100 years ago in COUNTRY LIFE
April 21, 1917
IN a communication to the French Academy of Science in February last, Mr G. A. Boulenger has drawn attention to a remarkable and unique feature presented by a small fish from Lake Mweru in Central Africa, for which he has proposed the name of Barbus pseudognathodon, which means a barbel with false teeth. Mr Boulenger now sends us a photograph of it along with a sketch showing the arrangement of the ‘teeth’. These supposed teeth are present in males only and drop off after the breeding season.
