Diagnosis Test hemispherical, the oral side rather flattened in the adult stage. Primary ambulacral tubercles contiguous throughout the ambulacrum; enlarged secondary tubercles form a vertical series adradial to the primaries, but these tubercles are much smaller than the primaries. Primary interambulacral tubercles not contiguous; enlarged secondary tubercles lie on either side of the primary, on the admedial side about 2 larger ones and 2 or 3 smaller ones, on the adradial side 2–6 usually arranged in horizontal series of 2 or 3, either one series or two such series occurring on alternating plates. The miliary tubercles are scattered thinly on the surface, but around the primary tubercle they form linear series, which are feebly united by sculptured ridges into a radiating pattern of spokes. On immature specimens a similar pattern is seen investing the primary tubercle of each ambulacral plate also, but this later disappears. Oculars all exsert. Primary spines 20 to 30 mm long. [details]
