144 FAUNA ANTIQUA SIVALENSIS. 



No. 201. — Fine fragment of the muzzle, broken off a little behind 

 the fossae of the canine alveoli, showing on the right side three pre- 

 molars, Avell worn. The whole tuberosity of the canine alveolus on 

 the left side, together with the empty alveoli of three incisors, are 

 present ; both broken off on the right side. Belonged to an old animal. 

 An instructive specimen, as showing the characters of the canines and 

 incisors of the upper jaw. Hard sandstone matrix. 



No. 202. — Mutilated fragment of cranium, broken off from behind 

 the right orbit, obliquely forwards to in fi-ont of left orbit and ante- 

 riorly about the middle of the muzzle constriction, showing on the right 

 side the crowns of the back molars, well worn and in tolerable pre- 

 servation. Belonged to an old animal. Hard sandstone matrix. No. 

 201 and No. 202 unite, and belong to one cranium. 



No. 203. — Fragment of cranium, comprising the iipper maxilla of 

 both sides, broken off on a level with the floor of the nasal fossa, show- 

 ing on either side the six back molars, very much worn, proving the 

 animal to have been very old. From Ava. (?) 



No. 204. — Fragment of upper maxilla, left side, .showing the two 

 last premolars and three true molars in situ ; the last molar is a little 

 worn, showing the characteristic trefoil discs of wear. Half of palate 

 also shown. Some ferruginous coloured matrix on the palate like the 

 Ava specimens. 



No. 205. — Superior maxilla, right side, containing the five pos- 

 terior teeth in situ of a very old animal. Specimen much mutilated. 



No. 206. — Fine specimen of the cranium, broken off in front about 

 the middle of the facial portion, showing the occiput nearly entire, as 

 also the prominent edge of the occipital and sagittal crests ; the two 

 zygomatic arches and temporal fossie, together Avith both orbits, tlie 

 right nearly entire : the teeth all broken off, and the spheno-palatine 

 region with occipital condyles wholly abraded by attrition. Hard 

 sandstone matrix in the temporal fossa; and orbits, the most perfect 

 specimen in the collection, so far as regards the strictly cranial charac- 

 ters of the head. 



No. 207. — Fine specimen comprising the greater part of the lower 

 jaw, both sides, in two pieces. The left ramus containing aU the 

 molars, except the anterior premolar, Avhich had dropped out ; the right 

 containing the anterior premolar and the next five teeth, the last true 

 molar alone being wanting. The chin portion is perfect to the border 

 of the incisive alveoli. The two canines are present, broken off only at 

 their tips, and presenting the discs of wear on their posterior surface. 

 The six incisors are also present, perfect nearly to their tips ; they 

 emerge nearly horizontally, the outer being a little lower, and they are 

 subequal in size. The left ramus shows the last three true molars, of 

 which the anterior is much worn, the penultimate less so, and the last 

 barely touched ; the premolars are all broken off, except one. On the 

 right side the base of the anterior premolar is in situ, with but a very 

 short interval between it and the canine, not much exceeding that 

 between it and the second premolar; the body of this tooth is broken
