CONDYLAETHEA. 443 



face is inclined at an angle of 45° outwards and upwards, and 15° back- 

 wards and upwards. The neural spine is quite narrow anteroposteriorlj 

 and rises at an angle of 45°, overhanging the third vertebra. Its anterior 

 edge is acute to the anterior extremity of the arch, and the posterior face is 

 rounded, with a narrow median keel. 



The third to the sixth cervicals inclusive are preserved engaged in the 

 matrix. Their centra "are rather smaller than those of the Tapirus terres- 

 tris, and are not relatively so robust. Their articular faces have about the 

 same degree of obliquity as in that species, and they have a pentagonal 

 outline deeper than wide. The middle line below is a prominent keel, 

 which expands posteriorly into a triangular hyj^apophysial table, which is 

 truncate posteiiorly. This table is smaller on the fourth vertebra than on 

 the third, but on the fifth it is larger than on the third. On the sixth it is 

 about as large as that on the third, but is less distinct in its outlines, while 

 on the seventh its median line is prominent, and the lateral boundaries al- 

 most obsolete. On the third and fifth centra its lateral borders are espec- 

 ially prominent. The sides of all the centra are concave. The paradia- 

 pophyses are narrow in vertical diameter; that of the third is acuminate 

 posteriorly, the apex extending to the line of the posterior margin of the 

 middle line below. Its inferior edge is only convex. On the fifth this 

 convexity becomes an angle, and the diapophysis begins to project. On 

 the sixth the parapophysial free border is prominent downwards and for- 

 wards as well as backwards, and the diapophysis is quite prominent. On 

 the seventh the diapophysis only remains. The floor of the neural canal 

 is strongly ribbed on the median line. The zygapophyses of one side 

 are connected by a prominent ridge, and the general surface of the neural 

 arch above is flatter than in Tapirus terrestris ; the lateral concavities are 

 more evident on the sixth than on the third vertebra, and the roof is more 

 oblique on each side. Neural spines small. Zygapophysial facets all 

 rather oblique, more so on the seventh than the third vertebra.
