ded to, but I found time to do a little collecting in the neighbourhood now and then, 
till we left Nairobi for Mombasa the 14t» of April and the expedition was finished. 
The collection of mammals contains about 420 specimens, in size from Shrew 
to Elephant, not counting a number of extra skulls. The complete skeletons of 
many of these specimens have been preserved, even those of Elephant, Rhinoceros, 
Grévy’s zebra, Giraffe, Buffaloes ete. 
In addition to this dry collection there are also a number of specimens small 
adult mammals as well as foetuses and preparates of big ones preserved in alcohol 
and formaline for anatomical work. About 110 different species and subspecies are 
represented. A few more species were observed and are therefore mentioned below, 
although material of them was not obtained. 
The taxidermic work was done by Mr. A. JANSSON, taxidermist at the R. Nat. 
Hist. Museum, Stockholm, with assistance of natives. But I am also deeply grateful 
to Mr. R. J. Cunnrneuamu for his extremely valuable assistance especially in preser- 
ving the hides of the great mammals which thanks to his own work and that of the 
by him trained men are in a first class condition. 
Mr. A. Ss6e@reNn kindly presented two heads and three entire mammals shot 
by him to the scientific collections. I had also the pleasure of receiving a skull of 
a Hylocherus from Mrs & Mr. SanpBack-Baxer, a skull of a Jackal from Mr. Sern 
Smiru, a Pedetes from Mr. Hosiery. a Lophiomys from Mr. HENDERSON, a pair of 
tusks of a female Elephant from Mr. Woosnam. I am also obliged to Mr. Krein 
for kind help with the preservation of some skins of antelopes shot the last days of 
my stay at Nairobi. The services rendered during the whole expedition by Messrs. 
NEWLAND, TaRLToN & C:o are also gratefully acknowledged. 
The costs of the expedition were chiefly defrayed by a friend of mine, who 
does not want his name mentioned in this connection, and by His Excellency Dr. 
EmANuEL Nope. To these two gentlemen I wish to express my deepfelt gratitude 
for their generosity, but I keep also in grateful memory kind services rendered by 
other friends as well. 
My whole sojourn in British East Africa did not extend over more than about 
three months and three weeks including the time for all travels and long marches. 
I had not only to pay attention to the mammals but to birds and other vertebrates! 
as well, and collected also a number of lower animals. The deficiencies of the work 
may therefore to some extent be explained by this. 
From a biotopographical point of view the country in which this expedition 
collected mammals can be divided in a number of landscape types which offer diffe- 
rent conditions of life, and in consequence of this are inhabited by certain mammals.
