HOLLAND AND PETERSON: OSTEOLOGY OF THE CHALICOTHEROIDEA. 211 
Genus CHALICOTHERIUM Kaup. 
Kaup, “Description d’Ossements Fossiles de Mammiféres Inconnus Jusqu’é 
Présent, qui se trouvent au Muséum Grand-Ducal de Darmstadt,” etc., 
Second Cahier, pp. 4-8 (1833). 
Type: C. goldfussi Kaup, I. c. 
Type Specimens: One upper and one lower molar described and figured by Kaup, 
also a canine, which is now known not to have belonged to the same animal, 
and is totally unlike what we know of that tooth in this and other Chalico- 
therine genera. Subsequently other specimens were found in the same general 
locality, and these are preserved in the Museum at Darmstadt, and being 
referable without doubt to the same species, and dating from the time of 
Kaup, are regarded as neo-typical. 
Location of Types: Grand-Ducal Museum in Darmstadt. (Casts in the Carnegie 
Museum. ) 
Geological Horizon: Eppelsheim, Germany (Upper Miocene). 
? ? 
Generic Cuaracters: Dentition 15, C5, Ps, Ms; upper molars broader 
than long, the molar series being relatively shorter than in Macrotherium, 
and much shorter than in Moropus or Nestoritherium; crowns brachyodont, the 
outer walls bent inwardly as in the preceding genus, and the vertical crests 
of the ectoloph gently rounded; proximal phalanx short, relatively shorter 
in the shaft than in Macrotherium, depressed, broad; ungual high and laterally 
compressed as in Macrotherium. 
Genus CIRCOTHERIUM® gen. nov.’ 
Type: Chalicotherium (Anoplotherium) sivalense (Falconer & Cautley), Transac- 
tions of the Geological Society of London, Vol. V, p. 502 (1837); Fauna Antiqua 
Sivalensis, VIII, Pl. 80 (1847); Paleontological Memoirs and Notes of the 
late Hugh Falconer. etc., by Charles Murchison, Vol. I, p. 208, Pl. 17 (1868). 
’ The canine figured by Kaup, as has already been pointed out, does not belong to the Chalicotheroidea. 
6 kipxos = a falcon, in playful reference to the name of Dr. Falconer; dnpicov = a wild beast. 
7 The generic identification of Nestoritheriwum Kaup, founded upon the specimen from Pikermi, with 
Chalicotherium siwalense (Falconer and Cautley), made by Falconer on the occasion of his visit to Munich in 
1861, and apparently accepted by Lydekker in his Catalogue, is not, in the light of our studies, one which can 
stand. Weregret very much to be compelled to add another generic name to those which have been employed 
in designating the Chalicotheres, but as the type of Nestoritherium, as has already been pointed out, is un- 
doubtedly the specimen in Munich (= pentelicuwm (Gaudry et Lartet)), the Indian species, which is characterized 
by a brachycephalic skull and by having a canine in the lower jaw which is not found in Nestoritherium, so far 
as existing material shows, must be separated generically, as we have done,
