This form was described as a subspecies of G. moholi, but as this 
is a synonym of G. SENEGALENSIS a West African species, it was 
necessary to remove it from that category, and as it is evidently not a 
* subspecies of any East African Galago, I have given it specific rank.

In a collection of mammals lately received at the American Mu- 
seum of Natural History, from Colombia, were a number of examples 
of this species of different ages obtained at La Palma, Huila, at an 
elevation of 5,500 feet. These specimens would seem to prove that 
the type in the British Museum was in immature pelage, and that 
the adult is a gray animal with the head bistre. Some specimens are 
like the type, and one is intermediate between the type and the adult, 
with the gray appearing on the lower back, rump and tail. The adult 
may be described as follows: 
Lagothrix lugens, adult male. Top and sides of head sepia; fore- 
head pale wood brown; occiput and hind neck dark mars brown; 
upper part of back mouse gray tinged with brown, rest of back, rump, 
outer side of legs and feet dark smoke gray; outer side of arms 
similar to upper back; hands like arms with a pale brownish patch 
below fingers; chin pale cinnamon; lower part of throat and upper 
part of chest chestnut; flanks gray like back; rest of under part 
of body, under side of arms and legs jet black; tail above gray like 
rump, beneath black. The skull has the same peculiar nasals with the 
anterior half projecting at a right angle to the posterior portions.* 
*As the last two species became known to the author only lately, it has 
not been possible to arrange them in the Appendix in their proper order.
