[VIII-9] Brasseur de Bourbourg, Palenqué, p. 33. 'Chalchiuhcuecan, ou le pays des coquilles vertes. On voit encore des débris de la ville de ce nom, sous les eaux qui s'étendent de la ville de la Véra Cruz au château de San-Juan-de-Ulloa.' Id., Hist. Nat. Civ., tom. i., p. 143. Ruins of the ordinary type are reported outside the triangular area, in the Sierra de Matlaquiahuitl or del Gallego, running south from the Rio Jamapa to San Juan de la Punta. Sartorius, in Soc. Mex.

[VIII-16] Esteva, in Museo Mex., tom. ii., pp. 465-7, with plan and view. Respecting the circumference of the structure, Esteva's text says: 'la media circunferencia de la base, tomada desde el escalon ó cuerpo A. B. C., (letters which do not appear in his plate) pues mas abajo no se podia tomar con esactitud, es de ciento cincuenta y seis piés castellanos.' I have taken the circumference from the plan. The material Esteva states to be 'cal, arena, y piedras grandes del rio,' but the view indicates that hewn stone is employed, or at least that the whole structure is covered with a smooth coating of cement in perfect preservation. Esteva's account is also published in the Diccionario Univ. de Geog., tom. x., pp. 166-8, and a slight description from the same source in Mayer's Mex. Aztec, etc., vol. ii., pp. 203-4.

[VIII-18] Iberri, in Museo Mex., tom. iii., p. 23. Gondra's account in Mosaico Mex., tom. ii., pp. 368-72, with two views and a plan. Sartorius' description in Soc. Mex. Geog., Boletin, 2da época, tom. i., pp. 821-2, tom. ii., p. 148, with two views apparently the same as by Gondra, an additional side and front view of a pyramid, and a plan which bears no likeness to Gondra's, representing perhaps a different part of the ruins. According to this author the ruins were first made known in 1829 or 1830. The two accounts are very perplexing to the student, sometimes resembling each other so closely that one is ready to believe that Sartorius was the explorer from whom Gondra obtained his information and drawings, in other parts so different as to indicate that different ruins are referred to. I am inclined to believe that Gondra's information did in part refer to some other ruin in the same region. Gondra's account is also printed in Diccionario Univ. Geog., tom. ix., pp. 565-8. Brief mention in Rivera, Hist. Jalapa, Mex. 1869, tom. i., pp. 389-90.
