is a series of 8 or 9 long, blunt, compressed or prismatic spines, the 

 innermost largest; on the face of each plate is a single big spine, 

 between which and the tip of the jaw are three or four sharp, 

 angular spinelets; distally a series of 10 or 11 granule-like spines 

 runs along the outer margin, and 5 or 6 much coarser granules lie 

 along the sutural margin. Colour of holotype, in alcohol, yellow- 

 brown; of paratype, dull brownish-red above, more or less irregularly 

 bleached; lower surface, nearly white.

This fine species is quite different from baccatus but is very near 

 corijnetes Fisher and apinosus H. L. C. It is readily distinguished 

 from the former by the spiny upper surface and the pedicellariae 

 on the adambulacral plates, and from spinosus by the bare abactinal 

 plates and the presence of only one large spine on each oral plate. 

 I was at first inclined to consider these specimens as adult baccatus 

 but careful comparison shows that this idea is absurd. The differences 

 in the adambulacral armature are fundamental and cannot possibly 

 be construed as growth stages, and the same must be said of the 

 condition of the marginal plates. One of the specimens from 14232 

 was evidently dried directly from salt water, perhaps with the laud- 

 able purpose of preserving the colour, but unfortunately, with the 

 passage of time, it has disintegrated sadly and is now of little value. 

 It was somewhat larger than the holotype, as r = 30 mm. The 

 present colour is deep red brown, the marginals being darker than 

 the abactinal plates.

Although Bell (1905, Mar. Inv. South Africa, vol. 3, p. 246) recog- 

 nized the fact that this species is very little known, he does not give 

 one word of information about the numerous specimens he had be- 

 fore him, except that the species is now "found to grow to a good 

 size". What "a good size" may be each reader must decide for 

 himself! However, two of Bell's specimens are now in the collection
