As the cleft passes backwards its lips are directed towards the vitreous in such a manner that the outer pigment layer touches the mesodermal cells which fill the gap. These mesodermal cells are continuous with the cells which form the foundation of the chorioid. They form a rather loose net-work in which lie many small blood- 1) M. NUSSBAUM, Archiv f. mikrosk.
