Remarks. Chan and Tan (2008) described " abbasi " in the Occasional Molluscan Papers which does not fulfill the ICZN guidelines and could not be made available ( ICZN 1999 : Arts 8.6 and 11.1). However, " abbasi " was later published correctly ( ICZN 1999 : Art. 8) and made available in Chan and Tan (2010) . The authors stated that three specimens were housed in the NHM under this paratype lot, but only two are registered in the NHM collections ( Chan and Tan 2010 ).
