Three specimens of porcupine from southwestern Borneo may be 

 referred to Acanthion longicaudum. It is not probable that the Bor- 

 nean Acanthion is the same as the Sumatran one, but there is no 

 satisfactory material from Sumatra in the U. S. National Museum to 

 permit of comparisons, and no name so far as I know has been pro- 

 posed for a Bornean Acanthion. In 1907 I applied Giinther's name 

 crassisjrinis 3 to the Bornean Acanthion. Mr. Gerrit S. Miller, jr., 

 has subsequently examined the type of that species in comparison 

 with specimens of my Thecurus sumatrse 4 and reports that the two 

 are congeneric, but distinct species.
