INTRODUCTION 



The collections of pangolins and aard-varks made by Messrs. 

 Herbert Lang and James P. Chapin, while functioning as the American 

 Museum Congo Expedition, are of exceptional value in that the spe- 

 cies represented were secured in sufficient numbers to enable one, 

 apparently for the first time, to gauge the range of variation occurring 

 within geographically limited populations of these species. 



There have been many revisions of the Manidae between that of 

 Sundevall in 1843 and that of Frechkop in 1931, and current nomencla- 

 ture synthesizes their conclusions. Thus, the two African arboreal 

 species and the giant pangolin are now commonly recognized as generical- 

 ly differentiated and without subspecies, though exhibiting great indi- 

 vidual variation in some characters, a status which the ninety-five scaly 

 anteaters of the collection does not affect. 



The Orycteropodidae, to the contrary, appear to present noteworthy 

 localization of character combinations within areas not far separated.
