Zoarium unilaminate. Zooecia indistinct, but witli a dejiression between them ; 

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

Zoarium unilaminate. Zocecia distinct, ovate, A\ithout raised margins, convex, 

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

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

SchizoporeUci JUiformis, Waters, Q.J.G.S., 1882, ]). 274. 



Zoarium cylindrical, with about six rows of zoa^cia. Zooecia alternate in 

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

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

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

 denticle on each side, peristome raised. 



S.P. 



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

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



16. -L. duplex, n.sp. PI. X., fig. 16. 



Zoarium probably bilaminate. Zocecia much elongated, narro"w, separated by 

 raised margins, nearly fiat, obscurely divided by the markings into U\o portions, the 

 upj)er with a row of deej) areoke round the margins and a second row of similar but 

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

 pores or areolae occupying th(! whole width of the zoa'cium ; thyrostome wide, nearly 

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