Specimens of the true L. albigularis from a number of places 

 are in the Collection of the British Museum varying but little from the 

 typical style. The type was purchased alive in Bombay, and was said 

 to have come from Madagascar, and probably did come from some 

 part of East Africa, and if this supposition is correct, the monkeys 

 of this species from the East African coast would represent the typical 

 style. The species is found across the continent from the east coast 

 to the Gold Coast, on the west (Pel) and from Nyassaland to the 

 Transvaal. 



The type of L. erythrarchus Peters, is in the Berlin Museum. It 

 came from Inhambane, south of the Zambesi, and is a young animal 

 not separable from L. albigularis. The type of L. monoides I. Geoff., 

 is in the Paris Museum and exactly resembles L. albigularis, in fact 

 there is no difference whatever in their appearance. Unfortunately 

 the skull is in the specimen, so no comparison could be made. 



According to Grant, as quoted by Thomas and Schwann (1. c.) 

 in the Drakenberg Range, north east Transvaal, this monkey is "com- 

 mon, but difficult to obtain on account of its wariness. It inhabits the 

 deep kloofs in the depths of the forest, seldom visiting the open parts."
