Subspecies of Paraxerus flavivittis, Peters. 311 
In another way the fine series from Lumbo is of great 
utility, since it enables us to appreciate the constancy of 
certain features in the pattern (apart from colour) of the coat. 
Peters’s figure shows an animal with very definite facial 
markings in the region between and below the eye and the 
ear, and with a single light-coloured, very broad, long, and 
well-defined stripe bordering the back on each side. These 
features are faithfully reproduced in each of the Lumbo speci- 
mens, and there is no reason to doubt that they are essential 
and charaeteristic elements of the coat-pattern in both P. f. 
flavivittis and P. f. mossambicus. In other species of Para- 
werus, as now understood, the facial markings are quite incon- 
spicuous or absent, while the lateral dorsal stripe on each side 
is reduced to such a degree that it is almost imperceptible. 
Two specimens in the British Museum come from localities 
considerably to the north of Lumbo (15° 8.) and Mossimboa 
(11° 8.), one coming from Kilwa Kisiwani (9° §.), the other 
irom Mombasa (4° 8.). Differing from each other, as well as 
from true flavivitiis and f. mossambicus, the northern specimens 
appear to represent two subspecies of flavivittis, interesting 
both as members of a continuous series of geographical races 
and as subspecies which tend to lessen the gap between true 
flavivittis and more normal species of Parawerus. ‘They may 
be described as follows :-— 
Paraxerus flavivittis exgeanus, subsp. n. 
Hah.—Kilwa Kisiwani, ex-German Kast Africa. _ 
Type.—An adult male in bright pelage (B.M. 19. 4. 14.3), 
collected March 8, 1918, and presented to the British Museum 
by Major C. H. B. Grant. 
This form differs from both the southern subspecies by 
having the lateral dorsal stripe on each side much narrower 
and the thoracic ochraceous mantle much less developed. 
Upper surface (top of head and the whole back to root 
of tail) clothed with a fine grizzle of black or dark brown 
and dull ochraceous, the general effect being, in the lumbar 
region, near mummy-brown. On the top of the muzzle and 
towards the root of the tail the ochraceous hair-tips are more 
abundant, sensibly brightening the general colour ; in the 
neighbourhood of the shoulders and withers they are still 
more extensively developed, producing a perfectly distinct 
though not a conspicuous dorsal mantle. ‘The lateral stripe 
on each side of the back is much narrower and somewhat 
shorter than in mossambicus ; where broadest it measures no 
more than 5 mm., instead of 9 or 10 mm. as in the southern 
form ; the colour of the stripe is white posteriorly, faintly
