not contain a granule of chromatin. The mass of chromatin divides 
into two, and the cytoplasm may or may not divide synchronously. 
In cases where the cytoplasm does not divide synchronously, the 
chromatin goes on dividing until there are from io to 16 masses of 
chromatin (Plate XXIX, figs. 78-80) arranged almost around the edge 
of the cell. These rosettes later show divisions into young parasites 
(Plate XXIX. fig. 79). Rosettes were seen leaving the host-cell, and 
also found free in the serum (Plate XXVIII, fig. G6). In one slide a 
group of eleven young drepanidia that had just escaped from the 
rosette condition was seen (Plate XXVIII, fig. 72). These forms were 
77long and ri/x wide. Their cytoplasm was of a faint-staining, 
coarse, granular structure. The nucleus was composed of a larger, 
central mass of granules and, usually, a chromatin granule on either 
side; occasionally both were on one side. In one case the chromatin 
seemed to be dividing (Plate XXVIII, fig. 72). These sporulating* 
forms always arose from the “slender” drepanidia. In one series of 
eight slides from one frog many sporulating and “slender” forms 
were seen, but none of the larger drepanidia described in the next 
paragraph. 
In a few frogs, liana mascariensis , a very large drepanidium was 
seen, which was like the common form, but larger. It was lighter 
stained and often took a pink colour instead of the normal blue. The 
cytoplasm was coarsely granular, and many of the parasites had 
non-staining, highly-refractile globules in them. These globules were 
from one to one hundred in number, and from cr6/i to 77/1 
diameter. They were always found near the nucleus and gave the 
appearance of a fatty degeneration of the nucleus. They sometimes 
distended the drepanidium until it was nearly round (Plate XXIX, 
%• 89), but they usually did not affect the size of the parasite. The 
large type of drepanidia presented three forms, a long form, a short or 
young fonn, and a folded or “ two-shanked ” form. I he long form 
'Plate XXIX, fig. 86) was usually 22-6// long and 7/t wide. The 
nucleus was 3-4/* long and 5-6/1 from the posterior extremity and 
T^/i from the anterior extremity. 
The short, or young form (Plate XXIX, fig. 83) was about 8'8/i long 
and 6'6/t wide. The nucleus was 4 ‘ 4 / / ' n diameter and placed in the 
centre of the organism. 
The folded form was seen in the various stages of unfolding 
( p l«e XXIX, figs. 87, 88). _
