THE INTESTINAL PROTOZOA OF FROGS AND TOADS. Di 
Cimzenomonas batrachorum Grassi, 1882.1 
Trichomonas batrachorum (Perty) Stein, 1878; S. 
Kent, 1880; Biitschli, 1884; Blochmann, 1884; Doflein, 
1901, etc. 
This animal was first recognisably described and named 
by Perty in 1852. I retain Ehrenberg’s emended spelling of 
TEXT-FIG. 
Trichomonas batrachorum—diagrammatic. n. nucleus; 
b. blepharoplast; fl. flagella; aw. axostyle; cp. its caudal 
process; m. undulating membrane; ce. chromatic edge of 
same; cb. its chromatic basis; es. cytostome. 
the generic name introduced by Donné (Tricomonas, 1837, 
for T. vaginalis). 
The occurrence of the parasite differs somewhat from that 
of Trichomastix. It is found not only in Rana tempor- 
1 Grassi here gives the following synonyms: “ Cercomonas in- 
testinalis ? Ehrbg.,” “C.ranarum ? Ehrbg.,” Bodo intestinalis 
? Khrbg., and Bodo ranarum ? Ehrbg. The first pair are really 
synonyms for the second pair. (Cercomonas = Dujardin 1841, used 
to replace Bodo Ehrbg. by Perty 1852.) Bodo intestinalis Ehrbg. 
is probably Octomitus (see further on under this heading).
