I cannot agree with Mr. Busk in uniting this with Chorizopora, 

 which has the proximal edge of the operculum straight, whereas in 

 the ordinary zooecia of S. hyalina there is a wide sinus, and it is 

 only in the fertile cells that the proximal edge is nearly straight 

 (see figs. 42, 43). Mr. Busk identified what we now know as 

 Cliorizopora Brongniartii, Aud., with Savigny's figure of Flustra 

 Brongniartii ; and as this has been generally accepted it would not 

 be advisable now to change the name, though I quite agree with 

 Mr. Busk in doubting whether Savigny's figure was meant to 

 represent the species.

A specimen from Shakespeare Cliff has a free globular form, 

 about 6 millim. in diameter ; two specimens from Napier are adnate 

 on shell, while another is a large solid branching form. In none is 

 the preservation very satisfactory, and no spines are seen, so that 

 perhaps they should be called var. hastigera, B. The proximal edge 

 of the oral aperture is more curved than in my recent specimens, 

 and in this respect more resembles var. hastigera.

The fossil from Waipukurau is adnate, aud shows the attachment 

 of the two spines very clearly.

 A specimen from Napier occurs in a thick solid branching form. 

 The minute characters are made out with difficulty.
