very constant, and no approach is shown to the tawny of Macacus 
'''' cynomolgiisr 
This monkey was supposed by Zelebor to be the same as Macacus 
carhonarins^ an animal from Sumatra, described by F. Cuvier in the 
Histoire Naturelle des Mammiferes/ That such is not the case is 
clearly proved by Cuvier's description and figure, both of which refer 
to an individual of the tawny ^ cynomolgus'' type. 
Macacus umhrosus has long been known as an inhabitant of the 
Nicobar Islands. It was recorded by Blyth as long ago as 1846. 
Blanford suggested that it might have been introduced,' but the rea- 
sons for this supposition are not given.

SUMMARY. 
The mammal fauna of the Andaman and Nicobar islands is now 
known to consist of 35 positively identified species and 4 others whose 
status is still in doubt.'' Their distribution is shown in the accompany- 
ing tabular summary, in which the letter "A" indicates material obtained 
by Dr. Al)bott, the letter ""R" a previous record. 
On comparing this fauna with that of other islands in the Malay 
region,* two remarkable features are at once noticeable, the prevalence 
of bats and rats and the absence of practically all of the characteristic

^Two animals of known recent introduction are not included. These are the 
domestic goat on Barren Island, Andamans, and the l)uffalo on Kamorta Island, 
Nicobars. The goats were placed on Barren Island son.e years ago by the Port Blair 
authorities and at the time of Dr. Abbotts' visit had increased to several hundred. 
The buffalo on Kamorta are descendants of individuals left by the Danes when they 
abandoned their settlement. They are few in numbers, and Dr. Abbott and Mr. 
Kloss saw only their tracks. A pair of axis deer were placed in a favorable locality 
on one of the Nicobar Islands by Captain Lewis in 1846 (see Blyth, Journ. Asiat. 
Soc. Bengal, XV, p. 368) , but it is unlikely that the species became established.
