garnetti, viz. Otogale, in the following way: In Otolemur the orbit is much broader 
than the distance between the gnathion and the anterior margin of foramen infra- 
orbitale. In Otogale these distances are about equal. In Otolemur the nasals are at 
least as long as the distance between the gnathion and the anterior brim of the 
orbit, in Otogale shorter. In Otolemur the ears are shorter, in Otogale longer than the 
hands. In Otolemur the ears are much shorter than two thirds the length of the 
head, in Otogale about equal to this latter dimension. 
According to this definition the subgenus Otolemur included at the time men- 
tioned the following species: O. agisymbanus, lasiotis, panganiensis, and badius, while 
Otogale embraced O. garnetti, crassicaudatus, monteiroi, and kirki. 
The present species is evidently a member of the subgenus Otolemur the dia- 
meter of the orbit measuring 17 mm. while the distance between the gnathion and 
the anterior margin of foramen infraorbitale is 14,5 mm. The length of the nasals is 
19 mm. while the length of the preorbital portion of the skull is 18,3 mm. The ears 
are short and naked. General colour (Pl. IV fig. 1) of the upper parts pale greyish 
brown, somewhat darker on head and upper neck, outside of limbs more chamois. 
Throat and lower side of neck pale with an ochre yellow tinge or similar to »maize 
yellow» n:o 2 according to »Répertoire de couleurs>. Inside of fore limbs and under 
parts of body dirty white, inside of hind limbs more brownish. Hands and feet dark 
brown inclining to blackish. Tail rather dark brown above, gradually darkening to 
blackish brown towards the distal third, pale snuff brown on the lower side. The 
fur on the back very soft, 23—25 mm. dark slate-coloured for the greater part with 
broad subterminal rings similar to »chamois» n:o 1 (Répert. de coul.) and with dark 
brown tips which in the majority of the hair is short, but in the longer hair are 
longer than the chamois-coloured rings.

These skull measurements agree closely with those recorded by Euuior for a 
species described by him under the name Galago hindei.' This species which has 
been collected at Kitui, Athi River, Brit. East Africa, must, however, in other respects 
differ rather widely from the one now described. The total length of G. hindei is 
said to be about 57,5 cm., and the tail is indicated to be 37 cm. It must thus have 
a very short body, only about 207/2 em., and it is certainly much shorter than the 
tail which is stated to be »very long», »almost white (»above pale wood brown, 
beneath whitish»). The hands of G. hindei are also said to be »like head» viz. pale 
wood brown washed with darker brown. 
Otolemur panganiensis Marscuie from the Kilimanjaro district has the tail con- 
siderably longer than head and body and a much larger skull attaining a maximum
