Abstract
Francis de Castelnau (b.1802–d.1880) was a widely travelled explorer and diplomat, and one of the most prolific naturalists of the 19th century, best known for his papers on fishes and beetles (the latter published under the name Laporte). As an ichthyologist, Castelnau was prolific, taking advantage of his various diplomatic postings in Brazil, Cape Town, Bangkok, Melbourne, and Sydney to collect and describe fishes. Over his lifetime, he published 21 papers and monographs, and described 461 new species of marine and freshwater fishes. During his time as French Consul in Melbourne (1862–1876) and Sydney (1877), Castelnau personally collected, or had sent to him, collections of fishes from all parts of Australia and from New Caledonia (herein referred to collectively as his Australian fishes). In a series of 19 papers published between 1872–1879 Castelnau described 62 new genera and 276 new species of Australian fishes (including a hoax species, Ompax spatuloides Castelnau 1879). The bulk of these collections were sent to the Muséum national d’Histoire naturelle, Paris, with only a few deposited in Australia: in the Melbourne Museum, the Australian Museum, Sydney, and Macleay Museum [now Chau Chak Wing Museum], University of Sydney. Because of the dispersed nature of Castelnau’s Australian fish collections and their age and condition, with many specimens lost or destroyed, they have been difficult to study. Castelnau’s descriptions were often inadequate and very few species were illustrated, compounding the problems in correctly identifying many of the fishes he described. The recent discovery of his paintings and sketches of fishes in the Melbourne Museum, however, has made it possible to identify and determine the taxonomic validity of many of the Australian fishes he described. This paper re-examines Castelnau’s Australian fish collections in Paris, Melbourne and Sydney, and presents for the first time his previously unpublished paintings.
