A MONOGRAPH OP THE TERTIARY POLYZOA OP VICTORIA. 75 



small round pores ; thyrostome contracted below, lower lip straight or slightly 

 hollowed. Dorsal surface with the zooecia distinctly shown separated by flat 

 thickened margins immediately within which is a row of large pores ; other smaller 

 pores or pits scattered over the surface.

13. L. vermicularis, n.sp. PI. X., fig. 20. 



Zoarium unilaminate. Zooecia indistinct, hut with a depression between them ; 

 upper part slightly raised forwards ; surface with irregularly shaped pores and 

 areolations separated by sinuous convex ridges ; thyrostome arched above, the lower 

 lip nearly straight ; peristome thickened.

14 L. hamiltoniensis, n.sp. PL X., fig. 24. 



Zoarium unilaminate. Zocecia distinct, ovate, without raised margins, convex, 

 obscurely granular, an irregular row of pores or deep round areolae along the 

 margins and occasionally a few others on the surface ; thyrostome semicircular, the 

 lower lip slightly hollowed, a denticle on each side ; an avicularium to one side of 

 the thyrostome.

15. L. Jiliformis, Waters, sp. PI. X., fig 28.. 



Schizoporella Jiliformis, Waters, Q.J.G.S., 1882, p. 274. 



Zoarium cylindrical, with about six rows of zocecia. Zocecia alternate in 

 longitudinal series, elongated, somewhat quadrate at the extremities, separated by 

 prominent smooth straight margins ; surface punctate and granular, very slightly 

 convex ; thyrostome higher than wide, arched above, hollowed below, with a sharp 

 denticle on each side, peristome raised. 



S.P. 



Waters refers this species to Schizoporella, but the hollow in the lower lip is 

 not a true sinus, and the oral denticles shew that it ought to be placed in Lepralia. 



16. L. duplex, n.sp. PL X., fig. 16. 



Zoarium probably bilaminate. Zocecia much elongated, narrow, separated by 

 raised margins, nearly flat, obscurely divided by the markings into two portions, the 

 upper with a row of deep areolae round the margins and a second row of similar but 

 smaller pores within these, leaving a clear central space, the lower portion with large 

 pores or areolae occupying the whole width of the zocecium ; thyrostome wide, nearly 

 semicircular, but with the upper margin slightly flattened, the lower lip slightly
