We report new , as yet unpublished HST/WFPC2 V , I photometry of 9 globular clusters in M31 .
These are part of a total sample of 19 clusters on M31 with well observed CMDs from HST .
The clusters have the full range of horizontal branch morphologies from blue HB to red clump , but none are found with an extreme ( blue only ) horizontal branch .
Plots of HB type vs [ Fe/H ] are similar to those of Galactic clusters , including a hint of second parameter clusters .
Sixteen halo fields adjacent to the observed clusters included in our images have been analysed .
The M31 halo metallicity distribution peaks at [ Fe/H ] =–0.7 with a tail toward low metallicity , resembling the halo of NGC 5128 ; metal rich giants appear to be centrally concentrated .
