There are* three specimens of this species in the British Museum 

 from the east bank of the Loangwa River, collected by S. A. Neave at 

 an altitude of 2,200 feet, one from Limondi on the boundary between 

 the English and Portuguese territories, and one from North Basi- 

 hindo, Chiyaka District, Angola, West Africa, collected by Dr. F. C. 

 Wellman. They closely resemble each other, giving the impression 

 of a yellow monkey speckled on head, middle of back and rump with 

 black, but the rings rather indistinct on flanks. By having the red 

 patch beneath the tail at the root, the species shows its relationship to 

 L. PYGERYTHRA, but it bears no resemblance whatever to that animal 

 in its general coloration, and in fact is far too much of a yellowish 

 hue to be compared with any other species of the genus. It doubtless 

 is a dweller of the forests on the watershed from the Loangwa River 

 westward to Angola. It is a large thick-set animal with rather short 

 limbs and long tail.
