INTESTINAL TRYPANOPLASMAS OF FISHES.

a true Trypanoplasma. He also drew attention to the pre- 
sence of a form with three flagella characterised by very 
curious movements which he was inclined to regard as a 
female Trypanoplasma. 
During the month of July^ in 1910, I had the opportunity 
during a stay at Naples of examining nine individuals of 
Box-boops, all of which were heavily infected with this 
flagellate. I was immediately struck, in the examination of 
the live individuals, by the fact that all of them when care- 
fully examined showed the presence of three free anterior 
flagella. After the publication of Alexeieff’s note I re- 
examined my stained preparations and found that it was 
extraordinarily difficult to show the presence of these flagella 
on the stained forms. During May of 1912 I examined 
thirteen Box-boops, and again convinced myself of the 
existence of these three anterior flagella in living forms of 
this animal. Upon this occasion I also met with the large 
amoeboid form which Alexeieff has called Trichomonas 
Legeri . I have found some evidence which I hope to publish 
in a later note pointing to the fact that this form is really the 
zygote of Try panoplasmoides intestinalis. In a more 
recent paper, Sur la revision du genre Bodo Ehrhg.^'’ Arch, 
fur Protistenkunde,^ Bd. xxvi, 1912), Alexeieff has re-named 
the normal form of this flagellate Cryptobia intestinalis. 
Taking into consideration the relations of the flagella in this 
form, I have decided to re-name the animal Try pano- 
plasmoides intestinalis. 
In life Trypanoplasmoides is a roughly carrot-shaped 
organism with a rather blunt anterior end, from which three 
free flagella take their origin, while a fourth flagellum turns 
back along the body in connection with the undulating 
membrane to end freely at the posterior end. The three 
anterior free flagella are relatively easily seen in living forms, 
but in stained forms they are usually very difficult to make 
out, as they are very fine and are generally twisted together 
in a single strand. The animals in life move in rather a 
hesitating manner, in a way that is far more suggestive of a
