218 NOTES. 
Notes from Sarawak Museum. 
On a Fossil Tooth found at Bau, Upper Sarawak. 
A molar tooth of the Indian elephant (Hlephas indicus) was 
recently found ina small cave at Bau, Upper Sarawak, by a 
Chinaman, whilst washing for gold, and was handed over to me 
by Mr. Pawle of the Borneo Company, whose kindness in so do- 
ing, I beg to acknowledge here. The tooth is an undoubted 
fossil, as shown by a longitudinal section subsequently made, 
but since it was lying in a crevice in the limestone, not actually 
imbedded in rock, it is impossible to state with any degree of 
accuracy the exact horizon of the specimen. The limestone in 
this part of Sarawak is undoubtedly of comparatively recent ori- 
gin, aS Shown by fossils collected by me; such characteristic 
shells as Cerithium and Limopsis being here abundant ; the form- 
ation is honeycombed with caves, many of which were carefully 
explored in 1878-9 by the late Mr. A. H. Everett. His results 
were embodied ina report to the Royal Society (Proc. Roy. 
Soc. No. 203, 1880) and he there states it as his opinion, that it 
is unlikely that deposits of any great antiquity or interest will 
be found in this area; subsequent observations have Justified 
and will, ] think, continue to justify these words; the fossil 
tooth, the subject of this note, is interesting only because it 
proves conclusively that which formerly was argued inductive- 
ly, ez :— that the Indian elephant was once an indigenous in- 
habitant of Borneo. In Mr. C. Hose’s ** Mammals of Borneo,” 
Elephas indicus is included as an indigenous species; but there 
is little doubt that the few individuals now existing in North 
Borneo have sprung from some pairs which were introduced 
some years ago, certainly within the memory of living man. 
These pairs were presented by a Sultan of Pahang to the Sultan 
of Brunei or Sulu (for on this point accounts differ), and after 
they had been kept in semi-captivity for a year or two, were 
turned loose into the jungle. Considering the low rate of breed- 
ing of elephants it is not surprising that their present distribu- 
tion in the island of Borneo is so extremely local. It is also 
worthy of note that the Kyans at the head of the Rejang and 
Baram rivers, areasin which tke rhinoceros and wild buffalo
