466 Mr. 0. Thomas on new Peruvian Species of 



broader on all parts of the allied species. This difference is 

 most noticeable along the back, where, instead of dark stripes 

 about H inch wide alternating with white ones of half an 

 inch, both light and dark are equally about 1 inch wide. 

 Similarly on the face all the fine light stripes are broader 

 than the dark ones, which latter are, as usual, reddish instead 

 of black. On the ears again the white is increased at the 

 expense of the black. The transverse dorsal markings on 

 the whole are rather more uniform and less irregular than in 

 E. zehra, and they are throughout (except in two cases) 

 divided from each other by a well-definecl narrow median 

 black line which runs from the withers right through on to 

 the tail. The gridiron-pattern of the loins is essentially 

 similar to that of £". zehra, but owing to the alteration in the 

 proportions of the colours would rather be called black 

 markings on a buff ground instead of white ones on a black 

 ground. Upper light rump-stripe nearly twice the breadth of 

 that of E. zebra. 



Length of the tanned skin, from tip of nose to base of tail, 

 8 feet 4 inches. 



Uab. ]\Iossamedes, Southern Angola. Type from Provi- 

 dencia, near the River JMoninho, about 70 kilometres N.E. of 

 Mossamedes. Altitude 300 m. 



Type. Male. B.M. no. 0. 9. 12. 1. Shot in May 1900 

 by Mr. G. W. Penrice. 



Mr. Penrice informs me that the country where this zebra 

 is found consists of sand-flats dotted all over with stone kopjes 

 in a state of disintegration, the flats in many cases being 

 thickly strewn with boulders. He had heard of zebras being 

 occasionally found on the top of the Chella range, 2100 metres, 

 but was unable to say to which species they belonged. 



He had first met the magnificent animal w ith which I have 

 associated his name on the Coroca Eiver, ^0 kilometres east 

 of Port Alexander, and at an elevation of only 180 m., 

 and was also told that a zebra of this species had been shot 

 some two years ago within a few miles of the sea. 



LXI. — New Peruvian Species o/Conepatus, Phyllotis, 

 and Akodon. By Oldfield Thomas, 



Conepatus arequipa, sp. n. 



Closely allied to the Ecuadorean C. quitensis, with which 

 it agrees in the great breadth of the white stripes anteriorly. 

 Size rather less than in that animal. Fur of body long and
