REPORT ON THE ASTEROIDEA. 205 
the outer spinelets of the adambulacral armature, which are usually grouped together into 
an incipient pedicellaria (?). 
The mouth-plates are elongate, and covered with comparatively long, closely placed 
spines, which are flattened and more or less subspatulate. The two inner spinelets, placed 
side by side on each plate, are longer and larger than the rest ; and these, together with 
their smaller lateral companions, form a horizontal comb of six to eight spinelets directed 
towards the centre of the mouth. Behind these inner spinelets follow two or three shorter 
spines in lineal series on the surface of the plate; these are succeeded by eight or nine 
pairs of short, flat spines, closely placed and occupying the middle portion of the surface, 
on which they stand perpendicularly ; and the outer part of the plate carries three or four 
spines in single line directed outward, their length and robustness increasing as they 
recede from the mouth. The next adambulacral plate to the mouth-plates is narrow, 
and the spines thereon are small, uniform, and arranged in two lineal series apposed to 
one another. 
The madreporiform body is obscured by paxille. 
The ambulacral tube-feet are small and terminate in a point, which is tipped with 
black, and gives a very singular appearance to the species. 
The terminal plate has a slight furrow abactinally, suggesting the line of union of two 
primitive plates. 
Colour in alcohol, yellowish grey. 
Locality—Station 192. In the Banda Sea, between the Ki Islands and Banda Islands. 
September 26, 1874. Lat. 5° 49’15”S., long. 182° 14’15” E. Depth 140 fathoms. Blue 
mud. Surface temperature 82°°0 Fahr. 
Remarks.—Vhis species has some alliances with Astropecten scoparius and Astro- 
pecten mauritianus, but is distinguished by the spinulation of the infero-marginal plates, 
and by the character of the armature of the adambulacral plates.

Remarks.—A large series of this species was obtained. I have compared them with 
the original type-specimens of Miiller and Troschel belonging to the Leyden Museum.
