BKYOZOA FROM S.W. VICTORIA, AUSTRALIA.

Sele7iaria alata, Tenison Woods, " On some recent and fossil 

 Species of Australian Selenariadse (Polvzoa)," Trans. Phil. Soc. 

 Adelaide, 1880, p. 11, pi. ii. fig. 12, a, b, c. 



Loc. Muddy Creek, Miocene Beds near Hamilton, Victoria (W.). 



The specimen is smaller than those described by Mr. Woods, 

 only measuring 2j millim. ■ but otherwise the differences are very 

 small and do not seem sufficient to make it a variety. The specimen 

 may be described as follows : — Zoarium small, orbicular, moderately 

 convex. Zocecia rhomboidal or semicircular, margins distinct ; area 

 depressed, aperture large, narrowed below by triangular alse at each 

 side. Avicularian areas few, not so large as the zocecia. Under 

 surface with radiating grooves. 



All Mr. Woods's figures for the above memoir are drawn upside 

 down, perhaps by an error of the lithographer ; and Mr. Woods 

 seems to have described his species from the figure when he says of 

 the aperture " narrowed above " instead of " below." 



Besides the specimens determined, there are several imperfect 

 fragments of other species, among which there is a badly preserved 

 Lunulites somewhat resembling L. aperta, T. Woods ; and there are 

 a few cells of a species (probably with Lepralia growth) with ven- 

 tricose punctured cells and a long projecting spout below the aper- 

 ture resembling that of L. mamillata (Crag Polyz. pi. vi. fig. 5 c), 

 and a few zocecia of an erect form with elongate subtubular coarsely 

 punctured zocecia with a projecting wide peristome ; each zocecium 

 springs laterally from the one below, in the same manner as in Cri- 

 brillina dentipora, fig. 33.
