THOMSON AND RUSSELL— AXIFERA. 1 IS 



10 cm. in height and is feebly branched. There are usually three or four polyps in a 

 whorl, but some branches show five polyps in a whorl. These branches also show the 

 '• covered way " so well seen in S. allmani, formed by the enlarged basal sclerites of two 

 adjacent rows of polyps. While the elongated ccenenchyma spicules typical of *S'. parca 

 were found in some cases, many were considerably broader than the one figured by 

 Versluys. Large reproductive bodies wei'c found in some of the polyps ; tlieir nature 

 will be discussed in a subsequent communication. 



Localitxj. Saya de Malha (C 20), 300-500 fms. 



Previously i-ccorded from Ceram Sea, 1.300-1033 metres, and Banda Sea, 1595 metres 

 [Yersluys, 1900). 



6. Stachyodes clavatu, Versluys. 



For description see: — 

 Versluys, J. : Gorgon. Siboga-Exp., Monog. xiii.* 1906, pp. 98-101, 6 figs. 



The collection includes three fine specimens of this species. One is almost 

 complete, and shows the base, which is 4 mm. broad and somewhat calcified. The main 

 stem is 3 mm. thick. The largest colony reaches a height of 13 cm. and a breadth of 

 6 cm. All the polyps look downward. The colour when living was light pink, in spirit 

 pure white. 



Locality. Providence (D 8), 125 fms. 



Previously recorded from Kei Islands, 20i metres {Versluys, 1906). 



Genus PLUMARELLA. 



7. Flumarella delicatissima, Wright and Studer, var. n. dentata. (Plate 9. 

 fig. 3; Plate 13. tig. 10.)

 Versluys : op. cit. 1906, pp. 14-15, 1 fig. 



Several specimens, about 12 cm. by 9 cm., resemble very closely this species of 

 Flmnarella, which occupies a somewhat isolated position in the genus. Dr. Versluys, 

 who was kind enough to look at a specimen, expressed his opinion that it should be 

 referred to P. delicaiissima, but a study of the scales (see PI. 13. fig. 10) leads us to 

 suggest a new variety. The distribution is remarkable. 



Locality. Providence (D 8), 125 fms. 



Previously recorded from West Coast of Patagonia, 1-10 fms. ( Wright and Studer, 

 1889).
