44 EINAE LONNBEEG, MAMMALS COLLECTED BY THE SWEDISH ZOOLOGICAL EXPEDITION ETC. 



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: 0. agisymbanus, lasiotis, panganiensis, and hadius, while 

 Otogale embraced 0. garnetti, crassicaudatus, monteiroi, and Icirhi. 



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 (PI. 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 

 yellows n:o 2 according to » Repertoire 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 (Repert. 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. 



Total length about 62 cm. Tail about equal to head and body in length. 



Greatest length of skull 61 mm. 



Basicranial length 49 » 



Greatest zygomatic breadth .... 41 $ 



Palatal length 23 * 



Length of upper molar series .... 19,5 » 



These skull measurements agree closely with those recorded by Elliot for a 

 species described by him under the name Galago Mndei.^ 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 O. 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 20 V^ cm., 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 0. hindei are also said to be »Uke head» viz. pale 

 wood brown washed with darker brown. 



Otolemur panganiensis Matschie from the Kilimanjaro district has the tail con- 

 siderably longer t han head and body and a much larger skull attaining a maximum
