pairs, forming a cordate joint fringed on the side, and separated 

 from each other by a very narrow cylindrical articulation ; the 

 coral is glassy, and nearly transparent. 



Fam. SERTULARIAD.E. 



147. Dynamene bispinosa. Gray. 

 Inhabits New Zealand. Dr. Sinclair. 



Coral slender, branched ; the cells rather distant, small, in 

 pairs ; the tubular mouth, obliquely truncated, ending in two 

 minute spines : vesicule large, ovate, oblong, with a small tooth 

 on each side near the top, near D. operculata. 



148. Dynamene abietinoides. Gray. 

 Inhabits New Zealand. Dr. Sinclair. 



Coral slender, branched, branches pinnate, compressed, simple ; 

 cells rather close, subopposite, ovate, tubular, mouth denticulated ; 

 vesicules large, oblong ovate, with a long process on each side 

 near the mouth. 



Like D. abietina, but the vesicule with two long horn-like 

 processes, and the mouth of the cells toothed. 



149. Sertularia Johnstoni. 



Inhabits New Zealand Dr. Sinclair. 



Coral slender, branched; cells small, distant, alternate, tubular 

 short, oblique, with three or four short teeth round the mouth ; 

 vesicules rather large, oblong, swollen transversely, wrinkled. 



Like Sertularia rugosa, the vesicles resemble the figures 

 (Johnst., Brit. Zooph., t. 8, f. 4, 6) of the cells of that species. 

 May not the true cells have been overlooked ? 



150. Plumularia Banksii. Gray. 



Inhabits Dusky Bay, New Zealand. Sir Joseph Banks. 



Stem compound, branched ; branchelets simple, opposite, pin- 

 nate, unilateral, incurved ; cells close, rather crowded, bell- 

 shaped, toothed at the mouth ; vesicles ? 



Allied to P. myriophyllum (Johnst., Brit. Zooph., 145, t. 29, 

 f. 4 and 8), but more branched. 



151. Thuiarii Zelandica. 



Inhabits New Zealand. Dr. Sinclair. 

 Pale brown, erect, branches oppositely pinnate; cells small,
