Fig. 6. Section through the scleral corneas of T. hamiltoni (A) and T.
pleurogramma (B). The white arrowheads indicate the beginning of the
iridescent layer (IR). In T. pleurogramma, the pigment processes can
be found on either side of the iridescent layer, whereas in T.
hamiltoni the processes are only found posterior to the iridescent layer.
The anterior scleral stroma (ASS) has divided during histological processing.
A, annular ligament; I, iris; P, pigment layer; PR, pigment reservoir with
cell bodies; PSS, posterior scleral stroma. Scale bar, 500 µm.
