8. S. aramidis Splendore, 1907. — Parasite in Aramidis saracura, a Brazilian 

 bird. 



9. S. ammodromi Splendore, 1907. — Miescheria ammodromi S-plendore, 1907. 

 Mesnil says it is not generic, and perhaps not specific. It is found in a 

 Brazilian bird, Ammodvomus manimbe. 



10. S. leporum Crawley, 191 4, in American rabbits. 



11. 5. setophaga Crawley, 1914, in American redstarts. 



12. S. muris Blanch ard, in rats. 



2. Rhinosporidiidae Poche, 1913. 



Definition. — -Sarcosporidia found in connective tissue and not 

 divided into chambers by septa. 



Rhinosporidium Minchin and Fantham, 1905. 



Definition. — Rhinosporidiidae with well-defined sporoblast. 

 Type Species. — Rhinosporidium seeberi (Wernicke, 1900). 



Rhinosporidium seeberi Wernicke, 1900. 



Synonym. — ■Rhinosporidium kinealyi Minchin and Fantham, 1905. 



Rhinosporidium was discovered in 1896 by Dr. Guillemio Seeber 

 in Buenos Ayres in a nasal polypi in a younglman of tnineteen years 

 of age. In 1900 he published a description of the parasite, and in 

 the same year Wernicke gave it the name of Coccidium seeberi. 



Kinealy, in 1903, reported to the 

 Laryngological Society a peculiar 

 case of polypus growing from the 

 septum of the nose of an Indian in 

 Calcutta as a pedunculated vascular 

 growth resembling a raspberry in 

 appearance by having whitish spots 

 on the general red surface. On 

 section, this tumour was found to 

 have peculiar bodies embedded in it. 



It was then carefully examined 

 and described by Minchin and Fan- 

 tham, who came to the conclusion 

 that it was a haplosporidian, and 

 named it Rhinosporidium kinealyi. 



In 1905 Nair of Madras came 

 across a similar polypus in several people who all came from the 

 small native State of Cochin on the west coast of India. These 

 polypi have been carefully described by Beattie in 1906. Castellani 

 and Chalmers have found it in polypi in Ceylon. 



Morphology. — ^On cutting into the polypus it is noticed that there 

 are minute dots visible to the naked eye, and capable of being dis- 

 sected out. These dots are cysts. 



When examined with the microscope, it is seen that the growth 

 is covered by stratified pavement epithelium, which shows signs of 

 proliferation and invasion by polymorphonuclear leucocytes. Under 

 this epithelium there is a stroma formed of delicate fibrous tissue,
