FASCICULI MALAYENSES 
The measurements are as follows : — Greatest length, 140 mm. ; Hen- 
selion to edge of occipital foramen, 113 mm. ; Zygomatic breadth, 72 mm. ; 
Length of nasals, 61 mm. ; Greatest length of frontals, 51 mm. ; Breadth of 
nasals at posterior edge of praemaxilla, 30*5 mm. ; Ditto at tip, 23 mm. 
It will be noticed that in these specimens the nasals are about 10 mm. 
longer than the greatest length of the frontals, whereas in H. yunnanensis^ which 
was brought back by the ‘ Skeat ’ Expedition two years ago, the nasals are 
4 mm. shorter than the frontals. I have, however, compared these skulls 
with that previously identified as H. yunnanensis^ and consider that they all 
belong to the same species. 
‘ Porcupines, presumably of this species, must have been exceedingly 
abundant round Biserat, especially in the caves, the floors of which were covered 
with innumerable tracks, but no trap that we could obtain proved effectual. 
The series in the collection were obtained for us by natives, and were dug 
from their holes in deep jungle. The immature specimen of which only the 
skull was preserved, was found in the same hole along with one of the females 
and an adult male, which escaped, and the remaining pair were captured 
together. Both the females contained a single fairly advanced embryo, so 
that it is evident that the young ones remain with their parents until the young 
of the succeeding year are born. 
A wound from a porcupine’s quill is considered by the Malays as very 
dangerous, and we were solemnly informed that if the quill penetrated as far 
as the first dark ring, the injury would inevitably prove fatal. 
Locally this species is known as landak^ the brush-tailed porcupine being 
called landek'
