148 A CYTOLOGICAL INVESTIGATION OF SOME SPECIES 
‘chromosomes. This nucleus contains 5 of them, two lie in the center of 
the figure and are visible when focussing at a high level; at the extreme 
left one sees one of them just above the V-shaped black chromosome- 
pair; at the top of the drawing one is seen to the right of the black loop- 
shaped geminus, while, finally one is situated at the extreme right obli- 
quely above the dark-grey cross-shaped chromosome-pair between two 
other gemini. This latter nucleolus especially is hardly distinguishable 
from a chromosome.

These small nucleoli occur in Fidji sometimes but not always in the 
diakinesis-nuclei, they may also occur in other kinds.
