188 THE KANGAROOS. 



there is not, therefore, so distinct a tuft ; these hairs 

 are brown, and not black, and the dark hairs are 

 nearly confined to the tip of the tail, whereas in H. 

 penicillatus they extend a considerable distance 

 along the upper surface ; the ears are rather larger 

 and the head is longer ; the lower front incisors are 

 much shorter and stouter, the upper front incisors 

 are much stouter; the distance between the fore part 

 of the anterior incisors, (upper jaw) and the hinder 

 part of the canines is 6^ lines ; the space betweer. 

 the canine and posterior incisor is about 1 line. In 

 H. penicillatus there is not more than half a line 

 between the canine and incisors, and the distance 

 between the anterior of front incisor and hinder part 

 of canine, is a trifle more than 5 lines; from fore part 

 of front incisor, upper jaw, to the first molar, 10 

 lines. The specimen apparently is a male, and is 

 contained in the Museum of the Zoological Society.
