he places near Cercomonas. B. intestinalis 1838 can not, of course, 

 be taken as type of Bodo 1832. 



Biitschli (1884) states that there are five or six species in this 

 genus; he figures three species, none of them Ehrenberg's originals, 

 and fails to designate a type. Ludwig (1886) mentions only Bodo 

 caudatus (Dujardin), but this is not an original species, hence can not 

 hold as type. 



Under these circumstances, especially since I can not obtain 

 Gleichen's reference to Monas punctum^ the determination of the 

 type is attended with uncertainly. If Monas 'punctum is identical with 

 Bodo saltans, I should be inclined to take that as type, especially in 

 view of Stein's (1878) work. 



Cercomonas Dujardin, 1841. Nine original species. No author 

 appears to have designated a type until Kent (1880) proposed C. tij- 

 picus, 1880, as such. This designation is clearly inadmissible, as 

 Kent's species was not contained in the original genus. From the 

 work of Stein (1878) and Biitschli (1884) it is probable that either 

 C. longicauda or C. crassicauda should serve as type. Possibly 

 Lud wig's (1886) work could be interpreted as a selection of C. 

 crassicauda. 



Ciliaris Salisbury, 1868. Only original, hence type, species, C. 

 hicaudalis. 



Costia Leclerq, 1890. Only original, hence type, species, C. necator 

 (Henneguy). 



Cryptohia Leidy, 1846. Only original, hence type, species, C. 

 helicis. 



Cryptoicus Leidy, 1847. Cryptohia, 1846, renamed, hence takes 

 same type as Cryptohia. 



Cystomonas R. Blanchard, 1885. Type species, ''Bodo urinarius 

 Künstler, 1893". 



Dimorpha Senn, 1901 [not Jur., 1807, hymenopteron; not Gray, 

 1840, mollusk; notHodgs., 1841, bird]. Y ox Dimorphus Gxdi^&i, hence, 

 type, DimorpJms muris. 



Haematomonas Mitrophanow, 1883. Two original species. H. co- 

 hitis here designated as type. 



Hemotomonas Blanchard, 1888, for Haematomonas. TT co type 

 species, Haematomonas cohitis. 



Herpetomonas Kent, 1880. H. muscae-domesticae (Stein, 1878) 

 designated by Kent as type. 



Hexamita Dujardin, 1841, Three original species. Type, H. 

 infiata.
