332 LASIOPYGA 



and the tail has no tuft like that of L. t. budgetti. From L. tantalus 

 it differs in cranial characters ; when two old male skulls are compared, 

 that of the present race is seen to be much larger in every way ; wider 

 orbits and braincase, but narrower rostrum ; intertemporal width 

 greater; nasals much longer; zygomatic width greater; palate longer; 

 tooth rows of both jaws longer by the width of first premolar ; and 

 bullae very much longer and more elevated. In fact the cranial char- 

 acters are so different it is hardly worth while to compare the skulls. 

 The upper parts like those of L. t. budgetti are much darker than L. 



TANTALUS. 



The unique type in the British Museum, an old male, was procured 

 by Mr. Boyd Alexander at Bambara on the Welle River, Central 

 Africa. 



A specimen in the Berlin Museum from the mountains west of 

 Lake Albert Edward agrees with the type above described.
