" Landak" of the Malays of the Peninsula. 

 Hab. — Pinang, Malayan Peninsula. 



Java, Sumatra, Borneo. 

 The nose, lips, forehead, and back of the feet, are covered with 

 greyish-brown hairs. The body and limbs at the root of the spine, are 

 covered with dense soft silky hairs, grey on the upper parts, and silvery 

 on the abdomen. Single longer flexible spines, white with a dark 

 central band, are scattered over the back. The anterior part of the tail 

 is, like the back, covered with flat- grooved spines, white at the root, 

 then slightly iridescent brown, and frequently with white apex. The 

 centre part of the tail is scaly, with very short spines between the scales. 

 The posterior part is white ; with white or silvery, flexible, and in length 

 gradually increasing, spines, which Buffon has aptly compared to nar- 

 row slips of irregularly cut parchment. The pubes are of a deep rust 

 colour. 



This species is very numerous in the Malayan valleys and hills. In 

 fretful habits, and in its food, it resembles the preceding porcupine, 

 like which, it is carried to the market at Pinang and Malacca, where as 

 many as twenty to thirty may frequently be seen. In a male, measur- 

 ing from the apex of the nose to the root of the tail one foot ten inches, 

 the tail ten inches ; the intestinal canal was of the following dimensions :

The stomach is of a general outline, resembling that of H. longicauda, 

 but it differs in having an external deep vertical sulcus, dividing the 

 stomach into a pyloric and a cardiac portion, which latter presents 6 to 7 

 deep oblique sulci. The membranes of the stomach are thick and mus- 

 cular. Internally the cardiac portion is transversally divided by six or seven 

 ridges, corresponding to the external sulci, intersected by numerous con- 

 centric rugae. The pyloric portion, separated from the cardiac by the 

 rugae produced by the external vertical sulcus, is much smoother, and 

 has but few rugae.
