LASIOPYGA 367 



all it is decidedly yellow not 'gray.' On the hind neck the rings are 

 paler (than albigularis, with which it is compared), more whitish. 

 Shoulders and arms are wholly black in the Kilimandjaro monkeys, 

 except that the inner side of the upper arm is more or less ashy gray, 

 but the fore arm is intensely black, not specklel as in the typical 

 albigularis according to Pocock. The legs are black, speckled with 

 ash gray. Red hairs at the root of the tail, and in the ischiopubic 

 region, are found in all ages and both sexes, but less in the adult male 

 than in others. Chin and throat white, (in younger specimens with 

 soft wavy hairs) ; on the sides of the neck this white area passes into 

 a broad iron gray speckled collar, which, however, leaves a broad 

 dark band on the hind neck free, and with its black hairs sparingly 

 ringed with whitish or pale yellow, contrasting against the iron gray 

 collar. The white of the throat does not extend to the inside of the 

 upper arm as in the typical form, according to Pocock, and it is 

 rather sharply defined from the gray ventral surface. On the back 

 the reddish yellow is quite dominating on the lumbar and sacral 

 regions, and from there extending more or less forward, and on the 

 tail, flanks, etc." 



"The differences, although slight, appear to indicate a separate 

 geographic race or subspecies, which I name after the type locality 

 Kibonoto." 



The above is the description given by the Author. From his 

 quoting Pocock's description of L. albigularis and comparing his 

 specimen with that only, it is to be inferred that he has no personal 

 knowledge of that species and therefore is not able to speak with any 

 certainty as to whether his examples are really different or not. L. 

 ALBIGULARIS has 3. very wide range and although it may not have been 

 stated before to be a resident of Kilimanjaro, it has been taken in 

 rather close proximity, such as the Nairobi forest, etc. It is difficult 

 to ascertain, from the rather unsatisfactory description, whether this 

 Kilimanjaro monkey is even subspecifically distinct from L. albigu- 

 laris, but, not having seen it, I leave it with the rank its describer 

 gave it. Unfortunately no mention was made of the measurements, 

 or characters of skull or teeth. Herr Lonnberg gives the following 

 short account of the animal : "This monkey is, according to Sjostedt, 

 very common even in the rain forest. It lived in greater or small 

 bands in dense forests in groups of trees and in the farms, and similar 

 localities. When caught they remain wild for a long time and are 

 difficult to tame, as they keep their angry disposition and are unre-
