Remarhs. — Patton (1908) merely recorded this as a new 

 species, without giving any description. It is, therefore, not 

 certain that this is morphologically distinct from H. canis. 



Habitat. — Leucocj^es of the cat, Felis sp. : India. 



87. Hepatozoon funambuli (Patton). (Fig. 68.)

The gametocyte has an elongate oval body, with one end 

 larger and rounder than the other. It lies in the large mono- 

 nuclear leucocyte, and shows slow vermicular movements. 

 The narrow end shows a distinct bend upwards, simulating 

 a tail. In escaping from the host-cell the more rounded 

 end protrudes first. The free vermicules are elongated and 

 spindle-shaped ; they are very active, performing rapid 

 serpentine movements, twisting and curling about. In 

 preparations stained with Romanowsky's stain cytoplasm 

 stains light blue, somewhat darker at the two ends. There is 

 no capsule round the parasite, but by prolonged staining a faint 

 pink outline is seen round it. Nucleus large, irregularly 

 quadrilateral, lying about the centre, staining more deeply 

 but not uniformly. A number of large chromatic dots are 

 seen in the cytoplasm, more in one extremity than in the other. 

 Sometimes two parasites are seen in the same leucocyte, 

 lying close to each other, between the two detached parts of 

 the nucleus, or one on either side of the nucleus. The free 

 vermicule contains a rounded or oval nucleus. 



Dimensions. — Intracorpuscular forms 10 /x by 5jU. in the 

 widest part ; free vermicules 13-14 /x by 3-4 /x. 



Remarks. — The parasites were present in the peripheral 

 blood and in smears from the spleen and Hver. Vermicules 

 were also seen from the mid-gut and the body- cavity of the 

 louse, Hsematopinus, but no developmental forms were met 

 with.
