# Canna Maria Louise Popta

Canna Maria Louise Popta (31 May 1860 – 13 June 1929) was a Dutch biologist.
Born in Breda, Popta was one of the first women to enrol as a student at Leiden University where she studied for a degree in geology, zoology and botany, allowing her to teach in high schools. She studied for her doctorate at the University of Berne under the supervision of Eduard Fischer, her thesis was on the Hemiasci, a fungal group which was then thought to be the link between the Phycomycetes and Ascomycota. She lao wrote an 1897 article about fungi on sugar cane. After completing her doctorate she obtained a position at the Rijksmuseum van Natuurlijke Historie in Leiden as a Lab Assistant to the curator of reptiles, amphibians and fishes. During her career at the museum she concentrated mainly on ichthyology, eventually retiring in 1928, and dying the following year in Leiden. She wrote over 40 scientific papers and a number of articles for encyclopedias. For example, she wrote a final compilation of the freshwater fish collected in central Borneo, describing a fish fauna of 173 species from the Kapuas and 97 species from the Mahakam. She also tried to complete and publish Bleeker's Atlas Ichthyologique des Indes Orientales néerlandaises but this was halted due to economic difficulties, the plates eventually being published in 1983 but by then the text was considered to be too out of date to be published. She seems to have had a difficult time at the museum and often appeared to be in conflict with and not highly regarded by the two directors she worked under, Jentink and E.D. van Oort, and there are some indications that she may have suffered from mental ill health. Popta never married and lived with, and cared for her sister, who was said to be disabled. Despite the supposedly difficult relationship she had with Jentink she named the cyprinid Diplocheilichthys jentinkii in his honour for making specimens available for Popta to study.

## Taxa

Among the taxa first described by Popta are the fishes Tetraodon hilgendorfii, Pangasius nieuwenhuisii, Dotsugobius bleekeri and Osteochilus bellus. She also named the goby genera Cryptocentroides. and Pseudogobius.
Poptella a genus of Characins was named for Popta who described Tetragonopterus longipinnis in 1901 and donated one of the type specimens to Carl H. Eigenmann’s collection at Indiana University, Eigenmann subsequently described the new genus Poptella in 1908. The fish species Trichopodus poptae, Adrianichthys poptae and the Marianas rockskipper (Praealticus poptae) are among those to have their specific names referring to and honouring Canna M. L. Popta.
