immediately after the telophase of the second meitotic division 
and bear a remarkable resemblance to the interkinetic spermato- 
cytes, except that they are smaller and that their chromosomes 
soon break up into granules. 
7. DISCUSSION 
The author believes the female diploid number of chromosomes 
of Anisolabis to be twenty-six in both germ cells and soma 
cells, as against twenty-four claimed by Randolph (’08) for both 
sexes. The normal male diploid number is twenty-five although 
somatic mitoses with twenty-four chromosomes are found. 
The union of the two x-chromosomes into a single body is 
probably the explanation of this last phenomenon, and this 
supposition is strengthened by the fact that, in the growth of 
the spermatocytes and in the first spermatocyte division, these 
two x-elements of the xxy-hexad are in close apposition, leading 
to the assumption that the two parts are intimately related. 
The x-complex may be considered either as having originated 
from a single x-chromosome or as now being in the process of 
the formation of a single x-chromosome out of two previously 
distinct chromatic elements. 
Another view of the 24 chromosome somatic male cells is 
possible: namely, that after a number of somatic divisions, the 
y-element undergoes a dissolution. From the behavior of the 
y-element in the growth of the spermatocytes, one may infer 
that it is greatly different from the normal chromosomes; for, 
not until the late strepsistene does it acquire a true chromatic 
stain, when tested with alizarin crystal violet or with methyl 
green +acid fuchsin. Only after giving off the nucleolar spherule, 
which takes the mitochondrial stains deeply, does its definite 
chromatic nature appear. 
Our interest in the y-chromosome must be again kindled in 
view of the recent type of inheritance described by Castle 
(’21) linked with this exclusively paternal chromatic element. 
We must try to determine whether the y-chromosome is a chromo- 
some in a state of formation or whether it is merely a degenerate 
x-chromosome.
