The “ pick of the new species of Ruwenzori is, we should 
say, the large Sun-bird Nectarinia dartmouthi, named after 
the Earl of Dartmouth, who was a most liberal supporter of 
the Expedition. This beautiful creature is found only on 
Ruwenzori, where it frequents the Lobelia- and Groundsel- 
Zone from an elevation of 12,500 up to 14,500 feet. In 
the early morning, when the sun shines, this tract seems 
alive with the birds, which appear to feed entirely upon 
the Lobelia blossoms. It seems to be rather remarkable 
that no truly arctic form of bird-life was met with on 
Ruwenzori. 
Mr. Ogilvie-Grant not only invented the idea of the 
Ruwenzori Expedition, but procured the necessary means 
among his friends to execute it and selected the best 
persons to carry it out. He has now further increased the 
gratitude due to him from naturalists by this excellent 
memoir on its results as regards the Class of Birds. 
63. Pycraft on the Anatomy of Bradypterus. 
[On some Points in the Anatomy of Bradypterus cinnamomeus. By 
W. P. Pycraft, F.Z.S., M.B.O.CJ. Trans. Zool. Soc. xix. Part 4, p. 454 
(1910). 
We are always glad to receive a contribution (however 
small) from Mr. Pycraft’s large stock of knowledge of the 
structure of birds, but are rather at a loss to understand why 
he should have been set to work on this Bradypterus , which 
offers few, if any, very striking peculiarities, and of which 
there is only one specimen available. 
The pterylosis of this bird is figured and some of the 
muscles of the wing and leg are described, but “ without 
material for comparison/'’ we are told, it is not possible to 
say anything definite as to the exact position of Bradypterus. 
It is, however, we suppose, a true Passerine form with feeble 
powers of flight, as shown by its short wing and the shallow 
keel of the sternum.
