44 ON BIRDS FROM MOUNT TENGGER. 
NOTE IX. 
ON A SMALL COLLECTION OF BIRDS FROM MOUNT 
TENGGER, EAST JAVA 
BY 
Dr. E. D. VAN OORT. 
In January 1911 Mr. E. Jacobson spent some weeks at 
Nongkodjadjar on Mount Tengger, Hast Java, at an eleva- 
tion of about 1200 m. above sea-level. Here he brought 
together a small collection of birdskins, 24 specimens be- 
longing to 18 species, which he kindly presented to our 
Museum. The collection contains one form, a Crocopsis, 
that seems to be an undescribed subspecies. 
In the following lines an enumeration of the species is 
to be found; where necessary, I have referred to my list of 
the birds, collected by Mr. Jacobson is West Java, published 
in this periodical, vol. XXXII, 1910, pp. 105—166. 
The native names are given in the javanese language 
of the lowlands.
