 p. 82, pi. x. figs. 9-13 ; pi. xii. fig. 14 ; pi. xiv. fig. 7. 



Of the several broken specimens one is 32 ■ 5 cm. in length, and 

 is very stout and straight, difficult to bend or break. It is thickly 

 covered with ccenenchyma, and the polyps are arranged all round 

 the axis. They are not all of the same size, the largest being 

 about 2 mm. in diameter. They stand out prominently, about 2 mm. 

 high. The tentacles are long and tapering, and the mouth is pro- 

 minent. The axis is thicklycovered with spines and is 5 mm. in 

 diameter ; the central canal is only 1 mm. in diameter. The spines 

 are short and thick, and are longer on one side of the stem than 

 on the other. They stand out at right angles to the axis, but are 

 not arranged in any definite order. 



Locality. — Portuguese East Africa. Previously recorded from 

 New Guinea. 



Cirripathes spiralis Linn. 



See Brook, Report on the Antipatharia of the ' Challenger ' Expedition, 



p. 85, pi. xii. fig. 10. 



Of the two specimens, one is spirally coiled, 33 ■ 3 cm. round 

 the spiral, and 8*5 cm. high; the other is twisted irregularly, 

 33 • 4 cm. in length. On the spiral specimen there are only a few 

 polyps left ; the other has numerous polyps, but badly preserved. 

 They are crowded together and are arranged all round the axis. 

 They are circular, 2 mm. in diameter ; the tentacles are long. The 

 ccenenchyma is very thin. The axis, which is not very stout, is 

 black in colour. Its diameter is 1 mm., while that of the central 

 canal is • 5 mm. The spines are short and conical, and are longer 

 on the outer side of the spiral than on the inner. They are arranged 

 in spirals and longitudinal rows, eleven of which can be seen from 

 one aspect. The members of a row are about one length apart. 



Locality. — Portuguese East Africa. Previously recorded from 

 the Indian Ocean, Molucca, Norway, Mediterranean, Ceylon, 

 Kurrachee, and the East Indies. 



Stichopathes diversa (Brook). 



See Cirripathes (?) diversa Brook, Report on the Antipatharia of the 

 'Challenger' Expedition, p. 87, pi. 12, fig. 12. 



A stout spiral, 15 cm. high. The polyps are arranged on the 

 outer side, while the inner is left bare. They are straw-coloured in 

 spirit, and are very flat, with long tentacles and prominent mouth. 

 There are two types of spines, large ones with small ones between
