71. Selenaria concinna^ Woods. (PI. V. fig. 11.) 



Selenaria concinna, Tenison Woods, " Australian Selenariadee," Trans. 

 Phil. Soc. Adelaide, 1880, vol. iii. p. 10, pi. ii. fig. 11. 



The vibracular chamber is elongate, with a row of large 

 pores round the border; above it there is a small tubular 

 projection, and in the zooecium above there is a semicircular 

 hollow. The oral aperture is 0"16 millim. wide. 

 . The central zooecia are partly closed, in a similar way to 

 those of LunuUies petaloides^ d'Orb., as described from Muddy 

 Creek (Q. J. Geol. Soc. vol. xxxix. p. 442, pi. xii. fig. 11). 



This has only been known fossil previously. 



Loc. Fossil: Muddy Creek (Victoria). Living: off Port 

 Stephens, 25 fath. [Brazier). 



72. Selenaria maculata, Busk. 



Selenaria maculata, Busk, Cat. Mar. Pol. p. 101, pi. cxvii, ; Waters, 

 Quart. J. Geol. Soc. vol. xxxix. p. 440, pi. xii. figs. 7, 9, 12 ; id. ib. 

 vol. xii. p. 309 ; Haswell, Polyzoa from the Queensland Coast, p. 42. 



Loc. Living : Holborn Island ; Barnard Island, N.E. 

 Australia, 10 fathoms (dredged by Brazier) . Fossil : Muddy 

 Creek and Bird E-ock (Victoria) ; River-Murray Cliffs (S. 

 Australia). 



73. Selenaria punctata^ T.Woods. 



8ele7iaria purwtata, Tenison Woods, Trans. Phil. Soc. Adelaide, vol. iii. 



1880, p. 9, pi. ii. fig. 8 ; Waters, Q,. J. Geol. Soc. vol. xxxix. p. 440.

Coast," Proc. Linn. Soc. N. S. Wales, vol. v. pt. i. 1880, p. 42. 



This differs from Selenama maculata in the presence of 

 two large pores on the wall of each cell, and the vibracular 

 chamber has a cribriform calcareous cover with much smaller 

 pores than those of 8. maculata. The pores on the front of 

 the zooecium are sometimes denticulated, but this is not so 

 distinct in the recent as in the fossil specimens. 



Oral aperture: Princess-Charlotte Bay, 0"09 millim. wide; 

 Port Stephens, 0*14. The fossil has an aperture nearly double 

 this size. 



Loc. Living: off Cape Three Points, 71 fath. [Woods] • 

 Holborn Island [H.) ; Princess Charlotte Bay, 13 fath. (N.E. 

 Australia, Brazier) ; off Port Stephens, N.S.W., 25 fath., 

 sandy mud bottom [Br.]. Fossil : Muddy Creek.
