304 Mr. 0. Thomas on new 



it sliares the peculiar and liitherto unique character of the 

 hairy band passing across the sole and dividing from eacli 

 other the smooth posterior part and the distal part at the base 

 ot" the toes, where the tubercles are situated. From that 

 species, which was discovered at Wa lehii by Emin Pasha, it 

 is at once distinguishable by its much smaller size. 



Named in honour of Col. Sir Juhn Harrington, British 

 Resident in Abyssinia, without whose active assistance 

 Mr. Zaphiro would hardly have b^en able to carry out his 

 successful collecting-trip. 



Arvicanthis rex, sp. n. 



A very large species without dorsal strlpp. 



Size larger than in any other species. General colour of 

 fore-back between hair-brown and smoke-grey, resulting 

 from a coarse mixture of blackish brown and creamy white ; 

 posteriorly the light colour becomes more and more buffy, so 

 that round the base of the tail and on the lower leg it 

 approaches tawny ochraceous. Sides lined cream-butf. 

 Under surface and inner side of limbs white. Forearms 

 dull buflfy ; hands pale brown; upper side of feet whitish 

 laterally, pale tawny along the middle line. Tail blackish 

 above, dull white on sides and below. 



Dimensions of the type (measured in the flesh) :^ 



Head and body 212 mm. ; tail 175 ; hind foot 3G ; ear 22.

Tupe. Adult male. Original number 101. Collected 

 30th May, 1905. 



This is a remarkably fine species, very different from 

 anything hitherto described. Its colour has almost a sugges- 

 tion of silvery blue-grey in it not easy to describe, but very 

 characteristic, while at the same time its unusual size and the 

 entire absence of any trace of a darker dorsal band will distin- 

 guish it from the other members of the group. Unfortunately 

 the skull is missing, but the species is so distinct as to be 

 readily recognizable by its external characters. 



Lophui'omys Zaphiri, sp. n. 



General colour above greyish, without the warmer tones 

 of the other forms, most nearly matching "hair-brown'' of 

 Kidgway ; very finely speckled with buffy. The bases of 

 the hairs deep rufous. Under surface fawn, more or less 

 suffused witli butfy. Upper surface of hands and feet dull 

 whitish. Tail short, strongly tapering, well haired, nnirkedly 

 bicolor, Ulaek above, whitish below, sharply defined laterally.
