A. W. WATERS ON FOSSIL CHILOSIOMATOUS 



scattered over the colony. Aperture 0*12 millim. wide, 0*1 millim. 

 long. 



I cannot attach any importance to the pit round which the zooecia 

 are formed and upon which Mr. Haswell's new genus is founded. 

 The form of the oral aperture is rare in the Celleporidse ; but we see 

 the same thing in C. sardonica, Waters (" Bry. Bay of Naples," Ann. 

 Nat. Hist. 1879, p. 196), also in C. yarraensis, W., in C. intermedia, 

 M'G., and in G. compressa, Busk, with which perhaps the above 

 should be united ; and perhaps these together should form a sub- 

 genus. This may be one of the Gelleporce described by Mr. Tenison 

 Woods in " Tertiary Fossils in S. Australia," p. 5 (Trans. Roy. Soc. 

 of Victoria, vol. vi.) ; but identification with these is impossible, as 

 the zoarial instead of the zocecial characters are described. In de- 

 scribing fossil Bryozoa so little attention has been paid to the most 

 important character, i. e. the form of the oral aperture, that com- 

 parison is often not possible. 



Loc. Living : Holborn Island, Queensland, 20 fathoms. Fossil : 

 Mount Gambier (Loud. Geol. Soc. and Eih., jun., coll.). 



68. Cellepora, sp. 



There are a few cells of a Cellepora which resemble those of 

 C. pumicosa, Busk (non Linn.) ; but the fragment is too small to 

 determine with certainty. 



69. Ltjntjlites gtjineensis, Busk. . 



Cupularia guineensis, Busk, Cat. Mar. Polyz. p. 98, pi. cxiv. 



The specimen in Miss Jelly's collection is very small ; but as the 

 few zooecia correspond in shape with those figured by Mr. Busk, 

 we may safely conclude that the same species is represented. 



Loc. New Guinea (B). 



70. Ltjntjlites cancellata, Busk. 



Limulites cancellata, Busk, Cat. Mar. Pol. p. 101, pi. cxiii. figs. 4-7. 



Loc. Philippine Islands (Busk) ; off Raton, New Guinea, 7 

 fathoms, and from Darnley Islands, Torres Straits, 10-30 fathoms 

 (sent me by Mr. Brazier). 



71. Selenaria marginata, T. Woods. Plate XVII. fig. 71. 



Selenaria marginata, T. Woods, " On some recent and fossil 

 Species of Australian Selenariadae (Polyzoa)," Trans. Phil. Soc. 

 Adelaide, 1880, p. 9, pi. ii. fig. 9, a-d. 



The zocecial cells are very small, and in shape resemble those 

 drawn by Mr. Woods. In some of the zooecia there is a plate, some 

 little distance down the aperture, with a central perforation, so that 

 the zocecium is almost closed. Sometimes the same thing is seen in 

 Cellaria fistulosa both recent and fossil. I hardly understand 

 Mr. Woods's description or plate when he refers to the pore ; but I 

 think this is undoubtedly the species he describes. Aperture 0-06 

 millim. wide. 



Loc. Living : Cape Three Points, 71 fathoms.
