Mus. & Geol. Survey Xew Zealand, pt. iv. p. 23) ; but I must con- 

 fess to being unable to understand Mr. Woods's description of the 

 mouth. The specimen from " Yarra-Yarra " is very small and in 

 imperfect preservation. 



61. Schizoporella excttbans, sp. liov. Plate XVI. fig. 56 ; Plate 

 XVIII. fig. 80. 



Zoarium erect, filiform, with a longitudinal row of zocecia on each 

 of the four faces. Zocecia distinct, subhexagonal, upper part much 

 raised, surface granular. Oral aperture depressed, rounded on the 

 distal edge, contracted on each side near the proximal edge, forming 

 a large rounded proximal sinus. Triangular avicularium on raised 

 prominence on a level with the oral aperture, directed downwards. 

 Avicularia sometimes absent, usually on one side only. 



Aperture 0-08 millim. wide, 0*075 millim. long. 



Probably the genus Schizoporella will have to be broken up, and 

 those forms in which the proximal edge of the oral aperture forms a 

 large arc will be separated ; for while the appearance is that of a 

 large sinus, the structure must be different. It is also very diffi- 

 cult to see where the division should be made between Lepralia and 

 Schizoporella ; for the wide rounded aperture of Lepralia with two 

 lateral denticles sometimes approaches very closely in shape that of 

 a Schizoporella with a large and wide sinus. Pig. 56 was drawn 

 from a small fragment in which it was impossible to see the form 

 of the zoarium, and therefore, in this respect, is not quite correct. 

 I have since received specimens showing the erect filiform growth. 



62. Schizoporella amphora, sp. nov. 



Zoarium slender, erect, with a single row of zocecia on each of the 

 four faces, the opposite pairs alternating with the other two. Zocecia 

 irregularly ovate, expanded.and raised in the middle, contracted above 

 and below : distal end of the zoceeium much raised, forming a small 

 peristome which is contracted on both sides near the lower part. 



The specimen is small; and more perfect ones may add many 

 particulars. It may have been sometimes articulated, as seems to 

 have been the case with Cellaria Schreibersi, Ess. 



63. Schizoporella atjstralis, T. Woods. Plate XIV. fig. 15. 



Tetraplaria australis, T. Woods, " On some Austr. Tert. Poss. 

 Corals & Polyzoa," Tr. Hoy. Soc. of Xew S. Wales, 1878, p. 5, fig. 4. 



Zoarium cylindrical, slender. Zocecia facing four ways, the op- 

 posite pairs alternating with the "other two, elongately pyriform ; 

 surface very finely granulated, with extremely fine pores between 

 the granules (but these can only be seen when the preservation is 

 very good) . Oral aperture rounded on the distal edge, slightly curved 

 or straight on the proximal, with a small distinct sinus : aperture 

 0*08 millim. wide, 0-07 millim. long. 



Since I drew the figure I have received a much better specimen, 

 from which I have been able to make out the character of the 

 aperture. The cells are nearly half as long again as in Cellaria
