Distrihutio)). — Java. 



Reiaarloi. — I have seen no specimens of this species. There is a 

 skeleton of an old individual in the National Museum, labeled '"'//j/.s- 

 tr'm javanica; Java." It was purchased from a dealer several years 

 ago, and probably labeled "Java" because it had been identified as 

 Hystrix javanica. The total length of the skull measures 135 mm. 

 It is distinctly smaller than skulls of like age from the Mala}^ 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. 



ACANTHION CRASSISPINIS (Giinther).

Distrihution. — Borneo. 



Diagnostic cliaTacters. — Size small; skull, total length 11<) mm. 

 Spines thick, equal twice the diameter of an incisor, longitudinally 

 grooved on their upper surfaces. 



Eemarl's. — I have seen no specimens of this species, but Gimthej''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 hrachyurxmi or longlcaudum. His measurements show it 

 to be a smaller animal than A. javanicimi. 



In Mamnials of Borneo^^Ylo'&Q, records Hystrix m-wZZt;;'/ Jentink, also 

 from Borneo, saying: "This porcupine is like Hystrix crassispinis., 

 but distinguished from it b}'^ its black belly and somewhat different 

 caudal quills. The skull also differs, but the size of the animals are 

 much the same." In all probability A. crassispinis 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
