Name

Tetronarce Gill, 1862

• Type species: Torpedo occidentalis Storer, 1843

Etymology: tetra- (= four), referring, according to Gill (1895), to “four-sided form” of T. occidentalis (= nobiliana), perhaps an allusion to how the ray’s disc (two pectoral fins) and two pelvic fins appear as four sides (or lobes) when seen from above (Marcelo R. de Carvalho, pers. comm.); narce, from narke (= numbness), an ancient Greek word used for any electric fish, based on their ability to cause a numbing sensation [Gill attempted to change spelling to Tetranarke in 1895, saying Tetronarke was “purely a printer’s blunder,” but original spelling is retained].
