^{page 440 note 4} According to Lydekker no premolars have been seen in this species.

^{page 440 note 6} M. andium, Cuv. According to the recent researches of Burmeister, this species does not possess mandibular tusks (Sitzungsb, . Kön. Preuss. Akad. Wiss., Berlin, 1888, p. 717.)Google Scholar Hence the specimen from Mexico with such tusks, reported by Falconer, must be assigned elsewhere.

^{page 440 note 7} This species is said by Lydekker not to possess premolars. Leidy, Report U.S. Geol. Surv. Terrs. Pl., figures a tooth as a premolar, and similar specimens are not uncommon.

^{page 440 note 8} According to Lydekker, premolars have not been observed.
