Viruses of the Tj-pical Pox-Disease Group, inducing diseases characterized by forma- 

 tion of papules, pustules, and scabs, shed with or without scarring. Generic name 

 from Barrel, investigator who first discovered the specific granules of fowl pox and 

 Latinized name of the smallest Greek letter, iota, signifying smallest particle. The 

 name Cytoryctes variolae Guarnieri 1892 was based on intracellular inclusions, Guar- 

 nieri bodies, as supposed sporozoan parasites (Calkins, Jour. Med. Res., 11, 1904, 

 136-172). 



The type species is Borreliota avium Goodpasture.
