Mr. C. O. Waterhouse on new Species of Megalops. 335 
The actinal surface isnot marked out into areole, and is richly 
invested by a number of short, blunt, stout processes, hardly 
to be called spines, amidst which a coarse granular covering 
is to be observed. The poriferous region begins quite sud- 
denly, at about the second fourth of the length of the side of 
the disk (counting from the actinal margin); while this is 
the point at which the pores begin at the middle of each side 
of the disk, the line of demarcation gradually curves upwards, 
so that along the radial axes the pores begin just above the 
apex of the ambulacral groove. ‘The greater part of the sides 
and the whole of the abactinal surface of the disk are covered 
with short sharp spines, which are scattered over them with con- 
siderable profusion, though in no definite order; dotted among 
the spines are pores of moderate size, which are very indis- 
tinctly grouped into pore-areas ; surrounding and separating 
the pores are fine granules, and these are, at apparently irre- 
gularly disposed points, closely aggregated into distinct 
patches; such a patch is found outside the spines which fringe 
the anus. On the abactinal surface the pedicellariz are small 
and scarce; on the actinal they are, though small, much more 
numerous. ‘The madreporic plate is large: and raised above the 
surface. (It has unfortunately been injured in the specimen 
under description.) 
The single dried specimen has the upper surface of a pinkish 
and the lower of a yellowish-white hue. 
Hab. Aneiteum, New Hebrides 
As already stated, the greatest height is 62 millim. ; its 
diameter is 120 millim,
