(3)On the basis of recent information, the Scientific Review Group has concluded that the conservation status of certain additional species listed in Annexes A and B to Regulation (EC) No 338/97 will be seriously jeopardised if their introduction into the Union from certain countries of origin is not suspended. The introduction of the following new species should therefore be suspended: Hippopotamus amphibius from Cameroon and Mozambique; Cercopithecus dryas from the Democratic Republic of the Congo; Stephanoaetus coronatus and Torgos tracheliotus from Tanzania; Balearica pavonina from Sudan; Chamaeleo africanus from Niger; Heosemys annandalii and Heosemys grandis from Laos; Mantella pulchra from Madagascar; Tridacna crocea , Tridacna maxima and Tridacna squamosa from Cambodia; Nardostachys grandiflora from Nepal.
