66 MR. O. THOMAS ON THE MAMMALS OF [Jan. 19, 
other hand those of North Tenasserim are nearly entirely Burmese, 
although but few of them, again, are the same as the species found 
still further north in Manipur. 
The careful and conscientious manner in which Mr. Davison’s 
collecting and labelling is done is nowhere more conspicuous than in 
the beautiful series obtained by him in Tenasserim, so that the 
number and excellence of the skins, and above all, the careful 
preservation of the dates of capture, have been to me, and I hope 
will be to others, of the greatest possible service in making out the 
problems of distribution, and of local, sexual, and seasonal 
variation. 
The collection contains 86 specimens, referable to 25 species. 
1. Hyzosartes xar, L. 
a, b. Myawadi'. e. Kankaryit, 13/1/77. d-g. Bankasun, 
4-6/77. 
2. SEMNOPITHECUS FEMORALIS, Horsf. 
a. Bankasun, 15/4/77. 
This rare species forms an addition to the fauna of Tenasserim, 
the few localities as yet recorded for it being all either in the south 
of the Malay peninsula or in Sumatra. Mr. Davison’s specimens 
precisely agree with Horsfield’s type preserved in the Natural His- 
tory Museum. 
3. SEMNOPITHECUS OBSCURUS, Reid. 
a, 6. 5000', Mt. Mooleyit, 30/1/77. c. Foot of Mt. Nwa-la- 
boo, Tavoy, 10/4/78. d. Bankasun, 25/5/77. 
Specimen d is a very remarkably coloured individual differing from 
all others that I have seen in having its crest, nape, arms and legs, 
and tail yellow, contrasting markedly with the dark hues of the face, 
body, and feet. It is, however, led up to by a specimen in the 
Museum from Malacca, collected by Dr. Cantor *, which has its 
crest yellow and its limbs and tail lighter than usual. I am therefore 
indisposed at present to look upon the Bankasun ‘specimen as more 
than an individual variety. It must, however, be mentioned that its 
auditory bulle are larger and more projecting, and its teeth smaller than 
is usually the case ; but with only a single specimen, these characters 
are not sufficiently tangible to found a new species upon. 
4. Macacus cynomo.eus, L. 
a. Wimpong, Thatone. 
5. PrroNODON MACULOSsUS, Blanf. 
a. Bankasun (co-type of species. Figured J. A. S. B. xlvii. 
pl. vi. 1878). 
This is the original skin described and figured by Mr. Blanford, 
1 Specimens to which no collector’s name is attached were obtained by Mr. 
Davison.
