Psilorhynchidae (Mountain carps)
Etymology: Psilorhynchus: Greek, psilos = hairless + Greek, rhyngchos = snout (Ref. 45335); hamiltoni: Named for Scottish naturalist Francis Hamilton (1762-1829), a pioneer of Indian ichthyology, who spent more than 17 years surveying the freshwater fish fauna of large areas of the Indian subcontinent.
Eponymy: Dr Francis Hamilton né Buchanan (1762–1829) was an ichthyologist and botanist who qualified as a physician at Glasgow (1783) and was to have been a ship’s surgeon, but ill- health that year prevented him taking up the post. [...] (Ref. 128868), visit book page.
