38 J. A. Gilriith : Haemoyrcgarinc 



be affected in any way beyond the increase in the size of the 

 nucleus and the occasionally observed increased size of the cell. 



In addition to the intra-corpuscular parasitic bodies a large 

 number of free bodies, broader and shorter than the gregarines 

 (8.4 to 9.8 microns long and 4.5 to 5.6 microns wide) may be 

 seen in the smears. Tlie great majority are slightly ovoid, but 

 some are somewhat curved. Although staining fairly uniformly 

 with the basic blue stain, a number show a double irregular 

 rod-like body centrally situated, lying longitudinally. Similar 

 bodies are not present in the smears from the other Varanus, 

 so while it is possible these may be extra-corpuscular forms of 

 the gregarine, at present one cannot be definite as to their 

 nature. 



As the literature referring to Haemogregarines in other 

 Varanidae is at present inaccessible to me, I refrain from 

 attaching any specific name to the parasite now recorded and 

 described.
