204 THE BEARDED PIG IN THR MALAY PENINSULA. 
“The specimen is an absolute topo-type of Sus oi and in view 
of certain differences between it and the description and measure- 
ments of the type merits more detailed description. The animal 
is very fully adult but not aged. The naso-frontal suture is still 
visible but the basi-occipital is completely ossified. The teeth 
including the posterior molars in both jaws are somewhat worn 
but not so that the details of the enamel spaces cannot be 
recognized. 
“Viewed in the basal aspect, the rostrum, aie to the 
canines is broader than in similarly aged specimens of S. barbatus. 
The zygomata are more heavily built and more divergent and the 
tusk sheaths more recurved than in the Bornean animal while the 
cranial region is more sharply bent upwards from the level of the 
orbits. T’he mandibular symphysis is longer and this region of 
the jaw heavier than in Sus barbatus of equal size. Mr. Miller 
states that out of the specimens examined by him only two, the 
type and a specimen from Palembang, had the posterior molars in 
a eondition fit for examination. ‘The diagnosis of the race, how- 
ever, depends on the fact that in Sus oi the upper posterior molar 
has ‘its posterior portion much narrowed* the lower tooth lacking 
the terminal heel but with the third transverse ridge reduced to 
a terete heel-like remnant.’ ” 
Further examination of larger series from Borneo and else- 
where now convinces us that real differences between the Bornean 
animal and others from Rhio and Sumatra have not yet been 
demonstrated and that all the alleged characters of skulls from 
the latter localities can be explained by the varying age and innate 
variability of the specimens examined. 
We are therefore of the opinion that there is no justification 
for regarding Sus ot as distinct, even subspecifically, from Sus 
barbatus and we therefore retain this last name to cover the 
Bearded Pig of Borneo, Sumatra, the Rhio Archipelago and 
Pahang. 
The Giant Pig of South East Borneo and that from portions 
of Eastern Sumatra may possibly be a distinct race or even 
species as suggested by Kloss but we have no material on which 
to base an opinion. The former has been named Sus gargantua, 
Miller, and is based on a single not very old skull in the collection 
of the Agricultural High School, Berhn, from an unspecified 
locality in South East Borneo, which is the largest known skull 
of the genus Sus in any collection. The Sumatran form, as yet 
known from native accounts only, has been inadvertently named 
Sus branti by Kloss (antea) though as the name is accompanied by 
a description it will, by the laws of nomenclature, stand.

Sumatran and Rhio Archipelago specimens of Sus barbatus is

erupted but hardly worn) from Sarawak.’’
