Plate LVII. 



Fig. 1. — Hippopotamus (Tetraprotodon) Palceindicus. (Falc. and 

 Caut.) Almost entire skull, viewed from above, with zygomatic arches 

 complete. Specimen from the Nerbudda in B.M. It shows well the 

 great saliency of the sagittal crest. There is a finer specimen in the 

 Museum of the Asiatic Society of Bengal. 



Fig. 1 a. — Lateral view of same skull, showing cavity of orbit, &c. 

 The great projection of the orbit above the plane of the frontal, charac- 

 teristic of the species, is well seen. 



Fig. 1 b. — Same skull, palatine view, showing three molars, the fur- 

 thest back intact, the two next ground down ; also the three premolars 

 on one side, and two on the other. 



Fig. 1 c. — Occipital view of same skull, showing condyles and 

 foramen magnum, and the great saliency of the occipital crest. 



Figs. 2 and 2 a. — H. Palceindicus. Portion of upper jaw, right side, 

 with three molars. — B.M. 



Figs. 3 and 3 a. — H. Palceindicus. Portion of lower jaw, with 

 teeth. — B.M. 



Fig. 4. — H. Palceindicus. Fragment of canine. — B.M. 



Figs. 5 and 5 a. — H. Palceindicus. Anterior portion of jaw with 

 alveoli of four incisors. The diameter of the alveoli of the central in- 

 cisors is much less than that of the external incisors — a fact which 

 refutes De Blainville's opinion that the Nerbudda Tetaprotodon is 

 identical with the living African species. In the latter the middle in- 

 cisors are the largest. 



Figs. G and 6 a. — //. Palceindicus. Portion of lower jaw, with 

 grinders (three molars and two premolars) worn down. — B.M. 



Figs. 7 and 7 a. — //. Palmndicus. Portion of lower jaw, with 

 two molars. — B.M.
