The Malay Bear or B ruwang is of comparatively small build, 
and has still disproportionally shorter, at the same time still more 
muscalar limbs than the other Bears. He uses his out of proportion 
enormous claws as dexterously as powerfully. Considering the size 
of his body he is by far the strongest of his race; he is also the 
best climber and the swiftest runner. As regards motor mechanism 
he may be called the most perfect of the Bears. 
His very marked macrocephaly results from the very considerable 
size of the encephalon, which also manifests itself in the brain- 
weight and cranial capacity. 
Weser') determined the body weight of a male Béruwang of 
114 em. body length (from nose to rump), which had died in the 
Amsterdam Zoological gardens, and was probably much too light, 
at 20 kilograms, the brain weight at 325 grams. HRDLICKA®) found 
for the brain weight of a female specimen from the Washington 
Zoological Park, weighing 45.02 kilograms, 385.5 grams. According 
to records by BrANForRD®) the weight of a female bear of Borneo 
was 60 Ibs. or 27.215 kilograms, with 36 inches or 91.5 em. body 
length (from nose to rump). The male body length is averagely 4 
feet or 122 cm., and probably never becomes greater than 4'/, feet 
or. 13%, cnr 
l have been able to measure the capacity of five adult skulls 
from the Museum of Natural History at Leiden, placed kindly at 
my disposal for this purpose by the director Prof. E. D. van Oort: 
N°. 1. (“b. Sumatra-Reinwardt’). Male skull. Basal (basion-inion) 
length (Flower) 214 mm. Greatest breadth, across the zygomatic 
arches, 190 mm. Middle-aged from the degree of wear of the teeth. 
(BLANFORD measured at a “very old and large skull” 8.5 inches 
basal length or 216 mm., and 8.3 inches or 211 mm. breadth]. 
Capacity (measured with mustard seed)*) 373 em’. 
N°. 2. (“f. Borneo). Male skull. Middle age. Basal length 214 mm. 
Greatest breadth 188 mm. Capacity 355 em’. 
N°. 3. (“e. Borneo. S. Müller 1827”). Female skull. Middle age, 
Basal length +187 mm. Greatest breadth, across the zygomata, 
163 mm. Capacity 325 em’.
