Europe. In the basin of the Rhine they are found in the Loess and in the 

 bone-caves. The remains of the Rhinoceros Merkii have been collected near 

 Mauer, in the valley of the Neckar, in a deposit of sand and gravel inferior to 

 the Loess ; and at Mosbach, near Wiesbaden, it seems to occur in deposits 

 lower than those which contain R. tichorhinus in the neighbouring valley of 

 the Lahn. According to Hermann de Meyer, R. Merkii therefore made its 

 appearance before R. tichorhinus ; it occupied the lower part of the Quaternary, 

 and the latter species the upper portion, although it is not proved that, in 

 some places, the two species did not live together. According to Lartet 

 (Ann. des Sci. Nat. 1867, vol. vii. p. 27), R. Merkii, De Meyer, is not the 

 species described by Jaeger and Kaup, but the same as R. etruscus, Falc. ; 

 Prof. Heer therefore gives it the latter name.
