. Mid-telophase: m, the 
monosome. Some of the chromosomes seem to have their moieties divari- 
cated at bot h ends, asif a transverse segmentation had taken place at the 
polar ends. 
Fig. 67.—Do. Nucleus of connective tissue enclosing cyst of testis. Karly 
telophase,
