SPOROZOA. 



liberated in the lumen of the organ. The centrally situated 

 single nucleus grows and undergoes division, and the many 

 nuclei become arranged round the periphery of the cyst. 

 Finally projections representing the extremities of marginally 

 situated spores appear to radiate round the periphery of the 

 spherical body. In a freshly ruptured cyst twenty or more 

 spores are seen lying parallel to one another. Spores are 

 elongate, spiadle-shaped, and sHghtly curved, one end being 

 more finely pointed than the other. The nucleus is oval, 

 vesicular, and situated near the rounded end of the spore. 

 In the centre of the spore is a round chromatin mass which 

 stains intensely, and minute granules of chromatin are also 

 irregularly distributed on both sides of the nucleus.

Dimensions. — Cysts measure 60-90 /x in diameter ; spores 

 are 13/Lt by 2-2-5 fi, the nucleus measuring 3-25 ^u, by 2-25 //,. 



Remarks. — ^The parasite was examined in the dried faeces of 

 a cow, and it is not certain if the form is morphologically 

 distinct from G. besnoiti of the cattle and G. faurei {G. gilruthi) 

 of the sheep and goats.

Remarks. — Gilruth and Bull (1912) recorded the infection 

 in the kangaroo, wallaby, and wombat in Austraha. Knowles 

 (1928) mentions that Acton observed a case of infection in 

 a wallaby in the Zoological Gardens, Alipore, Calcutta, but 

 a description does not appear to have been pubhshed. 



Habitat. — Alimentary canal of a wallaby : Bengal, Calcutta.
