On a neio Guilafjo from Oerman East Africa. 1G7 



XIII. — .1 nexo Galago from German Enst Africa. 

 By Dr. EiNAii LoNNBiiRG, F.M.Z.S., &c. 



The R.Nat. Hist. Museum, Stockliolin, lias recently obtained 

 from Mr. K. Kittenberger a Galago wliicb was collected at 

 Ukina, near tScliirati, east ot Victoria Nyanza, German East 

 Alrica, in March 1911. The specimen is an old male with 

 especially the upper canines well worn. It is remarkable 

 lor its lii^ht-coloured fur and its large and heavy skull. So 

 far as I know, it is not described, and I propose to name it 



Galago argentalus, sp. n. 

 With regard to certain rdative dimensions, tliis Galago 

 belongs to the Otole7nur-gioup, and, in most cases, tlie 

 difference is quite plainly jjronounced : the diameter of the 

 orbit (20 mm.) is larger tlian the distance from the anterior 

 margin of the foramen infra-orhitale to the gnathion (about 

 18 mm. to the most prominent point) ; the length of the 

 nasals (27'5 mm.) is subequal or a little longer than the 

 distance between the anterior brim of the orbit and the 

 gnathion (27 mm.); the length of the ears (about 51 mm.) 

 is less than the length of the hand (5o*5 mm.), and also less 

 than two-thirds the length of the head (the greatest length 

 of the skull being 8-1 mm.). 



The general colour is very light grey, and may be called 

 light silvery grey. It is very little darker along the back, 

 and in some lights a very faint bufiish tinge may be dis- 

 cerned in some places. Tlie forehead has a sliglit brownish 

 tinge due to brown tips to the hairs. The outer sides of the 

 legs are coloured like the sides of the body. The feet are 

 pale brownish mixed with pale grey. The sides of the head 

 and neck are dirty white. Tbe lower parts are pure white 

 along the middle line", somewhat greyish towards the sides. 

 The tail is white, rather sharply set off from the grey of the 

 back and very little obscured by dark tips to the hairs on the 

 proximal two-thirds, a little more dusky towards the end. 



The fur is soft and thick. Its length on the middle of the 

 back is about 35 mm. More than the proximal half of this 

 length is very dark grey, but the distal portion is white. 

 The scattered long hairs produce the silvery-grey colour by 

 being blackish with or without white subterminal rings. 

 Along the middle of the lower parts and on the inner sides of 

 the thighs the fur is pure white to the base. On tiie sides of 

 the belly and breast the fur is lead-grey at the base. 



Length of head and body (approximately from skin) 

 36 cm. (probably a little more in the flesh). Length of tail 

 about 4.2^ cm. Length of ear (softened) about 51 cm. 

 Length ol hind foot (softened) 95 mm.
