FAUNA ANTIQUA SIVALENSIS. 



No mark. There is some sandy matrix sparingly covering the 

 fossil, not like the ordinary Perim matrix. But the characters of the 

 tooth are entirely those of Mastodon latidens ; a yoimger tooth closely 

 resembling it contained in the Scinde collection, No. 2. 



D. From Scinde. 



No. 1. Mastodon latidens. — Fragment of large upper (?) molar, 

 comprising two ridges, little touched by wear. The only complete 

 iurrow present is transverse without interruption, as in the Ava speci- 

 mens. The longitudinal bisecting cleft is very distinct. The weathered 

 appearance is peculiar, differing from anything else in the collection. 

 The teeth appear to have been embedded in a yellowish clay. 



No. 2. Mastodon latidens. — Third milk molar, lower jaw, left side (?), 

 showing the posterior two and a half ridges and the heel, all well 

 worn. The two last ridges are supported on a large fang. The an- 

 terior, with the whole of the first and half of the second ridge, are 

 broken oiF. The valleys are transverse, without interruption. Vide 

 Perim Island specimen, No. 103. 



No. 3. Mastodon latidens. — Portion of a second milk molar, show- 

 ing two ridges and a low talon ridge supported on one fang. The 

 valley very open. Foimd in a low range of sandstone breccia, com- 

 posed of angular pieces of nummulitic limestone cemented with clay, at 

 Sehwan on the north side of the Jukkeo Hills. 



HI. — Mastodon (Triloph.) Pandionis.^ Description by Dr. Falconer 

 OF Fossil Molars from the Deccan, presented by Colonel 

 Sykes to the India House Collection. 



(Extracied from Note-book: 2ith December, 1856.) 



No. 1. — The principal piece is a penultimate molar, upper jaw, 

 left side : so determined fi-om comparison with a germ specimen from 

 M. Lartet of an antepenultimate. The crown of the tooth is perfectly 

 entire, the front ridge alone being a little touched by wear on the 

 inner side ; but the fangs and base of the tooth are broken off right 

 across on a line with the termination of the enamel shell. It exhibits 

 three well-defined ridges, with a thick strong front talon, and a hind 

 talon confluent with the last ridge. It is a true and immistakeable 

 Trilophodon — the only one yet yielded by India, and very different in 

 its crown characters from all the Sewalik, Ava, or other fossil Mas- 

 todons of the East. 



The general form of the crown resembles very strongly that of 

 Triloph. angustidens, the principal difference being that the ' col ' of 

 vallecular flanking mammillEe is still more developed than in that 

 species. The crown is traversed, as usual, by an indistinct longitudinal 

 cleft along the axis, marking off an outer and inner division. Each of 

 the three ridges has the outer division simple and composed of a thick 



■ Dr. Falconer described the first 

 specimen as belonging to a new species, 

 Mastodon Andara7ivs. (From Pliny, 

 Nat. Hist. vi. cap. 19, ' Validior deinde 

 gens Andaree phirimis vicis, &c. The 

 ' Aiidhra' race of kings (Wilson), soutli 



of Godavery.) 



The second, he regarded as identical 

 with a specimen of M. Pandionis in the 

 collection of M. Lartet, and its descrip- 

 tion is headed Mast. Atidaraiius, nunc 

 M. Pandionis. — [Ed.]
