BRY0Z0A FROM S.W. VICTORIA, AUSTRALIA.

and which seems to branch without joints. It seems to correspond 

 with the above ; but there is reason for doubting whether too many 

 species have not been made, as Onchopora ventricosa, Hasw., and 0. 

 granulosa, H., are very closely allied. 



Log. Holborn Island, Queensland, 20 fathoms. 



55. SCHIZOPORELLA EENESTRATA, Sp. UOV. 



Zoarium in Eschar a-ioim. Zocecia indistinct, surface smooth. 

 Oral aperture very large, in a very deep depression, rounded on the 

 distal edge, with a sinus on' the proximal; a small rounded avicularium 

 within the oral depression, and a small rounded one below the aper- 

 ture with avicularium opening with numerous denticles. Very large, 

 erect, angular avicularium between the zocecia. Oral aperture 0*17 

 millim. wide. 



The large deep depressions round the large aperture, together with 

 the smooth surface and small avicularia, gives the zoarium the ap- 

 pearance of the network of Metepora ; and the specimen was sent to 

 me marked Betepora. I therefore call it fenestrata, although, of 

 course, it is clear that it is here the magnified aperture which repre- 

 sents in appearance the unmagnified fenestrse of Betepora. 



56. SCHIZOPORELLA, Sp. 



Zocecia perfectly parallel, oblong, distinctly divided laterally, ter- 

 minal divisions scarcely distinguishable. Surface smooth. Oral 

 aperture large, 0*3 millim. long, 0-22 millim. wide, rounded above, 

 apparently triangular below ; frequently a notch on one side, as 

 if regularly broken down ; perhaps there is an avicularium inside 

 the aperture below the notch. The back of the cells is also smooth, 

 showing the lateral parallel divisions distinctly, with an oval open- 

 ing 0-4 millim. long, i. e. about half the length of each zocecium. 



There are one or two species in which there is a similar oval 

 opening on the dorsal surface ; but at the*present moment I do not 

 find any note or reference to such, except in Hemeschara gemi- 

 nipora, Ess.

This somewhat resembles 8. biaperta ; but the state of preserva- 

 tion is not sufficiently satisfactory for definite determination. The 

 aperture is much smaller than in the last species ; and there are 

 numerous round avicularia scattered over the cell. The walls of 

 the ovicells, which have been considerably raised, are broken down. 

 This may be Escharipora Lawderiana, Stol. (Bry. Orak. Bay, p. 136, 

 pi. xx. fig. 1); but the figure and description are so unsatisfac- 

 tory that it is impossible to know where Stoliczka's specimen 

 should be placed. The fossil specimen is in the Eschar a-form. 



A specimen in the British Museum, sent by Mr. Hutton, marked 

 Lepralia reticulata, seems to be this species. The oral aperture of 

 the recent specimen is rounded on the distal end, with a smaller arc 

 forming a sinus on the proximal.
