sheep, goats, camels, certain deer, rats (Mits dcciinmiius) 

 and man,' most of them being herbivorous. The adult ( = 

 LiiKjuiituhi serrata) infests the nasal cavities and frontal 



wolf, fox, horse, goat, etc., and rarely, man. The larvae 

 usually occur in the liver, lungs or lymphatic glands of the 

 infected host. 



They may either reach the exterior by way of the trachea 

 or intestines, to be sniffed up by dogs, etc., or they may 

 gain access to their definitive host by the latter eating the 

 infected organs of the intermediate host, It may be 

 remarked that when human beings have been parasitised 

 oy the larval form, its presence had not been suspected 

 until post-mortem examinations revealed the fact. In man 

 the liver seems to be the more common location, whilst in 

 cattle the mesenteric glands are said to be the more fre- 

 quent habitat. Braun,' Railliet, as well as some of the 

 other writers referred to, give details as to the occurrence 

 of the parasite in its larval and adult stages, in human 

 beings. 



The occurrence of the pentastome in our cattle presup- 

 poses the existence of its adult stage in our dogs, and also 

 suggests the possibility of human beings becoming infected.
