Summary: A new analysis of the violet amphibole from the original locality where winchite came from agrees with another recent analysis in differing substantially from the original winchite composition and is (K_0·17Na_2·10Ca_0·23)(Al_0·19Ti_0·00Fe³_1·27Fe²_0·01Mn_0·07Mg_3·34)Si_8·01O_22·05(OH)_1·95. It is essentially a magnesio-arfvedsonite. Although it is possible that the original analysis was unreliable, evidence is given to support the alternative view that there is a wide range of blue alkali and soda calcic amphibole compositions at Kajlidongri and the name winchite should be restricted to compositions between ferri-winchite CaNaMg₅Fe³⁺Si₈O₂₂(OH,F,Cl)₂ and alumino-winchite CaNaMg₅Al Si₈O₂₂(OH,F,Cl)₂. X-ray, density, and optical data on the analysed mineral are given.
