35. Lepralia pertusa, Esjper. fsp.J 



36. Lepralia (ScMzoporella) sp. ? 



Cells sub-ventricose, separated by narrow, raised lines ; mouth, 

 sub -quadrate, surrounded by an inconspicuous rim, a small sinus 

 in the lower lip, and an avicularium on one side above the mouth ; 

 anterior surface covered uniformly with round pores. Colour 

 brown. 



A species so common on the Australian coast that, though I am 

 unable to identify it with any of the described species known to 

 me, I hesitate about giving it a specific name. 



37. Lepralia spinifera, Johnston, var ? 



Cells immersed, slightly ventricose, uniformly ornamented with 

 large j)unctations, a small avicularium on either side of the 

 mouth ; no spines. 



38. Lepralia irregularis, sp. nov., Plate II., fig. 1. 



Cells immersed, not defined; surface ornamented with very 

 irregular, wide fenestrae. Mouth of irregular shape. Colour 

 light purple. 



39. Lepralia (ScMzoporella) Quadlingi, sp. nov., Plate II., fig. 2. 



Cells immersed, not distinctly separated, cell- wall covered with 

 small, somewhat irregular, pentagonal reticulations. Mouth with 

 an open sinus below ; ovicell indistinctly reticulated. 



40. Lepralia (Schizoporella) assimilis, sp. nov. 



Cells ovate, ventricose, surface granular ; a raised avicularium 

 on each side at the top of the cell close to the mouth ; mouth with 

 a narrow sinus in the lower Kp. Ovicells globose, uniformly 

 granular. 



Allied toX. spinifera, Johnston, but distinguisbed by the absence 

 of the characteristic sculpture on the ovicell.
