TEETIAET CYCLOSTOMATOUS BEYOZOA FEOM NEW ZEALAND. 



0'25 millim. wide, regularly covering the front, while the dorsal 

 surface is sulcate, with elongate pores in the sulci. The front and 

 hack therefore correspond in structure with Hornera. The other 

 specimen has the branches compressed ; but the anterior and dorsal 

 structures are the same. This grows from a small flat base. 



Ceriopora arbusculum. Ess. (Foss. Polyz. AYien. Tert. p. 34, pi. v. 

 figs. 12, 13), has much the same appearance ; but from the meagre 

 description identification is impossible. . 



Should more perfect specimens show that it is advisable to retain 

 the provisional name of CrassoJiornera, the genus must be defined 

 on more satisfactory material. 



There is also a small fragment of a large branching EntalopJiora 

 from "Waipukurau. The zocecia are more or less verticillate, and 

 there are two or more to a row, suggesting a relationship to such a 

 form as Peripora ligeriensis, d'Orb.
