MAMMALS COLLECTED BY DR. A. DONALDSON SMITH DURING HIS 



expedition to lake rudolf, africa. i 

 By Samuel N. Rhoads. 



In the following annotated list of the mammals collected by Dr. 

 A. Donaldson Smith during his African expedition of 1894-95 

 across Somaliland to Lake Rudolf, I have included all the species 

 coming under my observation which were brought back by Dr. 

 Smith to Philadelphia. 



The greater part of the collection was most generously given to 

 the Academy of Natural Sciences of Philadelphia, but a large part 

 of the skulls, mounted heads and skins of the larger game have been 

 reserved by Dr. Smith, and at present form an exhibition at the 

 University of Pennsylvania. Those species in the list not repre- 

 sented in the donation to the Academy are preceded by an aster- 

 isk. 



The entire collection represents 50 genera and 77 species,^ seven of 

 which are here described as new. 



Dr. Smith is to be congratulated on having brought to Philadel- 

 phia by far the largest, most comprehensive and best preserved 

 faunal collection of African mammals ever acquired by an Ameri- 

 can institution, and not only many species, but several genera are 

 for the first time made accessible to students on this side of the 

 Atlantic. 



Owing to the almost total lack of specimens in this country for 

 comparison, and the widely scattered literature relating to African 

 mammalogy, the author has been severely handicapped in his study 

 of the collection, and it is hoped that the paper, as now presented, 

 will be judged accordingly. 



1 At the request of Dr. Smith this paper was originally prepared for 

 publication in his forthcoming book on the Lake Rudolf expedition. Less 

 than three months were alloted the writer for its preparation. The mss. was 

 subsequently returned, with other papers of scientific character intended for 

 the work, on account of lack of space and was then accepted for publication 

 in the Proceeoings of the Academy of Natural Sciences of Philadelphia. 



^This includes four genera and live species of bats, which have been worked 

 up by Dr, Harrison Allen in a separate paper, viz : Megaderma frons, Meg- 

 derma cor, Nycteris capensis, Scotophilus miaiinus and Adelonyderis sp. ?
