Lesquereusia spiculosa, 11. sj). (PL xxxviii., £.4). 



Test broader than long, the tube very straight and distinct, 

 and much to one side, the body with beautifully circular outline. 

 Test smooth, and apparently rather more chitinous than usual, 

 studded with small, straight spicules disposed confusedly, here 

 and there a few coarse Hints, especially towards the centre of 

 the test. The spicules do not appear to be diatoms. 



Length 108, breadth 127, orif. 42/^. Lismore. 



Genus P h r y g a n e l l a Penard. 

 Phryganella acropodia (Hertw. «fc Less.) Hopkinson. 



Diam. 38-54, alt. 21-30; orif. 21-24/x. 



Lismore (278, 321). (PI. xxxviii., f.5).

 I find it difficult to make out the type of this species, and, in the 

 synonymy, have simply followed Hopkinson. Three different 

 forms occur here (PL xxxviii., f.5-7). Cash gives no figure of the 

 side-view, and Penard two different figures. I have adopted the 

 later of these as the type. 



Var. AUSTRALICA, n.var. (PL xxxviii., f.6). 



Test in side-view subtri angular, depressed; basal angles sharper; 

 base almost equal to the diameter of the test; orifice, as in the 

 type, narrower than the base, not visible in side-view\ 



Diam. 42-63, alt. 28-33; orif. 34-36/x. 



Botanic Gardens (3); Lismore (273, 308). 



Var. depressa, n.var. (PL xxxviii., f.7). 



Test in side-view depressed, very little arched above, often 

 nearly Hat, very broadly rounded at the sides, sides running 

 down at an angle to the base, orifice the full breadth of the base, 

 not tucked under the test as in the other two forms, the margin 

 visible in side-view. 



Diam. 40-46, alt. 23-31; orif. 27-34//. 



Auburn (46); Coogee (58); Guildford (23); Lismore (185). 



The type is rarer here than the other two forms.
