as up to the present no very detailed account lias appeared 
of these forms. 
During the summer of 1910 I was able, while occupying 
the British Association table at Naples, to obtain a number 
of Box boops, the stomachs of which were heavily infected 
with a flagellate which I must regard as identical with the 
form described by Leger as Try pa noplasm a intesti- 
nalis . 
The most interesting point, however, in connection with 
my material, is that in life this parasite seemed to me always 
to possess three anterior flagella, though in stained forms 
they were not usually easy to unravel. For this reason I 
have decided to re-name this form Trypanoplasmoides 
i ntestinalis. I also found the curious form which Leger 
was inclined to describe as a female Trypanoplasma, and 
which Alexeieff has more recently described under the name 
of I’richornonas Legeri. I am inclined to regard this 
form, for reasons which I hope to give in a later paper, as the 
zygote of Trypanoplasmoides intestinalis. 
My opportunity of working on the parasite in the stomach 
of Cyclopterus lumpus arose during a stay at the Scottish 
Fishery Laboratory at Aberdeen, and I should like to take 
this opportunity of thanking Dr. Williamson for his ever- 
ready help in connection with this part of the work. 
In this case, again, I am not inclined to regard this 
parasite as a true Trypanoplasma, and for the reasons given 
below I have decided to retain for this animal Apstein’s name 
of Heteromita dahlii. 
I have not succeeded in finding any very important stages 
in the life-cycle of Trypanoplasma congri, but I have 
decided to publish here a short account of some curious 
rounding-up stages, and also of some abnormal division forms. 
In a future paper I hope to return to some interesting stages 
of the parasite in Cyclopterus as well as the forms which 
I regard as the zygote of Trypanoplasmoides intesti- 
nalis. 
I should like to take this opportunity of thanking the staff
