in the sucker. Seen under the oil-immersion lens the sucker 

 is seen to be surrounded by a clear area, and the surrounding 

 epicytal striations appear to run into each other and interlace. 



The sucker was seen to be retained in the case of one of the 

 gametocytes in a gametocyst.

pointed posteriorly. Epimerite forming a knob-hke structure, 

 with its cytoplasm differentiated from that of the rest of the 

 body. Nucleus large, subspherical, with a single karyosome. 



Dimensions.- — Length of the trophozoite 475 /x, maximum 

 width 94- 5 /x ; epimerite 14ju, in length ; nucleus 38-5 ju, by

Remarks. — The parasite somewhat resembles L. elongata 

 (Mingazzini) in the differentiation of its anterior end, which 

 is described by Mingazzini as a small spherical button, but 

 according to Reichenow (1932) an epimerite is absent, and the
