Fig. 23 Transverse section through the floor of the otic capsule of an embryo having a carapace-length of 8 mm. showing the anterior end of stapes inferior, crista basipterygoidea, and columella. X 200. side of the fenestral plate there is a wide gap between it and the stapes inferior (fig. 5). The crista basipterygoidea at this stage has grown further caudally beyond the front margin of the columella as a cylin- drical rod, and is separated sHghtly from the capsule, lying lateral to the dorsal margin of the stapes inferior (fig. 5), which has extended itself further anteriorly than in the previous stage. The stapes inferior at this stage exhibits on its inner surface a decided convexity so that it is strongly lens-shaped, but be- cause its upper margin is thinner than the fenestral plate there is left a recess between it and the fenestral plate (fig. 19)..
