America. . . . It may appear a bold, perhaps a presumptuous undertaking, 
thus to predict the discovery of species and define the characters of genera, of 
whose actual existence we have no positive knowledge; but . . . all the anal- 
ogies of nature . . . are in favor of the supposition." (OGILBy. )

* “Nella edizione del Regno animale del Cuvier, data in Inglese dal Griffith, il 
Signor Hamilton Smith distribuisce le specie dei Cervi in gruppi d'ordine inferiore, 
secondo un piano che a noi par lodevole, e che adottiamo con leggiere modificazioni." 
(Bonaparte). These modifications consist in changing the names of four of the ten 
subgenera, viz: Alce to Alces, Rangifer to Tarandus, Elaphus to Cervus, and Rusa to 
Hüippelaphus.
