318 ZOOLOGICAL EESTJLTS OF THE EUWENZOEI EXPEDITIOK. 



journey wherever the tree Erythrina tomentosa grows. We met with it on Ruwenzori 

 up to a,n elevation of 7000 ft., but it was not found in the dry acacia-country around 

 the south end of the range, where this tree is very scarce. All the Sun-birds, but more 

 especially those with long bills, which enable them to probe the deep cup of the 

 flower oi E. tomentosa^ are gi'eatly attracted by its clusters of scarlet blossom. N. kili- 

 tnens'is appears to feed on it almost exclusively, and, so far as our experience went, 

 the species is not found where this tree does not occur. — li. B. W.'\

The male of this splendid alpine species is most nearly allied to that of N. salvadorii 

 Shelley, having the same rather short and but slightly curved bill, but is easily distin- 

 guished by having the upperparts of a rather darker green, shading into dark greenish- 

 blue on the rump. The upper tail-coverts, margins of the tail-feathers, belly, sides, and 

 flanks are of the same greenish-blue tint. Iris dark hazel ; bill and feet black. 

 Total length about 10"4 inches; culmen I'l; wing 3"2 ; middle tail-feathers 6'5, 

 lateral tail-feathers 2-3; tarsus 0'8. 



The female is very similar to that of N. jolinstoni Shelley, but is easily distinguished 

 by the shorter and straighter bill. 



The occurrence of this remarkably handsome Sun-bird dwelling on the highest 

 parts of the range, close to the limit of vegetation, was perhaps the most important 

 discovery made by the Expedition. It has been named in honour of the Earl of 

 Dartmouth, who was one of the principal subscribers to the Ruwenzori Expedition. 

 His son, Mr. Gerald Legge, was one of the most successful collectors who took part in 

 this memorable exploration. 



[This beautiful Sun-bird was found only on Ruwenzori, where it frequented the 

 lobelia- and groundsel-zone from an elevation of 12,500 ft. up to 14,500 ft. In the early 

 morning, when the sun generally shines upon the higher parts of the range for a few 

 hours before the cloud-bank has accumulated, these regions seem alive with the males
