Japan under the name of Tubulipora continua ; but, judging from the brief 

 description and the figure given of it by him, I should think that form can 

 scarcely be separable from the present species.

There exist in the collection numerous large colonies which are re- 

 ferable to this species. The localities are : Yodomi (62-78 fms.) ; off to 

 west of Niijima ; off Kôzushima (depths unknown) ; shallow water near 

 Misaki. The specimens vary considerably in zoarial shape. While some 

 are without the cross-connections between branches as was noted by 

 Harmer on Japanese specimen of the species preserved in the Cambridge 

 Museum, the majority show the said connections. In all cases the ovicells 

 agree well in their character with the same in the ' Sieboga ' specimens, 

 described by the above author under the same species. 



17. Tubulipora radiata n. sp. 



Zoarium shaped like an outflaring funnel about 25 mm. or less in 

 diameter, consisting of short dichotomous branches, pointed at end and all 

 arising from the upper end of a short stem. Zooecia arranged in alternating 

 lateral series ; each series consisting usually of three, sometimes of two or 

 four zooecia. The first or the innermost zooecium in a series prominently 

 projecting, distinctly laterally bent, and nearly concealing all other zooecia 

 of the same scries ; with orifice mostly provided on the inner side with a 

 lip-like process broad at base and narrowed towards apex. All other 

 zooecia in the same series without the lip-like process at orifice, growing 

 shorter by degrees towards the outer end of series. Ovicell occurs either 

 near free end of branches or at their bifurcation point ; it is a weak inflation
