known to liavc been tbe case. The specimen from which this interesting dis¬ 
covery was made consists of a portion of a left maxilla containing a single tooth 
in use which can-ies foiu- ridges and which measures 3| inches in length. 
Above tbe base of this tooth the broken jaw shews a complete germ of a pre¬ 
molar, which I have removed from its matrix: the germ is oval in shape, and 
carries only two ridges, and fore-and-aft talons. Since the larger tooth is situated 
below a premolar, it is clear that the former is a milk-molar, and since it carries 
four ridges, that it is the last or third tooth of that series. I cannot, of course, 
say whether the penultimate milk-molar of M. latidens was succeeded by a pre¬ 
molar, but not unprobably such was also the case. 
Genus: Stegodon. 
Stegodon clifiii. 
This species was originally named upon the evidence of teeth obtained solely 
from Ava and Eurma, and I cannot find more than one recorded instance of 
its having been obtained beyond those countries. This instance occurs in the 
catalogue of the fossil vertebrata of the Asiatic Society of Bengal,’ where a 
portion of a mandible of 8- cliftii (No. is stated to have been obtained from the 
Siwaliks. In the table of the species of Mastodon and Elephant given on page 14 
of the second volume of the “ Pateontological Memoirs,” the distribution of this 
species, like that of Mastodon latidens, is given as “ Southern India and Ava 
now, the latter species is well known as occurring in the Siwaliks, and “ Southern 
India” may be a misprint for Siwaliks ; on the other hand, Southern India is 
given as the locality of M. panddonis which was obtained from the Deccan, and it 
is possible that M. latidens and 8. cliftii have also been obtained from the Deccan : 
if so, however, all record of this has been lost; on this supposition the word 
“ Siwaliks ” is omitted from the distribution of M. latidens. All the specimens of 
8. cliftii figured in the “ Fauna Antiqua Sivalensis ” of which the locality is given, 
were obtained from Ava and Burma, and therefore the only recorded instance of 
the species occurring in the Siwaliks is the above-mentioned lower jaw. 
The distribution of this species being so uncertain, it is a matter of some in¬ 
terest that I am now able to state clearly that the species does occur in the 
Siwaliks. I am not aware that any specimens of 8tegodon cliftii have hitherto 
been recorded as having been found in the Sub-Himalayan Siwaliks. 
Two specimens of molars of a 8tegodcm sent by Mr. Theobald seem undoubtedly 
to belong to this species : the first specimen is a portion of the (probably) first upiier 
true molar; it carries five complete transverse ridges, a sixth having been broken 
away. In the number of ridg'es the tooth agrees with the fiist molar of 8. cliftii; 
it differs from the corre.sponding tooth of 8. insignis by having six, in place of 
seven ridges, and by being wider, and by the more open valleys: it is also much 
wider, and the valleys are more open than in the tooth which 1 refer below to 
8. homhifrons, though that tooth also contains six ridges. The second specimen 
is a right ramus of the mandible containing the ultimate true molar: this tooth 
agrees in general eharacter with the coiresponding tooth of 8. clifiii represented
