typical species of Himerometra; that is, according to Car- 
penter’s classification it falls in the »Savignyi-group”’ of 
» Antedon”, and is not an »Actinometra” at all! All the 
IIIBr series are 4(3 + 4). The proximal pinnules are very 
large and stout, the tips ending bluntly after a consider- 
able recurve. So far as they are preserved the segments 
are broader than long; the distal ends are not thickened 
or produced, though appearing slightly prominent and a 
trifle swollen. One P, with eighteen segments appears to 
be complete. 
This appears to be the species, common at Singapore, 
which I have referred to as Himerometra crassipinna (Hart- 
laub), but the identification cannot be considered as certain 
on account of the absence of the cirri and of most of the 
pinnule tips.
