288 A CYTOLOGICAL INVESTIGATION OF SOME SPECIES 
a similar way in each group, which makes it probable that all are deri- 
ved from gemini. One chromosome probably still lies in the aequator, it 
is visible at a lower level than the highest group and is unpaired.

In both groups 45 chromosomes are present, while 1 lags behind, 
pointing to 91 as the diploid number. Even if not all chromosomes of 
the two groups were derived from gemini, one should still have to con- 
clude to this number, as there is no reason to assume that in these 
groups unpaired split chromosomes should already be present, which 
could be the cause of the finding of too high a diploid number.

In fig. 80 also, the corresponding arrangement of the chromosomes 
in both groups, is apparent. In the drawing of the highest group, 4 
chromosomes lying in the aequator are indicated; of the one, lying to
