72 A MONOGRAPH OF THE TERTIARY POLYZOA OF VICTORIA. 



3. L. rectilineata, Hincks. PI. X., fig. 4. 



Lepralia rectilineata, Hincks, A.M.N.H., Oct., 1884 ; Waters, Q.J.G.S., 1887, 

 p. 60. 



Zoarium encrusting. Zooecia, large, distinct, ovate, convex ; a row of linear 

 pores along the margins, with occasionally others internally, numerous shorter pores 

 at the sides of and above the thyrostome ; thyrostome large, rounded above, 

 contracted below, the lower lip arched upwards, a sharp denticle on each side above 

 the angle ; an elliptical avicularium, with the mandible directed downwards and 

 outwards on each side below the thyrostome. 



M. Living. New Zealand. 



This seems to be identical with Hincks' species, although the thyrostome 

 differs slightly and the pores are somewhat differently arranged. There seems to 

 have been a row of pores along the upper edge of the thyrostome. 



4. L. subimmersa, McG. PI. X., figs. 5, 6. 



Lepralia subimmersa, McG., P.Z.V., 35 ; Hincks, A.M.N. H., Oct., 1884 ; 

 Waters, Q.J.G.S., 1885, p. 299. 



Zoarium crustaceous. Zooecia large, not much elevated, with narrow raised 

 margins ; surface with numerous small round pores ; thyrostome large, the lower 

 lip slightly hollowed and an internal denticle at each angle ; an elliptical transverse 

 avicularium on the middle of the lower lip. Ocecia rounded, subimmersed. 



B. ; M. Living. Australia. 



5. L. pertusa, Esper, sp. PL X., fig. 8. 



Lepralia perhisa, Busk, B.M.C., II., p. 80 ; Hincks, B.M.P., 305 ; Escarelia 

 pertusa, Smitt, Eloridan Bryozoa, 11, 55. 



Zoarium crustaceous. Zooecia ovate, very convex, arranged in linear series 

 separated by very narrow raised margins ; surface with numerous small round 

 pores ; thyrostome widely arched above, contracted towards the lower lip, which is 

 straight or slightly hollowed, a small denticle at each angle ; peristome slightly 

 raised above, thin. 



M.C. Living. Europe, North America, Australia. 



The species described and figured in P.Z.V. is not the present, but L. pallasiana. 



6. L. nodidosa, n.sp. PI. X., fig. 9. 

 Lepralia cleidostoma, var. rotunda, Waters, Q.J.G.S., 1881, p. 336.
