tidens, whilst their proportions are the same as those of the giganteum 
with three denticules, but they are distinguished by the figure ( tr'efle ) 
formed by the enamel in the partially worn tooth, being different from 
the lozenge in the M. giganteum. See Cuvier’s Ossemens Fossiles, 
Divers Mastodontes, PI. II. fig. 1. 
Species 4. M. Humboldtii. This species is founded on a tooth ob¬ 
tained by M. Humboldt at Conception du Chili. This tooth is nearly 
square, and smaller than the preceding. See Cuvier’s Ossemens Fos¬ 
siles. Divers Mastodontes, PI. II. fig. 5. 
Species 5. M. parvus, founded on a tooth discovered in Europe, 
and which M. Cuvier thinks too small to be referred to any of the 
preceding species. It is represented in the Ossemens Fossiles, Divers 
Mastodontes, PI. II. fig. 11. 
Species 6. M. Tapyroides. This is founded on a tooth obtained at 
Montabusard, near Orleans. Its crown, simply indented, is not so ex¬ 
actly divided into two points, as those of the preceding species, which 
has led Cuvier to suspect that it may belong to a different species. It 
is figured in the Ossemens Fossiles, Divers Mastodontes, PI. III. fig. 6. 
Species 7. M. Arvernensis. This species was founded by M.M. 
Croizet and Jobert,Sen., upon a fragment of an upper jaw, a humerus, 
&c. found in the department of the Puy de Dome, in France.* A 
portion of the left side of the upper jaw and some separate teeth have 
since been found at Eppelsheim, not far from Alzei, in the grand 
duchy of Hessen, and are now in the museum at Darmstadt.f 
Species 8. M. latidens. This species and the following are de¬ 
scribed by Mr Clift, in the second volume of the Transactions of the 
Geological Society of London, second series. They are founded upon 
some remains collected by Mr Crawford along the course of the river 
Irawadi, between Rangoon and Ava, in Asia. The teeth in the M. 
latidens consist of “seven denticules, which are elevated, rounded, and 
mammillated, the mammillae being from three to four in number.”
