ART. 23 A NEW SPECIES OF PEOTOZOAN — ZELIFF 6 



Table 1 lists the species of Nyctotherus that have been recorded, 

 but the complete data on each are difficult to obtain. The letter C 

 indicates the presence of a caryophore. Bhatia and Gulati (1927) 

 give a list of species and a key for identification. The list is included 

 here with some additions, but the key is not repeated. A^. osmodermae 

 is closely related to A^. duboisii (Kiinstler).
