It is revealed that the alignments of the membrane pores alter the vesicle shapes and the types of shape transitions for the genus $g \ge 3$. At a high reduced volume, a stomatocyte with a circular alignment of $g+1$ pores continuously transforms into a discocyte with a line of $g$ pores with increasing intrinsic area difference. In contrast, at a low volume, a stomatocyte transforms into a ($g+1$)-hedral shape and subsequently exhibits a discrete phase transition to a discocyte. %U http://arxiv.org/abs/1510.01424v2
