One of the specimens from St. 156 was photographed before preservation (Plate 

 VIII, fig. 3). The colour in life is stated to be "disk bright red above with all the 

 plates white". A specimen preserved in formalin (St. WS 806) still shows very faint 

 traces of the red colour ; the specimens preserved in alcohol have lost all colour, except 

 one from St. WS 816, which shows the red colour better than does the specimen in 

 formalin. 



Some of the specimens (St. WS 815) might equally well be identified as Ophiosteira 

 Senouqui, there being in reality no sharp limit between these two forms, in spite of 

 their being designated by two different generic names (cf. above, p. 315). 



The character of the gonads, as was to be expected, is exactly as in O. Senouqui. Also 

 the colour of the live specimens is the same in the two species, there being a note about one 

 of the specimens from St. 152 stating: " disc bright red above, with all the plates white". 



Ophiuroglypha tumida, Mortensen 



Ophiitra {Ophiiiroglypho) tumida, Mortensen, 1933. Echinoderms of South Africa. Papers from 

 Dr Th. Mortensen 's Pacific Exped., lxv (Vid. Medd. Dansk Naturh. Foren., 93), p. 387, 

 pi. xix, figs. 22-23. 



St. 436. 20. ix. 30. Off Durban, 416 m. 4 specimens. 



Although the plates of the dorsal side of the disk of these specimens are somewhat less 

 tumid than in the typical form there can be no doubt that they belong to this species, 

 the more so as they are from the type locality.

St. 363. 2-5 miles S 80° E of SE point of Zavodovski Island, South Sandwich Islands, 329-278 m. 

 I specimen. 



This is a large specimen, 21 mm. in diameter of disk; all arms broken off close to the 

 disk. One of the interradii is partly lacking, apparently on account of a wound, which 

 has, however, healed up again. Some Foraminifera are found attached to the disk plates.
