54 PYGCHTHRIX 
Desmarest’s type of S. albo-cimereus is not in the Museum, and to- 
day it is impossible to identify his species. 
Flower, (1. c.) says “Cantor found this species most common in 
Penang and Singapore, and that it also occurs on the Peninsula.” It 
is doubtful, however, he adds, “whether it does occur at Singapore at 
the present time. In April, 1895,” he continues, “I found this species 
very common in Kedah, living in the highest trees along the banks 
of the Kedah River and the tributaries, either solitary or in parties of 
about half a dozen; they were very active and wild. In the Botanical 
Gardens, Penang, I have seen this species playing in the trees. On 
Penang Hill I have occasionally seen Lutongs which appeared to belong 
to this species; they are very shy, and it is difficult to see much of 
them before they disappear among the jungle trees. In the Museum 
at Taiping there are specimens from the Larut Hills, Perak. In April 
1898 at about 3,500 feet elevation in the Larut Hills, I came on a 
party of from 10 to 20 Semnopitheci of this, or a closely allied species.”
