	The scala tympani is shown in orange. The oval indentation in its proximal end corresponds to the fenestra cochlea (rotunda). This space extends along the cochlear duct about the same distance as the scala vestibuli, but the two do not commuinicate yet at any place. The peripheral border of the scala tympani is characterized by sacculations corresponding to spaces that are coalescing with the main space.

The peripheral border of the scala tympani is characterized by sacculations corresponding to spaces that are coalescing with the main space.

			The figures shown on this [[:File:Streeter028-30.jpg\|plate 4]] represent a series of median and lateral views of wax-plate reconstructions of the membranous labyrinth and the surrounding periotic tissue-spaces. They illustrate under the same scale of enlargement three typical stages in the development of these spaces.

Median view of same model shown in figure 28, enlarged 11.4 diameters. The scala tympani is shown in orange. The oval indentation in its proximal end corresponds to the fenestra cochlea (rotunda). This space extends along the cochlear duct about the same distance as the scala vestibuli, but the two do not commuinicate yet at any place. The peripheral border of the scala tympani is characterized by sacculations corresponding to spaces that are coalescing with the main space. The grow th of the scala is due to a coalescence of new spaces along its peripheral border rather than along its central border.
