Three treatises published during the 19^th Century summarized the non — marine molluscan fauna of Mexico and Central America known at that time.

Herman Strebel. 1873. Beitrag zur Kenntniss der Fauna mexikanischer Land — und Süsswasser — Conchylien. Theil I: 1 — 69. 1875, Theil II: 1 — 58. 1878, Theil III: 1 — 53. 1880, Theil IV: 1 — 122. 1882, Theil V: 1 — 144.

P. Fischer & H. Crosse, 1870 — 1878. Mission Scientifique au Mexique et dans L’Amerique Centrale. Études sur les mollusques terrestres et fluviatiles du Mexique et du Guatemala; Part I: 1 — 702. 1880 — 1902. Part II: 1 — 731.

Eduard von Martens, 1890 — 1902. Biologia Centrali — Americana. Mollusca. 1 — 706.

J. Diáz de León (1912) compiled a list of mollusks recorded from Mexico at that time.

Von Martens (1890 — 1902) gives complete references and citations for all taxa THEN known from Mexico and Central America. Therefore many 19^th Century citations are omitted from this list as redundant. Citations to first publication of generic, specific and subspecific names include the publication in which the name first appeared. In the cases of the major works by Fischer and Crosse (1970 — 1902), Strebel (1873 — 1882), Von Martens (1890 — 1901), Bequaert & Miller (1973), and Pérez & López(2002), only the date, page and figure citations are included because they are general works, and no other publications by these authors conflict with these citations.

The bibliography includes citations of works dealing with geographic regions other than the study area. They are included because they contain information relevant to the Mexico — Central America fauna.
