36 FAUNA ANTIQUA SIVALENSIS. 



Length of back molar. 9 - 7 in. Width, 3 - 8 in. Width of palate in front. 2* in. 

 Width behind, 2-8 in. 



Figs. 2, 2 a, and 2 b. — Eleplias insignis. Small broken head. This 

 is a very remarkable specimen. The teeth, although small, are assuredly 

 the first and second true molars. The front tooth has six ridges and a 

 heel ; the penultimate has only seven ridges and a large heel, -with a 

 distinct talon in front ; all the ridges of the front tooth worn ; very 

 little cement ; plates deep. The tusks, if any, have drojiped out ; two 

 large sub-orbitary foramina. — B.M. 



Extreme length of skull, 18' in. Length of incisives, 15'8 in. Width between 

 orbits measured to lachrymal tubercle, 7'8 in. Contraction of muzzle at suborbi- 

 taries, 11*9 in. Width of muzzle at tip, 9 - 2 in. Width between outer surfaces of 

 maxillaries at the back molar (beginning), 8"4 in. Length from diasteme to tip of 

 tusk-sheaths, 9 - 3 in. Depth from pterygoid to front, 14 - 7 in. Length of anterior 

 molar, 4-9 in. Width, 2'7 in. Width of palate between front molars anteriorly, 

 1*5 in. Ditto behind, 22 in. Length of penultimate molar, 7"4 in. Width, 

 3" in. 



Figs. 3 and 3 a. — E. insignis. Lower jaw, with first and second 

 true molars. Five ridges remaining of front molar ; other molar has 

 twelve main ridges and a heel. Besides the characters shown in the 

 figure, the diastemal portion is very much flattened in front of the an- 

 terior molar. This remarkable specimen is in the Museum of the Col- 

 lege of Surgeons ; the drawing is taken front a cast. 



Extreme length of fragment of jaw, 24* in. Height to alveolus, 9 - in. Width 

 of jaw in front, 4 - 8 in. Width behind, 7'5 in. Length of ascending ramus, 12-8 

 in. Length of front molar, 5 - in. Width, 3'5 in. Length of last molar, 11*5 in. 

 Width, 4- in. 



Figs. 4 and 4 a. — Elephas Namadicus (Falc. and Caut.). From the 

 Nerbudda. Small head Avith two molars in situ; one Avorn, but the back 

 one in germ ; probably the first and second true molars. The right 

 tusk is present ; is very large for size of head ; is nearly circular in 

 outline, and diverges greatly in front. The tusk-sheaths are long, as in 

 E. Indicus and E. primigenius. The brow -ridge, &c, are exactly as 

 in the large head of E. Namadicus (Plate XII. A.). The space between 

 the tusk-sheaths is very shallow, as in E. plamfrons. Is probably a 

 young male head. — B.M. 



Extreme length from broken occiput to broken incisive, 29 - in. From groove of 

 brow to tip of nasals, 6 - l in. Across nasal opening, 12-5 in. Height of nasal 

 opening at sides, 3'6 in. Width of muzzle (incisive sheaths) at orbital foramen, 

 13 - in. From top of incisive sheath at fissure to diasteme, 9 - 8 in. Anteroposte- 

 rior diameter of left orbit, 59 in. Transverse diameter of right tusk, 3 - 6 in.; ver- 

 tical, nearly the same. Width of palate in front, 1*6 in. Width of palate behind, 

 2-7 in. Width of front tooth, 2-6 in. 



Plate XXV. 



Figs. 1 and 1 a. — Eleplias Ganesa. Lower jaw, Avith last lower 

 molar. SIioavs tAvo mentary foramina on either side ; is very sharp in 



last tooth has ten ridges, or nine and a 

 large heel ; only the two front ridges 

 are worn ; the tooth is very convex from 



Length of anterior molar, 4-5 in. 

 Width, 4 - in. Length of last molar (very 

 much curved), 10 - 4 in. Greatest width, 



back to front, and the ridges are very j 3 - 9 in. Interval between front teeth, 

 high and convex across, with a large | T9 in. Interval behind at niche of 

 quantity of cement. Looks very like (!) '■ palate, 4.5 in.
