The overall geometry of the shape spaces
, has been studied in [2,4], while the riemannian metric for each
, is given in [5]. The aim of this paper is to explore the geodesic geometry of
, especially when 2
m
k1. One of the main results is the identification of the cut-locus for each non-singular point in
. We also obtain an extension of Casson's theorem concerning
.
