S26 Dr. Horsfield on the Helarctos Euryspilus, 



gradually rise to the crown of the head, oa which they are densely 

 disposed, nearly erect, and very soft to the touch. 



The Helarctos from Borneo has the pure, saturated jet-black 

 iiHt which is observed in the Malayan Bear, on the body, head, 

 and extremities. The muzzle including the region of the eyeS, 

 tias i yellowish brown colour ; the mark on the anterior part of 

 the neck is more vivid and nearly orange ; this diflfers in form from 

 that of the Malayan Bear and constitutes the chief distinction of 

 the Bornean species. It is a large, broad mark of an irregular 

 <Juadrangular form, occupying a considerable portion of the neck, 

 anteriorly. Underneath or posteriorly it is very slightly emargi- 

 uate, but above it has a deep notch, gradually contracted at 

 the base, with regularly defined sides, from which the points 

 are very gradually diverging. The contour of the mark is very 

 slightly curved laterally. A transverse band of a gray co- 

 lour is formed on the feet by tufts of long bristly hairs arising 

 ht the insertion of the claws ; its value as a specific distinction 

 remains to be determined by future comparisons. 



The Helarctos from Borneo, now exhibited in the Tower, mea- 

 sures along the back from the muzzle to the tall three feet nitie 

 inches. In an erect posture it frequently raises itself to four fefet. 

 In its usual attitude the heiglit at the rump is eighteen inched. 

 The length of tlie anterior extremities is one foot seven, and of the 

 posterior one foot five inches. The circumference of the head is 

 one foot ten, and of the body two feet five inches. The measiire 

 across the head from ear to ear is about nine, and the leiigth df 

 the middle toe and claw of the fore foot four and a half inches. 

 Judging from these dimensions, our animal is somewhat smaller 

 than the Malayan Rear ; the largest prepared specimen of this 

 which I have examined measures along the back four feet «x 

 inches. 



The Helarctos eurijspilus which is now described, was brought 

 to this country above two years ago, and may therefoi'e be sup- 

 posed to have acquired its full size. The keeper has not per- 

 ceived any increase in its diniensions for a considerable time. Otit 

 animal forms at present one of the most attractive and interestiiig 

 spectacles among the animals cofifined in the Royal MenageVie.
