considerable bleaching takes place, especially on tlie tail, so 

 that old hairs of jacksoni may have the colour of those of 

 fresh capitis, while in the latter again the yellowish rings 

 may bleach nearly to white. 



Paraxerus ochraceus, Huet. 



This species is characterized by having an indistinct 

 whitish line on the flanks and by its under surface (especially 

 its throat) being whitish, as compared with the entire absence 

 of a flank-line and the bufFy or ochraceous under surface of 

 P. aruscensis and its allies. 



The type came from Bagamoyo, and to the typical race I 

 assign a specimen from Mrogoro, Usagara, about 100 kilo- 

 metres inland, which was obtained and presented by Emin 

 Pasha. This specimen has the yellowish-ochre tinge on the 

 back and the "jaune d'ocre pur" on the upper surface of the 

 feet described in the type, and Mrogoro is so near Bagamoyo 

 and on the trade-route to the interior (so that the type may 

 even have been brought from Mrogoro) that I have no hesi- 

 tation in making this reference, even though the next form 

 comes from a locality that, like Bagamoyo, is on the coast. 

 The latter does not, however, agree nearly so well with 

 Huet's description. 



Paraxerus ochraceus salutans, subsp. n. 



Like true ochraceus in general characters, but the colour 

 above more olivaceous, the yellowish reduced throughout. 

 Hands and feet dull grey, mixed bufFy or ochraceous buffy, 

 not the clear rich ochraceous found in the typical form. 

 Throat and chest pale buffy whitish. Tail-hairs tipped with 

 buffy. 



Skull and teeth rather larger than in true ochraceus. 



Dimensions of type (measured in skin) : — 



Head and body 172 mm. ; tail 158; hind foot (wet) 38; 

 ear (wet) 15. 



Skull : greatest length 40"5 ; condylo-basal length 36"3 ; 

 upper tooth-series exclusive of />' 6"2. 



Hah. Dar-es-Salaam, coast of German East Africa. 



Type. Adult male. B.M. no. 79. 11. 12. 10. Collected 

 by Sir John Kirk. Two specimens. 



Paraxerus ochraceus electus, subsp. n. 



General colour of the same rather greyish olivaceous as in 

 P. 0. salutans, but the grizzling far tiner, owing to the light
