Introduction: Primarily this note serves two purposes. The first is to record the discovery of pharmacosiderite [Fe3(AsO4)2(OH)5H2O] at Pelepah Kanan tin mine (Johore), earlier this year, and at Sungei Besi mine (Selangor) in 1970. As far as the writers are aware this species has not hitherto been recorded from Peninsular Malaysia. The second is to record and describe some unusual scorodites that were collected from Sungei Besi mine a few years ago.
