Jentink ') has already shown , that Semnopithecus ferrugineus of 
Schlegel can not be separated from S. melalophus Raffles, as they 
are distinguished exteriorly only by a sUght difference in tinge, and 
that the difference in number of ribs, as believed by Schlegel ^) does 
not exist really. I can confirm this view in every particular and can 
add a new argument against Sohlegel's opinion. Comparing the ske- 
leton of two specimens, both shot at Manindjau and both belonging 
to S. melalophus, after the description of Schlegel, one has 13 ribs 
but only 5 lumbal vertebrae, the other has 12 ribs but 6 lumbal ver- 
tebrae. The number of ribs is therefore not specifically different as 
already stated by Jentink. 
Schlegel believes, that S. ferrugineus hves in the plains and 
mountainous district of Padang and is substituted in the South-East 
of Sumatra by S. melalophus. \ 
Now I have found both together in the same district, I may say 
living together. Therefore also this argument for separating S. mela- 
lophus and ferrugineus can not be sustained.

Gercocebus. ■ 
Cercocebus cynamolgus Schreber. 
Sumatra: Manindjau; skeleton cf (175). 
Flores: Bari; c? (71) and a skull found in the forest. 
Besides these I saw specimens at Reo and Sikka at the North-

In South-Celebes I noticed a specimen in captivity at Pare-Pare and 
my Malay hunters observed a specimen in the forest at Loka near 
Bonthain.
