660 RHIZOPODS OF SYDXEV AND LISMORE, 



Besides those inentioiied above, the only forms of the genus, 

 that I have met with, are j\^. tuhidosa Penard, and N. layeni- 

 forniis Penard (Coogee, 14); also jS'. cariuafa in the .Sydney 

 Water-Supply, and xY. sumosa Cash, from Coogee. 



Genus Quadrula Schultze. 

 QuADRULA SYMMETRICA V. LONGicoLLis Taranek. 



Form with tlie plates in very regular, exactly vertical and 

 transverse, series. 



Length 95-130, breadth -t8-72, orif. 22-30, thick 32/^ 



Coogee (14, 24, 58); Botany (17). 



Cf. Taranek, Monog. d. kebeliden, p.48, T.IO, f.l9. The 

 European type is ovate, with sides arched right down to the 

 orifice, see Cash, I.e. ii., PL 29, f.1-3. Ours are pyrifoi-m, some- 

 times even clavate. (PI. xxxix., f.6, 7). 



Genus C o c h l i o p o d i u m Hertw. k Less. 



COCHLIOPODIUM ASPERUM, n.Sp. (PL XXxix., f.8). 



Test hemispherical, slightly drawn in at the base; dome arched; 

 sides at the base nearly vertical. Substance chitinous, strength- 

 ened with Hint-grains, large and small, scattered. End-view 

 circular. 



Diam. 13-15, dome 10/x high. Lismore. 



There are plenty of these tests in sample 248o, out of a ditch 

 on the ^^^yrallah road. I have not seen the living creature, so 

 cannot be quite certain of the genus. C. f)Uiinbosam is also found 

 here. 



Euglyphina. 

 Genus E u (; l v p ii a Dujardin. 



EUGLYPHA AUSTRALICA, n.sp. (PL xL, f.l).

 sides arching gently down to the orifice, but occasionally slightly 

 fiattened; orifice nai'row, surrounded by two rows of ovate plates 

 (5-7 visible), pointed in front, with serrated edges. Body-plates 

 very characteristic, being recessed both front and back, with a 

 central, projecting spike in each recess. Tests may be found
