Dikfribut Ion. — Java. 
Remark #,—I have Been no specimens of this species. There is a 
skeleton of an old individual in the National Museum, labeled “//>/,?- 
trix javuniea; Java.” It was purchased from a dealer several years 
ago, and probably labeled “ Java w because it had been identified as 
Hysirlx jar am at. The total length of the skull measures 135 mm. 
It is distinctly smaller than skulls of like age from the Malay Penin¬ 
sula, but at the same time much larger than the 118 mm, given by 
Jentink" as the total length of a Javan Acanthion skull.

Diagnostic characters .—Size small; skull, total length 110 mm. 
Spines thick, equal twice the diameter of an incisor, longitudinally 
grooved on their upper surfaces. 
Remarks .-—I have seen no specimens of this species, but Gunther’s 
original description shows that it is a well-marked form. His plate 
would indicate that it is a lighter (browner) colored animal than either 
Acanthion brachyurum or longicaudum. His measurements show it 
to be a smaller animal than . L jamnicum. 
In Mammals oj'Borneo , fr Hose records Ilystrix mulleri Jentink, also 
from Borneo, saying: “This porcupine is like Hystrix erassispinu^ 
but distinguished from it by its black belly and somewhat different 
caudal quills. The skull also differs, but the size of the animals are 
much the same.’ 1 In all probability /I. crcmispinia has a dark belly, 
although there is nothing in the original description to show that the 
belly is light or dark. It is thus impossible to say how Hose’s second 
species of short-tailed porcupines from Borneo differs from Acanthion
