They are usually oval, sometimes round, in shape and measure about 
12 to IQ jjb in length and 5 to 8 yu, in breadth. The protoplasm stains 
a blue colour with Giemsa. They contain a varying number of nuclei. 
In some there are two or three large round nuclei and four to six small 
round granules, in others there are five or six large round nuclei and 
two or three small red stained granules, whilst in a few there is only one 
large pale nucleus. To my mind a few look somewhat like leucocytes 
which are undergoing pycnotic degeiieration, whilst others suggest the 
appearance of haeinogregarines. 
I have as far as I can remember only met with them in the mole, 
and in the blood of rat which contained definite haemogregariues. 
Elleipsisoma thomsoni. 
These parasites, discovered by Thomson and named by Franca, 
I occasionally found in the blood of the mole. In some cases they were 
associated with Grahainella and in others with T. talpae, often with 
neither. The adult bodies are round or oval measuring about 10/r. 
by ofu.. 
The protoplasm in my experience stains a very pale blue, or even 
a reddish, colour with Giemsa, and in some cases contains granules 
scattered irregularly throughout its substance. The nucleus varies 
considerably in size and shape. In some it is diffuse, stains lightly, 
and occupies about one half of the whole parasite; in other cases it is 
compact, more deeply stained and measures about 3 to 4 ya in diameter. 
In all cases the nucleus is situated at the margin of the body. The 
parasite contains no pigment. 
I have sometimes found a few free vermiform bodies with small 
oval nuclei. 
Micro-filariae. 
Embryo Filaria in the Mole. 
In the peripheral blood of a mole 1 found one embryo Filaria 
having the following characters. 
It was almost straight, earth-worm like in shape, with the anterior 
end rounded. For nearly its whole length it had the same dimensions, 
and ended somewhat abruptly in a pointed tail. I do not think it 
230ssessed a sheath, although at the anterior and posterior ends it \vas 
devoid of nuclei.
