granulated furrows radiating from a small oval avicularium, 

 which is slightly i-aised and nearly in the centre of the zooecium. 

 Thyrostome lofty, oval; a denticle on each side below the middle ; 

 lower lip hollowed. 



Localities. — Orphanage Hill, Geelong (T. S. Hall) ; Mitchell 

 River (J. Dennant). 



This has somewhat the appearance of a Schizoporella, but the 

 denticles at side are of a Lepralian character ; it has not a true 



Lepralia quad rati punctata, n. sp. (PI. XXXV., Fig. 15). 



Zooecia broadly oval, surrounded by one row (in some cases 

 two rows) of subquadrate pores ; middle smooth, convex. Thy- 

 rostome suborbicular, surrounded with 9-10 spines. An avicu- 

 larium with long mandible pointed upwards on each side of the 

 thyrostome. Ooecia globose, sub-immersed, smooth, surrounded 

 by a row of subquadrate pores and two spines on each side of 

 aperture. 



Locality.— CMiton Bank, Muddy Creek (T. S. Hall). 



This is a very distinct and beautiful species, the subquadrate 

 pores are characteristic ; the avicularia show denticles near the 

 base, which are probably the remains of a bar, or, at any rate, the 

 points of attachment of the mandible. 



Lepralia cribrosa, n. sp. (PI. XXXV., Fig. 16). 



Zooecia elongated, convex, with very numerous large pores 

 scattered over the surface. Thyrostome suborbicular, margin 

 slightly thickened, lateral denticles small, no spines and no 

 avicularia. 



Locality. — Jimmy's Pt., Reeves River (J. Dennant). 



This is a very distinct form, the thyrostome is broader than 

 high, and the lateral denticles are very small, too small to show 

 in the figure. 



Lepralia calopora, n. sp. (PI. XXXV., Fig. 17). 



Zooecia irregularly hexagonal ; margins narrow, raised ; 

 surface granulated ; a very regular row of rather large pores all
