THE ECHINODERMS OF CEYLON. 91 
Tripneustes gratilla (L.).—T'wo specimens. 
Temnopleurus toreumaticus (Leske).—One specimen. 
Gymnechinus robillardi (De Lor.)—One fine specimen, 
28 mm. in diameter. 
Salmacis bicolor, Agass.—Six fine specimens. 
Salmacis virgulata, Agass. & Des.—Fourteen specimens. 
Pseudoboletia maculata, Trosch.—Four specimens. Al- 
though these individuals have the conspicuous dark 
blotches of maculata, the buccal plates are large and 
close together, as is supposed to be characteristic of 
indiana. Probably the two species are not distinct. 
Echinostrephus molare (Bl.)—One specimen. 
Echinometra mathzi (Bl.).—One small green specimen. 
Clypeaster humilis (Leske).—Seven specimens. 
Laganum depressum, Agass.—Two specimens. 
Fibularia volva, Agass. & Des.—One bare test, re- 
markable for the size and form of the ambulacral 
pores. These are not only conspicuously large, but 
are distinctly triangular in outline instead of circular. 
This is particularly true of those in the outer part of 
the posterior petals. There are altogether more than 
70 such pores.. The specimen was found in the 
stomach of a large starfish, Luidia maculata, M. & T. 
Echinodiscus auritus, Leske.—Seven specimens. 
Echinolampas alexandri, De Lor.—Six specimens. 
Echinolampas ovata (Leske).—Four specimens. 
Lovenia elongata (Gray).—Nineteen specimens, mostly 
young. 
Pseudomaretia alta (A. Ag.).—Three specimens. I think 
there is no doubt Koehler is right in separating this 
species from Maretia. The difficulty with the 
“ Challenger * report figures, to which De Loriol, 
De Meijere, and Koehler refer, is due to the fact that 
the specimen there figured is not Maretia alta, but 
appears to be quite a distinct, though superficially 
very similar, species. This statement is based on a
