516 ZOOLOGICAL EESULTS OE THE ErWENZOEI EXPEDITION. 



79. Aevicanthis abyssinicus Eiipp. 



d . 83, 84. ? . 59, 662. Miibuku Valley, E. Euwenzori. 6900 ft. 



c? . 139, 299. ? . 138, 675. Mokia, S.E. Ruwenzori. 3400 ft. 



[Plentiful on Ruwenzori Tip to the lower edge of the forest-zone at 6500 ft., and 

 occasionally seen among the dry acacia-country on the plains around the south end of 

 the range. This species is quite diurnal, and may be seen in the bright sunlight 

 feeding upon the millet put out to dry in front of the native huts. — R. B, W.] 



Family Octodontid^. 



80. Thrtonomts harrisoni Thos. & Wr. 



J . 310. Fort Beni, Semiliki Valley. 3000 ft. 



This species was based on a specimen obtained by Col. Harrison from the Lado 

 District ; another was obtained by the Alexander-Gosling Expedition on the Welle 

 River. 



T. swinderianus occupies, practically unchanged, the whole of the Ethiopian area ; 

 while, so far as we yet know, the group made up of T. grefforianus, T. sclateri, and the 

 present species is limited to a comparatively small area north and south of the 

 Equator (between 25° and 35° E. long.). 



[This animal was not obtained on RuAvenzori, and the natives said it did not exist 

 there, although it was found on the plains below. A single specimen Avas found 

 at Fort Beni, in the Semliki Valley, and it is probable that it also occurs on the 

 north-west slopes of Ruwenzori which join with the Congo Forest. — R. B. W.] 



Family Pkocaviid^. 



81. Procayia ruwekzoeii Neum. 



6 . 71, 256, 624, 628; 73, 267, 268, 269. $ . 68, 260, 261, 648, 649; 270, 271, 

 650. Mubuku Valley, E. Ruwenzori, 10,000 ft. 



The Ruwenzori Dassie was first obtained by Sir H. H. Johnston, from whose 

 specimens Prof. Neumann described the species. 



[Only one species of Hyrax was obtained on Ruwenzori; it was found from 10,000 

 up to 14,200 ft., but is scarce above 12,500 ft. It was most numerous from 10,000 

 to 12,000 ft., frequenting the cliffs and caves among the tree-heath zone. 



The noises these animals make at night are most remarkable : there are two 

 distinct sounds — one a shrill hissing squeal very like the note of a Barn-Owl, but 

 louder ; the other a much lower-toned chattering or rattling sound, not unlike that 

 made by a large frog, but with a hissing sound in it. The native hunters say that the 

 male makes one sound and the female the other. They do not commence these noises 

 immediately it is dark, as might be expected, but some hours later. The cliffs around
