smooth, ef?pecially on the lower lip. Ooecium very smnll, 

 rounded, pitted and tubercular. A transverse aviculariuui, 

 with narrow spatulate mandiLle pointed inwards, about the 

 middle of the zocBcium on one side.

Lepralia Feegkensis, Busk, PI. X, Figs. 1, 3. 



I have two specmiens of" this species sent by Mr. "W'ooster 

 from Nichol Bay, North Western Australia, one on pearl 

 shell, the other on coral. In both, the zooecia are very large, 

 distinct, separated by grooves, slightly convex, and marked 

 with numerous minute granulations and perforations. The 

 mouth is large, coarctate. In the one on shell, there is in most 

 of the zooecia, at each upper angle, a sessile avicularium, with 

 a long pointed triangular mandible directed directly inwards 

 above the mouth. There are several ooecia which are large, 

 rounded, prominent, and marked similarly to the zooecia. 

 In the other specimen, the zooecia are more irregularly 

 disposed, and differ considerably in size. Many have an 

 avicularium on one side of the mouth, close to the angle of 

 zooecium, with the mandible much shorter and broader than 

 in the other specimen, and directed upwards. The projection 

 on each side of the mouth is also rather sharper. 



Busk (Challenger Polyzoa, Pt. I, p. 141, PI. XXII, Fig 9), 

 describes the zooecia as being " completely immersed so as to 

 form an almost level surface, oblong and rectangular, disposed 

 in linear series, surface smooth, and very finely and obscurely 

 punctured." They are figured, however, as separated by 

 well-marked grooves. He also describes the ooecia as 

 inapparent, but does not figure them, and he figures the 

 avicularia as much more slender than in Mr. Wooster's 

 specimens. Busk's specimen was probably younger, and I 

 have no doubt as to the identity of the species. In addition 

 to the Feegee's, it is also recorded from Hong Kong. 



SCHIZOPORELLA PULCHRA, n. Sp., PI. IX, Fig. 7. 



Zoarium encrusting. Zooecia irregularly arranged, ovate 

 or elongated, convex, granular, separated by distinct raised 

 lines ; mouth lofty, a wide deep rounded sinus, separated by 

 a sharp angle on either side ; peristome thickened. Occasion- 

 ally round avicularia, with semicircular mandibles, on 

 sei)arate areas.
