Mr. A. W. Waters on Australian Bryozoa. 199 



Loc. Fossil : Victoria. Living : Curtis Island {H.)] Naples; 

 Port Phillip Heads {MacGf.) ; New Zealand; and Green Point, 

 Port Jackson, 8 fath. (sent by Brazier). 



67. Cellepora ovoidea (And.). (PI. VI. figs. 14, 19.) 

 Cellepora ovoidea, Aud. Descr. de I'Egypte, pi. viii. fig. 7. 



Zoarium irregularly lobed, forming a mass about 2 centim. 

 across ; has started on a small stalk of seaweed. Zooecia with 

 a few pores, a prominent rosti'um without avicularia below 

 the mouth. Operculum slightly convex on the lower edge^ 

 and somewhat broader below, but not usually so much as in 

 the figure. Between the zooecia there are large, spatulate, 

 vicarious avicularia, and there is a moderate-sized lucida 

 about the middle of the mandible ; there is no columella, and 

 the lower edge is straight. 



The ovicell is globular and smooth, usually surmounted by 

 a mucro which sometimes is considerably raised. The ovicell 

 is widely open in front, and projects over the aperture of the 

 raised zooecia. 



There is also C ovoidea^ Lamx., but the figure and descrip- 

 tion are not sufficient to enable it to be recognized. 



Loc. Vaucluse Point, Port Jackson, 5 fath. 



68. Conescharellina incisa (Hincks). (PI. VI. fig. 26.) 



Lunulites incisa, Hincks, Ann. & Mag. Nat. Hist. ser. 5, vol. viii. p. 68, 



pi. iv. figs. 1-3. 

 Conescharellina conica, Haswell, Proc. Linn. Soc. N. S. Wales, vol. v. 



pt. i., 1880, p. 42, pi. iii. figs. 7, 8. 



Hincks and Haswell both described this about the same 

 time, and it is not clear which had priority ; but as there is 

 Batopora conica^ Seguenza, and Lunulites conica, Defr., it 

 would seem necessary to drop that name. 



An important avicularian character has been overlooked by 

 both Haswell and Hincks, namely, that on the cross bar, 

 besides the central ligula, there is a smaller one on each side. 

 The zooecial chamber is long, and there is a straight row of 

 about eight rosette-plates along the edge of the wall. 



This may be Lunulites angulopora, T. Woods, but appa- 

 rently the avicularia were mistaken for the zooecial cells, and 

 the zooecia for vibracula. 



Loc. Holborn Island ; Bass's Straits ; Port Stephens, 25 

 fathoms, '^ sandy mud bottom " ; N.E. coast of Australia, 

 23 fathoms (these latter sent by Mr. Brazier are smaller than 

 the others).
