PLATE 2 



EXPLANATION OF FIGURES 



All figures were taken from the testis of Anolis carolinensis. 



13 and 14 Side views of the first maturation spindle, showing the X-chro- 

 mosome. 



' 15 to 17 Late anaphase stages of the first maturation division. In the case 

 of figure 17, the two plates overlapped, so in order to show each end clearly the 

 slide was moved a trifle after the upper pole was drawn. 



18 Side view of the second maturation spindle, showing the precocious 

 splitting of the chromosomes. 



19 Equatorial plate view of a second spermatocyte cell, showing five large 

 chromosomes. 



20 Equatorial plate view of a second spermatocyte cell, showing five large 

 chromosomes. 



21 Late anaphase of a second spermatocyte cell, showing that five large 

 chromosomes are going to each pole. 



22 and 23 Equatorial plate views of second spermatocyte cells, showing the 

 presence of six large chromosomes. 



24 Late anaphase of a second spermatocyte division, showing six large chro- 

 mosomes going to each pole.
