which is not mentioned by Sladen. Bell (1905, Mar. Inv. South Africa, 

 vol. 3, p. 242) lists the species from five stations but gives no data 

 about the specimens. It way be mentioned here that he, consistently 

 and erroneously, throughout his report gives the date of Sladen's 

 CHALLENGER report as 1887.

PSEUDARCH ASTER BRACHYACTIS *, sp. nov. 

 Plate XII. Figs. 1, 2. 



R = 33mm.; r = 15mm.; R = 2-2r. Br = 18mm., with paxillar 

 area 6 mm. wide at same point. Disk large, flat, about 6 mm. thick. 

 Arms also flat and nearly as thick as disk, except distally ; they 

 taper rapidly from the wide base to the bluntly pointed tips. Inter- 

 brachial arcs broadly curved. Abactinal area of disk and rays, 

 within the boundary of superomarginals, covered by low pseudo- 

 paxillae which typically bear one central granule and a marginal 

 series of 6-8 ; the granules are large, somewhat angular, rather close- 

 set and more or less nearly subequal; near the superomarginals the 

 granule-bearing plates lose their tabulate form and the granules are 

 arranged more or less evidently in rows parallel to the margin. 

 Madreporite small but distinct, about half way between the inner 

 end of the superomarginals and the center of the disk. Supero- 

 niarginal plates very oblique, approaching the horizontal, in position, 

 about 22 on each side of each ray but the distalmost three are very 

 small, with their inner ends abutting on the somewhat swollen but 

 not large terminal plate; the two plates on either side of the inter- 

 radial line are about 5 mm. wide, but only 1 mm. long at the outer 

 end and less than 1-5 mm. at the inner; the succeeding plates gra- 

 dually become longer and narrower but even near the tip of the ray 

 they are twice as wide as long; each plate is closely covered by 

 granules like those on the pseudopaxillae but more rounded; the 

 largest granules (-25-* 30 mm. across) are at the outer (lower) end of 

 the plate while the smallest are along the inner margin ; there are 

 no spinelets or tubercles on any of the plates. Inferomarginals 

 exactly like those of upper series, with granulation and end-width 

 reversed ; on all however, one or more (sometimes as many as four) 

 of the median granules is, or are, enlarged, lengthened and flattened 

 to form a small and appressed but distinct spinelet; the largest of 

 these however rarely exceeds half a millimeter in length and they
