MAMMALIA PACHYDERM ATA . 49 



or to the phytophagous Cetacea, has at length been decided, since together 

 with a portion of the jaw and teeth, a femur has been found in New Holland, 

 which, with the two former, has been recognized by Owen as belonging to 

 Dinothcfium (Ann. xi, pp. 7, 329). It must be referred to the proboscidian 

 Pachydermata. 



With respect to Kaup's ' Remarks on the three species of Mastodon 

 and the three species of Tetracaulodon of Is. Hays,' as they were published 

 in our 'Archives,' p. 168, I need here only refer to that place. 



Lyell has communicated his observations (Ann. Nat. Hist, xii, p. 125) 

 on the geoguostic relations attending the deposit of the Mastodon gigameum, 

 and other fossil remains, at the Bigbono-lick in Kentucky, and at other 

 localities of the United States. 



From microscopic examination of the tusks of Mastodon giyanteum, Tetra - 

 caulodim Godmani, Kocliii and tapiroides, and of the Missuriiim, Nasmyth 

 (Ann. of Nat. Hist, xi, p. 502) has ascertained the existence of differences 

 in all, he will not, however, decide whether these differences are specific, 

 or only individual. Upon this Hays remarks, that each tusk of the Missitri-uni 

 was made up of three pieces, and that it was by no means certain that they 

 had all belonged to the same animal, on which account each portion should 

 have been examined separately by Nasmyth. (Proceed, of the Americ. Phil. 

 Soc. 1843, vol. ii, p. 265.) 



The native locality of the Rhinoceros cuculatiis described by me, has been 

 ascertained by Harris and Dr. Roth, to be in Southern Abyssinia, as I 

 supposed. (Harris, the Highlands of ^Ethiopia, ii, p. 425.) 



Of the species of Hog of the Indian Archipelago, there have been figured, 

 in the ' Nedeii. Verhandel.' Sus timoriensis, tab. 31, figs. 1-3, Sits barbaft'x, 

 figs. 4, 5 (cranium), S. vittatus, tab. 29, S. cclebensis, tab. 28, S. vemtcosus, 

 tab. 28, S. barbatus, tab. 30. 



The Tapinis viUosus (Tapir Pinchaque) lias lately been 

 again observed by Goudot. (Instit. p. 44.) 



He remarks that the young arc variegated (livree tragen) ; that this 

 species also inhabits the central chain of the Andes, and prefers the cold 

 region ; that the female is also black, and that no naked spot on the rump of 

 the young animal is observable. 



From the anatomical remarks which Eudes-Deslongchamps has made on 

 the common American Tapir, it appears that the deep broad groove on the 

 external surface of the skull between the nasal and frontal bones, does not, 

 as has been assumed, serve for the attachment of the proboscis, but is 

 occupied by a fibre-cartilaginous sac, the base of which is twisted in a 

 half-spiral. It communicates with the cavity of nostrils by an elongated 

 opening. It is the ak 1 nasi, altered in position. The muscles of the
