274 TJNGULATA. 



Monte Bamboli (Tuscany), Italy. The specimen shows all 

 the cheek-teeth except pmTT; the length of the space 

 occupied by the three premolars is 0,042, and that by the 

 true molars 0,065. The jaw is apparently more slender 

 than the mandible of S. palceochoerus figured by Kaup in 

 the Oss. Foss. d. Darmstadt, pt. ii. pi. ix. fig. I, and the 

 premolars are relatively smaller. Purchased, 1863. 



37345. Cast of part of the right ramus of the mandible of a young 

 individual, showing the last three milk-molars and m . i. 

 The original is from the Middle Miocene of Monte Bamboli. 

 The length of Z^Tl is 0,021 . Purchased, 1863. 



FAMILY and GENUS non det. 

 Hob. India. 



M. 2095. The left half of a cranium, with the crowns of the teeth 

 (Fiy.) hammered off; from the Pliocene of the Siwalik Hills, 

 India. This specimen is figured by Falconer and Cautley 

 in the ' Fauna Antiqua Sivalensis,' pi. Ixvii. fig. 2, under 

 the name of Merycopotamus dissimilis, but the base of 

 the molars indicates teeth of a much simpler type. 

 The general contour of the cranium is suilline, but 

 the narrow premaxilla and the form of the maxilla in 

 advance of the orbit apparently differentiates it from Sus, 

 to which the present writer at first referred it 1 . In the 

 absence of the crowns of the teeth it appears impossible to 

 determine the present affinities of the specimen.

M. 2096. Symphysial extremity of the mandible of an apparently 

 suilline animal, perhaps specifically identical with the last 

 specimen ; from the Pliocene of the Siwalik Hills. This 

 specimen shows the alveoli of the incisors and canines, 

 and is remarkable for the extremely narrow interalveolar 

 channel, which forms a deep spout-like groove.

 canines and last molars have a tendency to disappear in old animals.
