P.F. 19054. Nanquas Peak, Algoa Bay, N. by E., 11 miles. 57 fms. 

 M. 2 specimens; adult. 



False Bay, Cape Colony, 20-30 fms. 2 specimens; adult. 



Mossel Bay, Cape Colony. 1 specimen; adult. 



Bathymetrical range, 20-204 fms. 



Colour in life: dark or pale violet, either uniform or with a dark 

 angular ring on the upper surface on a paler ground colour. 



PTERASTER AFFINIS. 



E. A. Smith, 1876. Ann. Mag. N. H. (4), vol. 17, p. 108. 

 1879, Phil. Trans., vol. 168, pi. 16, fig. 5. 



The specimen before me has R = 28-30 mm., r = 15 mm., so 

 that R = l'8-2r. It is thus considerably larger than Smith's type 

 but it agrees with his description so well that I have no doubt it is 

 the same species. The colour in alcohol is light dingy yellow. 



P.F. 2798. Vasco de Gama Peak, Cape Peninsula, N. 71 E., 

 18 miles. 230 fms. St. 1 specimen; adult, probably. 



DlPLOPTERASTER MULTIPES.

The occurrence of this northern species off the Cape of Good Hope 

 is indeed remarkable. One of the specimens has R = 25 mm. and 

 the other has R = 55 mm. I have compared them with a specimen, 

 taken in 207 fms. off the northeastern coast of the United States, 

 and there is no doubt, in my mind, of their identity. Fisher (op. 

 cit. p. 371) has given a key to the three known species of Diplopter- 

 aster and these specimens run down at once to multipes. One would 

 naturally expect one of the two southern species to be the South 

 African form. Sladen can hardly have compared this species with 

 Retaster cribrosus when he placed Diplopteraster in the synonymy of 

 Retaster. 



P.F. 14532. Cape Point N. 50 E., 18 miles. 180 fms. Gn. s., 

 blk. spks. 2 specimens; 1 adult and 1 young. 



HYMENASTER LATEBROSUS.

The single specimen, which I refer to this species, has R = 27 mm. 

 and r = 15 mm., but two of the arms seem to have been bitten or
