Indian Deep-sea Asteroi'dea. 99 



Actinal interradial areas small, semielliptical iu shape, 

 reaching to the third infero-marginal phite ; about thirty 

 ph\tes in each area, of "wliich those in the row nearest the 

 ambulacrum are much the largest ; all the plates are closely 

 covered with prismatic granules, grouped, except in the 

 particularly large adoral ])air of plates, in paxilla-form. 



Anus central but indistinct. Madreporiforra plate almost 

 completely hidden, rather nearer to the marginal plates than 

 to the centre. 



Ambulacral furrow narrow. 



Colour in tlie fresh state light pink. 



Laccadive {Sea, 740 fathoms, coral-mud. 



This species appears to be closely related to Astrogoniuin 

 fallax, Perrier (Ann. Sci. Nat. tom. xix., 1885). Guided' by 

 the work of Mr. Sladen and by the description and tigures in 

 the ' Boston Journal of Natural History,' vol. vi., 1857, 

 p. 530, pi. xxiii., I have placed it, though not without 

 misgiving, in Stimpson's Pacific genus. 



Antiienoides, Perrier. 



34. Anthenoides sarissa, sp. ii. 



Pays 5. P = 2-5 r. R=:46 millim. in the 

 type specimen. 



Disk large, flexible, inflatable, especially in the interradial 

 areas ; rays moderately long, rigid, broad at base, but quickly 

 becoming narrow and then tapering. 



The abactinal surface of the disk and of the rays, except 

 at the extreme tip, where the supero-marginal plates meet 

 across, is cased by flat plates which are covered with a finely 

 and distantly granulose membrane ; these plates are of two 

 kinds and of two modes of disposition : — (i.) large stellate or 

 somewhat polygonal plates arranged in series radiating from 

 the centre of the disk, and (ii.) small or minute platelets inlaid 

 everywhere between the large plates. Papula emerge in the 

 scams between tlie plates everywhere except in a narrow band 

 in each interradius. 



The marginal plates, which number about 20 in each 

 series, are large and finely and distantly granular. The 

 supero-marginals form a very broad bevelled margin to the 

 disk in the interradii and a narrower margin to the rays, 

 except in the distal third of the latter, where they nearly meet 

 across the ray ; except for one, two, or three snuill inconstant 

 papilliform pedicellariai occurring on the extreme distal edge
