Mr. Charles Chubb on the 
This bird was first recorded from Paraguay by Mr. Bertoni, 
who described it as new to science under the name of Hadro - 
stomus borellianus. The above-mentioned examples, however, 
agree perfectly with other specimens of Pachyrhamphus 
castaneus in the National Collection from various localities. 
I agree, therefore, with Dr. Ihering in placing Mr. Bertoni’s 
name as a synonym of the present species. 
[This species is undoubtedly resident though rare, and can 
at times be met with in the vicinity of the water-courses in 
the large forests.— W. F.] 
Pachyrhamphus castaneus intermedius. 
Pachyrhamphus intermedius Berlepsch, Orn. Centralbl, 
1879, p. 63 ; id. J. f. O. 1879, p. 208. 
The two specimens recorded from Sarayaeu, Ecuador, 
collected by Buckley, are distinguished from P. castaneus 
by the much darker chestnut of the head and back and the 
brighter cinnamon-rufous of the under surface. Total length 
52 inches, culmen 0 6, wing 3*35, tail 2T, tarsus 075. 
Mr. C. E. Hellmayr suggests that these may belong to the 
form described as P. intermedius by Count von Berlepsch 
from Venezuela, to which I agree.
