* For date see Engelmann's Bibliography, p. 10. The genus /tale/us is usually 
attributed to Sparrman (K. Vetensk. Acad. Handl. Stockholm, XX XVIII, 147-150, 
Apr.-June, 1777), but Viverra ratel is the only name there used. Sparrman's animal 
came from the Cape of Good Hope, Bennett's specimen ‘from Madras, whither it 
was brought from the interior." 
T Rattus Zimmermann, 1777 (Specimen Zool. Geog. Quad., 344—547) is not generally 
regarded as a valid generic name.
