634 RHIZOPODS OF SYDNEY AND LISMORE, 



Results. — Altogether 174 forms have been listed (including a 

 few Heliozoa), representing 118 species belonging to 40 genera, 

 a very fair result considering the character of the habitats, and 

 that, with the exception of Lismore, the gatherings in each 

 locality are mostly from one and the same spot. Of these, 80 

 are here described as new, 30 being accorded specific, and 50 

 varietal rank. Three new genera are proposed. 



Amoebina. 



Genus A m ce b a Ehr. 

 Amceba PROTEUS V. NOBiLis (Penard) mihi. 



Syn., Amoeba nobilis Penard, Faune Rhiz., p. 65. In a gather- 

 ing out of a mere on grass-land, I came across this immense 

 form, equal in size to ten ordinary specimens, which, though in 

 motion and spread out in front in a palmate-digitate shape, 

 measured no less than 950/x long and 350/x broad, more than 

 twice as large as Cash's var. granulosa. Nor was it a solitary 

 example; with a Coddington lens, I noted many others on the 

 sides of the glass phial. Passing under a filament of Spirogyra, 

 the tail-end, the size of an ordinary specimen and containing 

 three empty tests of Lesquereusia, got caught, and the main body 

 broke away from it. The deserted portion exhibited slight 

 amoeboid movements for a time, but did not move from its place 

 or throw out any pseudopodia. 



Lismore (254). 



Amceba verrucosa v. quadrilineata (Carter) Playf. 

 Biol. Richm. R., p.l44, PI. viii., f.l7, 19. Syn., A. quadri- 

 lineata Carter, in Ann. Nat. Hist., 1856, p.243, T. v., f.3; A. 

 striata Penard, Mem. Soc. Phys. Geneve, 1890, p. 127, T. ii., ff.31- 

 34. Var. maxima Playf., I.e., must be included here, as the type 

 appears to run to vastly greater dimensions in Europe. The 

 usual size here is about 50-60/x long; the largest, I have seen, 

 reached only double that amount. If this form is to be raised 

 to specific rank. Carter's name has priority, unless it can be 

 proved identical with A.striolata Perty; Kleinst. Lebensf., 1852, 

 p. 188, T. viii., f.l5. A Umax Duj., which seems to we a form 

 of A. verrucosa, I have also noted here.
