specimen I was in doubt as to whether Tennysonia might be I. contorta 

 or Qrisina cancellata. 



Loc. Living : Algoa Bay. Fossil : near Napier.

A small fragment from Shakespeare Cliff, Wanganui, is without 

 any doubt the same as a recent Entalopliora, which is apparently not 

 uncommon in New-Zealand and Australian seas. It frequently 

 anastomoses and forms dense intricate masses ; the zoaria are 

 about 1*5 millim. in diameter, and the zooecia are irregularly placed, 

 often bulging out towards the end, but become narrower again at 

 the aperture, which is about 0*13 millim. wide. 



In the zooecial tubes there are always a large number of minute 

 rays with club-shaped heads, on which there are numerous tubercles. 

 I have called attention (Ann. Mag. Nat. Hist. ser. 5, vol. iii. p. 27 G) 

 to similar rays in Lichenopora radiata, and pointed out that these 

 rays, or " hair-like teeth," had globular terminations ; and in that 

 species there are fewer tubercles on these heads, in fact they are 

 usually cruciform. Professor Nicholson has figured and described 

 similar rays in Heteropora pelliculata, Waters ; and these I have also 

 figured in this Journal, vol. xl. pi. xxxi. fig. 28, but have not yet 

 been able to see that the heads are tuberculated. They also occur in 

 a species of Tuhulipora, besides Lichenopora pristis, MaeG., L. can- 

 cellata, L. radiata, and L. Houldsworthii, B. 



The size and arrangement of the zooecia are similar in the recent 

 and fossil examples ; and, after having made the determination by 

 these characters, it was no small satisfaction to find that in the zooecial 

 tubes these minute rays were preserved, thus confirming the absolute 

 identity of the two. 



Loc. Living : New Zealand ; Port Phillip and Port Phillip Heads 

 (W.) ; New South "Wales {H.). Fossil : Wanganui (base of Shake- 

 speare Cliff). 



5. Entalophoea wangantjiensis, sp. nov. (PL XVIII. fig. 1.) 



Zoarium 2*5 millim. in diameter ; about ten zooecia in a complete 

 series. Distance of series about 1-2 millim. apart. The ends of the 

 zooecia but slightly projecting ; surface pitted, with small pores in the 

 centre of the pits. The zooecia are very distinct and rounded, giving 

 the whole a columnar appearance, and are usually arranged round 

 the zoarium in a verticillate manner ; but sometimes the arrangement 

 becomes irregular. The closure, which occurs at about the level of 

 the border of the zoarium, is present in many of the zooecia, and 

 has numerous large perforations. This has as large zooecia (aperture 

 0-4 millim.) as any Cyclostomata with which I am acquainted, being 

 about the same size as those of Cinctipora elegans of Hutton ; but 

 in that species the zooecia do not project at all, nor are the ends
