on from the first spermatocyte. This fusion is the result of 

 poor fixation, which made the spermatogonia! division un- 

 workable.

THE FEMALE CHROMOSOME COMPLEX 



A study was made of the ovarian tissue of both Anolis caro- 

 linensis and Sceloporus spinosus, with a view of determining the 

 chromosome complex of the females of these two species. Very 

 small young females were used, the ovaries being preserved and 

 sectioned. As was to be expected, no oogonial divisions were 

 found, but scattered here and there among the nurse cells were 

 dividing cells. A great number of these were carefully studied, 

 but most of the equatorial plates were too crowded to allow 

 more than approximate counts. Here and there, especially 

 in cells which had been cut in two by the sectioning razor, the 

 chromosomes lay fairly well apart, so that counts could be made.
