104 AUSTRALIAN FRESHWATER FLAGELLATES, 



Fara. BODONACEAE. 



Genus Bo do Ehr. 

 BODO EDAx Ivlebs. (PI. i.. %. 10). 



Flag-ellateiistudien, Zeitschv. f. wiss. Zool., Bd. Iv., 1892. Cf. Senn, 

 J.C., p. 135, f. 90a. Oval, more or less flattened on one side, pointed in front, 

 rounded behind, with two distinct flagella near the anterior end, one at least, 

 it' not both, often directed })ackwards. A larjje eoloured food ball often notice- 

 able towards the hinder end. Contractile vesicle in front. 



Long. 15. lat. 10^. Lismore. Rare. 



BoDO SALTANS Elir. (PI. i.. fi;;'. 11). 



Cf. Stein, T. ii., Abt. vi., f. 1 — 7 and Abt. v., f. 15; Kent (Diplom^istix) 

 PI. xxiv., f. 11 — 12 ; Forbes and Richardson, Biol. Upper Illinois River. PI. 

 Ixsxiii., f. 9 (after Kolkwitz). These authorities all agree in identifying this 

 species with the minute drop-sliaped flagellate which is commonly seen under 

 the microscope peeking away at any dissolving mass of protoplasm. The body 

 is slightly curved, broadly rounded behind and somewhat pointed in front. Here 

 are attached two, long, distinct flagella which are turned backwards under the 

 animalcule. Occasionally it fastens itself to some rotting organism by its 

 ipointed anterior extremity, holding on, no doubt, by the ba.ses of the flagella. 

 Cf. Stein, T. ii., Abt. v.. f. 12 and f. 15, in which state it has been described a;* 

 Culpodella pugiiax Cienkowski. 



The figure of Bodo saltans given by Senn, I.e., p. 135, fig. 90ii. would seem 

 to belong to Bodn caudatus (Duj.) Stein, I.e., T. ii., Abt. v., f. 1 — 14 {Am- 

 pliimona.t caitdata Duj. I.e., PI. 7, fig. i.; Diplomasti.r caudata (Duj.) Kent. 

 I.C., PI. xxiv., f. 1—10; lleteriinfita putrina Stokes, Frw. Tnfus. IT.S.. p. 105, PI. 

 ii., fig. 6, 7.) 



Other figures that seem to represent tliis organism are Ile'f'.romifa ros- 

 trata Kent, PI. xv., fig. 18—28, II. uticinata Kent, PI. xv., fig. 29, and H. 

 adunca Meresch. in Kent. PI. xv.. f. 44. 



Fam. AMPHIMONADACEAE. 



Genus R H T p I ii o n e x d r o x Steii\. 



RHIPIDODEXDRON llUXLEVl Kent. (Tcxt-fig. U»). 



Not uncommon in bottom saraiiies from swam[)y ))ools. The eh'gant pale 

 yellow tronds of the cf)enobium attain to about 250ju, in lengtli. The animalcules 

 themselves are minute and inconspicuous cells situated at the tijis of the 

 branches. Cf. Stein, T. iv.

Dujardin, up. cit., p. 294; Senn, p. 149, fig. 103c; Stein, T. iii., Abt. iii., 

 f. 1—14. 



Lismore (344). In llic water of putrid swamps.
