ON ARACHNOTHERA LONGIROSTRA (LATHAM) 
BY 
Dr. E. D. VAN OORT. 
The typical habitat of Arachnothera longirostra (Latham) — 
Ind. Orn. I, 1790, p. 299, Certhia longirostra — is Ben- 
gal, This form is spread over an extensive area, but spe- 
cimens of some of the Malay islands show differences with 
those of the continent of Asia. How far away from Ben- 
gal the typical form is found, I am not able to say with 
full certainty, as the material 1 have at my disposal from 
the continent and also from Sumatra is very poor, but it 
seems to me that examples from the continent, from the 
_ Malay Peninsula, from the Riouw-Lingga Archipelago, from 
Sumatra, Banka and Billiton belong to one and the same 
form. As said, my material from these parts however is very 
poor. In the Leyden Museum there are 1 specimen from 
Tenasserim, 5 specimens from Sumatra, 2 from Billiton, 
5 from Banka, 8 from Nias, 9 from Java, 16 from Borneo, 
1 from Celebes and 2 from the Philippines. Through the 
kindness of Dr. Hartert I received for examination from 
the Rothschild Museum in Tring 10 specimens from the 
continent, 2 from Lingga, 10 from the Natoena Islands, 
2 from Serasan, 2 from the Mentawei Islands and 1 from 
Borneo, The results of the examination of this material 
are the following. 
The specimens from Sumatra, Banka, Billiton, Lingga, 
from Malakka and from other parts of the continent be- 
long very likely to the typical Arachnothera longirostra 
(Latham); the bill measures from 34 mm. (QQ) to 41 mm.
