    \ Pig. 107.—Flagellates iQ Intestine of Biffo TcgJllaris a-f.—TrichoJUonas hatechornm g-n.—Octomittis {Hexaviitus) dnjardini Ciliates Nyciotherus cordiformis and a Balantidium are both common, but instead of Opalina we have another organism something of the same class though it differs in its nuclear arrangement. The largest specimens of this are about 80/x by 60^, while the smallest are A. C. Stevenson X 450 diam. ]?ig. lOS.—Unnamed organism in Bufo 7-eg7liaris (Kbaitoum Toad} about 60ju by 16^. They are covered by cilia of a uniform length, have no apparatus for ingestion or egestion, and the nucleus usually consists of two pear-shaped bodies connected by a definite narrow strand (Fig. 108). Up to the present I have not identified this. It is characterised by having a definite spine at one end, especially in the smallest and middle-sized forms. I cannot conclude without expressing my deep thanks for the help and kindness I received from Dr. Balfour, Mr. Currie, and any official of the Sudan Government, from the Sirdar downwards, with whom I came in contact.
