SIWALXK SELENODONT SUINA, ETC.

Owing to tlie imperfect condition of the specimens, further comparisons are 
impracticable, hut the differences pointed out confirm the inferences drawn from the 
upper molars as to the former existence of two species of large hyopotamids in the 
Bhugti hills. It is very remarkable that in one small spot (for all the remains of 
these forms were collected by Mr. Blanford in one day), remains of two such highly 
interesting, and previously totally unknown forms, should have been obtained, and 
it points to the great promise of these districts as a future field of research. 
Since, however, the Bhugti hills are beyond the British frontier, among unruly 
tribes, it requires special arrangements by Government to enable any European 
visitor to travel through them, and it is hence unlikely that any scientific person will 
again visit them for a long period. The locality whence most of Mr. Blanford’s 
specimens were obtained is known by the name of Gdndri. 
Group B: TETR ACU8PID ATI. 
Upper molars with only four columns. 
Family 2. — MER YCOPO TAMID2E. 
Characters. — This family may be defined as selenodont Suina in which the upper 
molars have only four columns, while the mandible, as far as is known, is furnished 
with a large descending plate, or process, at the angle ; the latter character 
distinguishing it from the Oreodontidce. 
Genus I : MERYCOPOTAMUS, 1 Falconer and Cautley. 
As this and most of the succeeding genera are each represented by only a single 
species, the generic characters are the same as those of the species. 2 
Species. Merycopotamus dissimilis. Falconer and Cautley. 
Synonyms. Hippopotamus dissimilis. F. and C. 
Merycopotamus sivalensis. F. and C. 
History. — In the year 1839, Messrs. Falconer and Cautley 3 described the remains 
of a pig-like animal from the sub-Himalayan Siwaliks, under the name of 
Hippopotamus dissimilis. Subsequently it was found that the teeth differed so 
essentially from those of the hippopotamus that a new genus — Merycopotamus — was 
created for the reception of this form. A fine series of the remains are figured 
under the latter name in the “ Fauna Antiqua Sivalensis,” 4 most of which are now 
in the British Museum. There is also a fine series in the Indian Museum. A notice 
of the osteology of this remarkable form was published by the present writer in the 
1 From tnertix, a ruminant, and potamos a river. 
2 A second species of Merycopotamu t is mentioned by Dr. Falconer, but cannot be identified.
