196 ON ARACHNOTHERA LONGIROSTRA (LATHAM). 
Borneo; they have a longer bill, 39 mm. (QQ) to 45 mm. 
(oo), and also a longer wing, 63 (QQ) to 75 mm. (Sf). 
This form is to be called: Arachnothera longirostra prillwitzi 
Hartert (Nov. Zool. VIII, 1901, p. 51). 
The specimen, which should have been collected by 
Dr. Forsten in the north of Celebes, is a pale-breasted, 
long-billed (41 mm.) and long-winged (71 mm.) example, 
that seems to me to be a wrongly labelled javan speci- 
men, that has been prepared moreover from alcohol. 
In the two birds, male and female, from the Philip- 
pines (Mindanao and Samar) the yellow of the under parts 
is bright golden yellow and this colour does not extend 
on the breast like in the other forms; they are short-billed 
(31 and 32 mm.) examples with a length of wing of 62 and 
63 mm. They are to be called: Arachnothera longirostra 
flammifera Tweeddale (Proc. Zool. Soc. London, 1878, p. 343). 
I have not seen specimens of the Palawan form Arach- 
nothera dilutior Sharpe (Nature, 1876, p. 298), but it seems 
to me to be also a subspecies of Arachnothera longirostra.
