?Hast Indies, — The type of Carpenter’s Actinometra 
schlegelii proves to be a typical specimen of the species 
described in the »Challenger” Report as Actinometra du- 
plex, Actinometra nobilis, and Actinometra regalis, three 
nominal species the identity of which I had discovered 
during a visit to the British Museum just before coming 
to Leyden. The type specimen appears to have had four 
cirri of which the first two segments still remain; there 
are numerous more or less obsolete cirrus-sockets. This isa 
common condition in this species; specimens are found with 
no cirri at all and with the centrodorsal very small and stel- 
late, or there may be as many as a dozen; usually there 
are from one to four or five. Of the IIIBr series those on 
two rays are typical, 2 externally, 4(3- 4). internally; 
on a third ray one of the external series is 2, but the 
other three series are 4(3-+ 4); on the remaining two 
rays all the series are 4(3 + 4). The other division series
