Phase-contrast light micrograph of the (wet) AP tectorium of Bufo marinus, the cane toad. The arrow points to the tectorial curtain. The tectorial corner was adjacent to the caudo-lateral end of the curtain, above and to the right of the arrowhead. Again, the tissue was observed here surrounded by buffer solution in a depression slide, covered by a thin coverslip. For similar views of two Eluetherodactylus AP tectoria, see Figure 8 from Lewis, Hecht, Narins 1992.
