2 SJOSTEDTS KILIMANn.TARO-MERU EXPEDITION. 2. 



cussing the forms represented in the rich material [80 sp. (3 n. sp., 3 4 n. subsp. ); 

 417 specimens] which has been brought home by Professor YNGVE SJOSTEDT from his 

 expedition to these parts of East Africa. It is the more impossible to give a full syn- 

 opsis of the mammals occurring in the Kilimandjaro-Meru district as it appears very 

 probable, and may to some extent be proved on the following pages, that at this terri- 

 tory several different faunas meet. At least a northern and a southern, but perhaps 

 also a western. 



In some instances in the following only binomials are used, although most probably 

 the animal in question ought to have been regarded as a subspecies of another existing 

 form, but with our present knowledge it has been impossible to decide which. This 

 has made some inconsequence in the naming necessary. 



Professor SJOSTEDT has in many instances kindly given me notes about the habits 

 etc. of some animals and for this as well as for his kindness in trusting me with this work 

 I beg to express my best thanks. I wish also to express my gratitude to my friends 

 Prof. P. MATSCHIE and Dr. OLD FIELD THOMAS who kindly have given me their advice 

 in some criti 'al instances as will be mentioned below.

The youngs are to begin with almost entirely white, as has been observed already 

 by SCHILLINGS. As a white colouration cannot be regarded ancestral or original in the 

 Guerezas, the white of the young must be explained as aquired, being protective and 

 useful as well when the young is seen against the background of the mother as against 

 the white lichens (Usnea barbata) to the long swaying festoons of which the white mantle 

 and long tail of this Guereza correspond in a most remarkable manner. 



Professor SJOSTEDT has communicated the following notes from his diary: In 

 the rain forest. - - Suddenly the crowns of the trees over our heads become full 



of life. The branches are deeply weighed down under the leaps of a number of big ani- 

 mals, the foliage rustles and the whole trees appear enlivened. A glimpse directed up- 

 wards proves to me that it is flock of Colobus monkeys. In their splendid white and 

 black array with the long lateral fringes waving and the long bushy tail floating in the 

 air they throw themselves over to a tree standing near or run in a hurry along the branches 

 only to dash away in daring plunges through the air. Soon the animals become more 

 quiet, and they are not shy. Their peculiar, dull clattering or buzzing noise sounds 

 almost like a spinning wheel, sometimes like the clattering of a stork, at a distance 

 dying away as a monotonous humming noise. 



When they are resting in the often rather thin crowns of the tall trees, the hunts- 

 man is allowed to walk up quite below the tree if he is somewhat cautious. The Gue-
