MOLAE TEETH AND OTHER REMAINS OF MAMMALIA. 
On the anterior and posterior surfaces of the teeth there is a semi-vertical 
fold or ridge of enamel, looking like the commencement of a cingulum ; on the 
external surface the form of the teeth is similar to that of the tooth of Cervus 
triplidens described above. The enamel is slightly rugose. The measurements of 
the specimen are given below 
In. 
Length of two molars ... ... ... ... ... 1*7 
Length of last molar ... ... ... ... ... 0*9 
Width of ditto ... ... ... ... ... 0'9 
The teeth are distinguished from those of Cervus triplidens by the small size 
of the accessory tubercle and its position far within the median valley, by the 
squareness of the crown, and by the smaller obliquity of the external halves of the 
barrels to the antero-posterior axis of the tooth. 
The present molars approach somewhat in general form to those of the living 
Mucervus duvaucellii ; they are, however, distinguished by the smaller degree of 
obliquity of the outer surfaces of the barrels to one another^ and to the antero- 
posterior axis of the tooth ; they are also distinguished by the presence of the 
enamel folds on the anterior and posterior surfaces. 
Genus Listriodon, jH. von Meyer. 
The occurrence of this genus in the Indian Tertiaries was first announced by 
me in my paper on Indian Fossil Mammalia (“ Rec. Geol. Surv., Ind., vol. ZX, 
pt. 3) ; the specimens on which this identification was made are now for the first 
time figured and described ; the genus was originally founded on specimens of the 
molars from the Molasse of Switzerland ; a description of these teeth is given in 
Dunker’s “ Palseontographica” (1874, page and plate VII, fig. 71). The first 
of the Indian specimens is the same as that referred by Falconer to the genus 
Tapiriis (“ Ral. Mem.fi vol. I, p. 415), and to which he assigned the name of Tapirus 
pentapotamice : on the authority of this specimen the genus Tapirus is introduced 
by Mr. Wallace among the Fossil Siwalik Mammalia.* 
The second specimen was brought from the Siwaliks of the Panjab by 
Mr. Theobald, and was, from its similarity to Falconer’s wrongly-named specimen, at 
first referred by me to Tapirus. The only fossil from India that has been described 
as Tapirus, besides the above, is a portion of the symphysis of a mandible from 
Burma {Clift : ‘‘ Trans. Geol. Soc., Lon.fi Sec. Ser., vol. II) ; this may very probably 
have belonged to the present genus. 
Listriodon pentapotamijd, Falc. sp. PI. 8, figs. 8, 9. 
The first of the two specimens {fig. 8) is the above-mentioned specimen of 
Falconer’s (now in the Indian Museum) from the Tertiary beds of Kushalghar near 
( 70 )
