Julien François Desjardins was a French zoologist. He studied in Parish from 1822 to 1824 under Cuvier, and was influenced by Louis Jacques Thénard, Joseph Louis Gay-Lussac, Pierre André Latreille, René Desfontaines and others. He embarked on a career in civil engineering, but soon realised that he should return to his original passion of natural history and studied at the Muséum d'Histoire Naturelle.
With Charles Telfair, Wenceslas Bojer, and Jacques Delisse, Desjardins took part in founding the Société d'Histoire Naturelle de l'Île Maurice on 11 August 1829. He was the first secretary of this Society and editor of the publication Rapport annuel sur les travaux de la Société d'histoire naturelle de l'Île Maurice until 1839, when he left for France to publish his observations. His premature death led to the acquisition of his manuscript by Félix Édouard Guérin-Méneville, who never published it. An excerpt from the Proceedings of the Zoological Society of London of a meeting held on 23 October 1838 reads:
A letter was read from M. Julien Desjardins, Secretary of the Natural History Society of Mauritius, stating that it was his intention to leave that island on 1 January 1839 for England, with a large collection of objects in natural history, many of which he intended for the Society.
Desjardins made a thorough search for fossils in his home region of Flacq, and found fragments of the osseous cover and humerus bones of endemic tortoises. At Plaine des Roches and at Montagne Blanche, he found them scattered on the surface. At Mare La Chaux and Riche Mare, they occurred in mud and shallow water.
L'Ichthyologie à l'Île Maurice de 1829 à 1846 lists 28 species with the specific name desjardinsii.

Edward Blyth was an English zoologist who worked for most of his life in India as a curator of zoology at the museum of the Asiatic Society of India in Calcutta. In 1841 he travelled to India to become the curator of the museum of the Royal Asiatic Society of Bengal. He set about updating the museum's catalogues, publishing a Catalogue of the Birds of the Asiatic Society in 1849. He remained as curator until 1862, when ill-health forced his return to England. His Natural History of the Cranes was published posthumously in 1881. Avian species bearing his name include Blyth's hornbill, Blyth's leaf warbler, Blyth's hawk-eagle, Blyth's olive bulbul, Blyth's parakeet, Blyth's frogmouth, Blyth's reed warbler, Blyth's rosefinch, Blyth's shrike-babbler, Blyth's tragopan, Blyth's pipit and Blyth's kingfisher.
