3. L. rectUineata, Hincks. PI. X., fig-. 4. 



Lcpralia rcciU\noala. ITincks, A.M.N.H., Oct., 1881; Waters, Q.J.G.S., 1887, 

 p. 60. 



Zoarium encrustiuL;-. Zoa>cia, large, distinct, ovate, convex ; a row of linear 

 pores along the margins, Avitli 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 

 outAvards 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 ujoper edge of the thyrostome. 



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



Lepralid siihimmersa, McG., P.Z.V., 35; llincks, A.M.N.H., Oct., 1884; 

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



Zoarium crustaceous. Zoa-cia large, not much eleA'ated, 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. Ooecia rou.n{lcd, subimmersed.

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



Lepralia pertusa, Busk, B.M.C., XL, p. 80 ; Hincks, B.M.P., 305 ; Escarelta 

 pertusa, Smitt, Ploridan Bryozoa, 11, 55. 



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

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

 pores ; thyrostome widely arched above, contracted toAvards the lower lip, wliich 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.Y. is not the present, but L. pallasiana. 



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