Recently published Ornithological Works. 559 



of 24 species. The plates have been drawn by Gronvold 

 and chromo-lithographed by Green. 



The " pick " of the new species of Rnwenzori 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. Py craft on the Anatomy of Bradypterus. 



[On some Points in the Anatomy of Bradypterus cinnamomeus. By 

 W. P. Pycraft, F.Z.S., M.B.O.U. 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.
