92 SPOLIA ZEYLANIGCA. 
‘ 
comparison of one of the ‘‘ Challenger ’’ specimens 
in the M. C. Z. collection with one of Agassiz’s 
original types from Kagoshima Bay. The Ceylon 
specimens before me are notable for their large size ; 
one is 42 mm. long. They are clearly the same 
species, however, as the individual from Kagoshima. 
Littoral Echinoderms of Ceylon, excepting Holothurians. 
In the following list I give in connection with each name a 
reference to a standard work,* where synonymy and other 
details may be found. Some of the species listed by Bell, 
Déderlein, or later writers appear here under other names. A 
very few are omitted, as I am convinced the supposed records 
are based on incorrect identifications. It should be borne in 
mind that this is a list of species actually recorded from 
Ceylon. No doubt there are many others living in the 
shallow water about the Island which have not yet been seen 
by a zoologist. Some of these are already recorded from the 
Indian shores of the Gulf of Mannar. Particularly the 
comatulids and brittle-stars will prove to be as yet imperfectly 
known. Of the latter class, there are probably twice as many 
living in Ceylon waters as are here listed. The chief purpose of 
this compilation is to serve as a basis for further investigation.
