84 SPOLIA ZEYLANICA. 
investigation of the Ceylon pearl fisheries by Herdman in 
1902, therefore, not fewer than seventy-five well-authenticated 
species of echinoderms, other than holothurians, were recorded 
from the shores of Ceylon. Herdman’s collections brought 
this number up to one hundred and ten at least, of which 
fifteen are crinoids, thirty-five starfishes, twenty-five brittle- 
stars, and thirty-five echini. Still more recently the reports 
on the echinoderms in the Indian Museum at Calcutta have 
lengthened the list, Koehler adding four starfishes and nine 
brittle-stars, while A. H. Clark adds seven comatulids. A few 
species have also been added in other Papers by various 
writers, so that the recorded echinoderm fauna of the shores of 
Ceylon, excluding holothurians, and allowing for cases where 
the same species is probably listed under two different names, 
is about one hundred and thirty. The collection before me 
from Colombo adds three crinoids, four starfishes, two brittle- 
stars, and one sea-urchin. Following the list of specimens 
from the Colombo Museum, I give a revised list of the littoral 
echinoderms of Ceylon, so far as it is known at this time 
(August, 1914), excepting the holothurians. I have ignored 
this interesting class, because Dr. Pearson is himself engaged 
in preparing a complete account of its representatives in 
Ceylon. 
List of Echinoderms from Ceylon in the Colombo Museum, 
1. Comanthus* annulatum (Bell)—A number of specimens 
(22) having from 40 to 54 arms. The division series 
are nearly always 4 (3 + 4). 
2. Comanthus parvicirrum (J. Miller).—One small specimen 
with 21 arms. 
3. Comanthus samoanum, A. H. C.—One specimen with 
25 arms and 24 cirri, having 15-17 joints. 
4. Comanthus schlegelii (P. H. C.).—Two specimens, one of 
which has about 120 arms. 
* The Greek noun on which this word is based is neuter, hence 
specific names ought to use a neuter ending.
