37, 
SPOLIA ZEYLANICA. 
Ophiactis savignyi, M. & T.—Seventy-eight specimens, 
mostly very young. 
Ophiothrix longipeda (Lam’k.).—One small specimen. 
Ophiothria exigua, Lyman.—One small specimen. 
Ophiothrix nereidina (Lam’k.).—Four specimens ; one is 
remarkable for its large size, the disc being 18 mm. 
across ; a second is notable for its colouration, the 
yellow (red in life) greatly predominating over the 
blue. 
Ophiocnemis marmorata (Lam’k.).—One specimen. 
Phyllacanthus imperialis (Lam’k.).—T wo specimens. 
Prionocidaris baculosa (Lam’k.).—One young specimen ; 
test 28 mm. in diameter ; primary spines handsomely 
banded with purplish-red and pale greenish-yellow. 
Echinothrix diadema (l.).—One young specimen ; test 
about 45 mm. in diameter. The colouration of this 
specimen is entirely different from that of any other 
individual of the species I have ever seen. The test 
is yellowish ; ambulacral primaries unbanded yellow- 
green ; interambulacral primaries dull reddish-purple, 
with or without pale yellow-green bands. The large 
pedicellariz and the character of the large primary 
spines show that this specimen is diadema rather 
than calamaria, but it is possibly representative of an 
undescribed species or a hybrid. 
Centrechinus savignyt (Mich.).—TIwo specimens, 4 and 40 
mm. in diameter. Both are remarkable for very 
light colouration. Test dull yellowish, with no black ; 
spines banded red or purplish-red and whitish or 
pale yellowish. The pedicellariz of the larger 
specimen are like those of savignyi, and there are 
faint lines on the upper interambulacral plates which 
may represent the characteristic blue lines of that 
species. 
38. Stomopneustes variolaris (Lam’k.).—Two specimens. 
39. Toxopneustes pileolus (Lam’k.).—T'wo specimens.
