During the late 19th century several works were published on Mexico and Central America, having had much attention of naturalist and as a result of some expeditions. One of the most extensive was the series published under the editorship of Frederick Godman and Osbert Salvin, entitled Biologia Centrali-Americana (BCA). This was a enormous work which finally comprised 63 volumes; one of them was written by Eduard von Martens on land and freshwater snails.
Although the work was issued in parts, with a date printed, the correct dates of publication are often deviating and can only be reconstructed when original wrappers are found in a library. By serendipity I found a paper by Lyal (2011) which gives the full details of all volumes, parts and plates. For convenience I reproduce here the data on the molluscan volume in BCA 9:
