of first plate at the middle, "8 in. ; of second, - 95 in. ; of third plate, - 85 in. ; of 

 fourth, -75 in. ; of fifth, -7 in. ; of sixth, -6 in. ; of seventh, *o in. 



Fig. 8. — Elephas planifrons. A very fine and characteristic speci- 

 men of the last upper molar, right side. Was found in contact with 

 the lower jaw specimen, fig. 9. Shows about eight or nine ridges and 

 a heel ; the three first ridges worn out. The enamel is very thick, 

 with irregular lozenge-shaped expansion, and a loop in the middle. The 

 plates stand high in relief from the cement. The denticles are very 

 few and thick, the last ridge showing only three crown plates very low, 

 the last being but 2^ inches high. — B.M. 



Length of molar, 10* in. Width of crown, 35 in. Height behind, 2 - 5 in. 



Fig. 9. — Elephas planifrons. Last lower molar, right side. Is very 

 valuable from having been found in contact with the upper molar 

 (fig. 8). Shows only eight ridges and a heel. The plates are very 

 thick and low. The sixth ridge shows only four denticles. In this 

 and the last figure the discs of wear form transverse bands, which are 

 broader, fewer in number, and wider apart than in the Indian Elephant ; 

 the bounding edges of enamel are sometimes nearly parallel ; in other 

 cases they show a slight angidar expansion, or throw out a salient loop 

 (or outlying) tubercle near the middle. — B.M. 



Length of molar, 9'5 in. Width of crown, 3 - 5. Height of crown at sixth 

 ridge, 3" in. 



Fig. 10. — Elephas planifrons. Fragment of lower jaw, with ante- 

 penultimate and penultimate milk teeth in situ. 1 -* — B.M.

 nated E. Hysudricus, hut this is doubt- ridionalis on plate. The error is corrected 

 less an error, as the figure is referred to | in Dr. E.'s handwriting in the copy of
