inner cusp to pm . 4, corresponding to the hinder of the two inner 

 cusps in the homologous tooth of U. spelceus. In one recent cranium 

 (B. M. No. 1137 &), however, this cusp is absent ; and it is also 

 wanting in some of the specimens noticed below. 



Hob. North America (Recent), and Europe (Pleistocene). 

 1 (0. C.). Cranium and mandible, wanting the upper incisors, the 

 (Fig.) earlier premolars, and the right zygomatic arch ; from a 

 cavern in Muggendorf, Franconia, Bavaria. This fine 

 specimen is the type of the so-called Ursus fossilis, and is 

 figured and described under that name by Goldfuss in 

 the Nova Acta Ac. Ca3s. Leop.-Car. vol. x. pt. 2, p. 259, 

 pi. xx. c. It is also figured, under the name of U. prisons, 

 by Cuvier in the ' Ossemens Fossiles,' vol. iv. pi. clxxxix. 

 figs. 5, 6 (1823) ; and the right lower dentition is figured 

 by Owen in the ' British Fossil Mammals and Birds,' 

 p. 106, fig. 35s, under the same name. The specimen is 

 of relatively small size, and the cheek-teeth are but little 

 worn. S'ommering Collection. Purchased, 1827. 



M. 230. Cranium of a very large male ; from alluvium near Balli- 

 (Fig.) namore, County Leitrim, Ireland. In this specimen all 

 the teeth except the canines and the last true molars have 

 fallen from their sockets. It is described and figured by 

 Leith Adams in the Proc. R. Dublin Soc. new ser. vol. ii. 

 p. 51, pi. iii. (1878). The last molar is unusually narrow 

 behind. EnnisTcillen Collection. Purchased, 1882. 



28906. Cranium, wanting the incisors, some of the cheek-teeth, 

 and part of the left zygomatic arch ; from a bog at 

 Clonbourne, near Parsonstown, King's County, Ireland. 

 This specimen is of medium size, and the molars are very 

 much worn ; it is described by Leith Adams in the Proc. 

 R. Dublin Soc. new ser. vol. ii. pp. 53-4. 



Transferred from the Antiquarian Department, 1854. 



38153. Cast of the cranium, wanting all the teeth; from a bog 

 between Moyvore and Ballymahon, County Longford, 

 Ireland. The original of this specimen is in the Leeds 

 Museum, and seems to be the original of Ursus plani- 

 frons, Denny : it is described by Leith Adams in the Proc. 

 R. Dublin Soc. new ser. vol. ii. pp. 52-3. 



By exchange toith the Royal Dublin Society.
