1286 MESSRS, O. THOMAS AND E. C. WROUGHTON ON [Mar. 19, 



" So far as I could learn, the District has never been surveyed, 

 so that the altitude of Coguno, or other places, is unknown, 

 but probably no part exceeds 1000 ft. The actual position of 

 rivers and localities can only be roughly estimated. 



" Throughout my stay the climate was delightful ; the average 

 temperature being around 80° in the shade, occasionally reaching 

 88° ; it being the dry season, there was little rain. 



" The following species were not obtained but exist at Coguno, 

 and the native names may be of interest. They are : 



'' Lutra ■ Shalu. 



M'ungos gracilis Lengo. 



Thryonomys swiyidei-enianus ... Shleti." — C. H. B. G. 



1. Papio porcarius Bodd. 



Flat skin. 



" Native name, ' Infeni.' 



" This species was not seen in the neighbourhood of Coguno 

 Camp, but is said to be common to the North and West. The 

 flat skin sent was obtained from a native who killed it some 

 20 miles to the northward of my camp." — C. H. B. G. 



2. Cercopithecus pygerythrus erythrarchus Peters. 

 S. 1492, 1594. $. 1493, 1599. 



Mr. Pocock informs us that he considers Peters's erythrarchus., 

 of which these are topotypes, should be ranked as a subspecies of 

 pygerythrus F. Cuv. 



" Native name, ' Makaku ' or ' Ihow.' 



" Common and inhabiting the denser forests where it lives on 

 the wild fruit and berries. Never observed in large troops ; single 

 old males were sometimes seen, but were usually unapproachable. 

 They are at all times wary and extremely difficult to secure. 

 Cercopithecus alhigularis exists in the district, but is very rare 

 and local and even the natives were unable to obtain me speci- 

 mens ; it is known to them as ' Glanglanu '." — C. H. B. G. 



3. Galago granxi, sp. n. 



S. 1617, 1618, 1619, 1660, 1662. $. 1517, 1653, 1663. 



A member of the moholi group, with an unusually bushy black- 

 tipped tail. 



Fur fine and soft, about 15 mm. in length on the back. General 

 colour above drab-brown, rather darker than Ridgway's " drab." 

 Under surface cream-buff, the basal three-fifths of the hairs slaty. 

 Lio-ht nose-line and black orbital patches as in Q. moholi. Outer 

 side of fore limbs light drab, lightening to white on the hands ; 

 inner side like belly. Hind limbs as usual dull cream-buff 

 throughout, rather duller than on the belly. Tail long, unusually 

 bushy, the hairs attaining a length of 20-25 mm., those of true 

 moholi but little more than half this length ; in colour the basal 

 three-fifths of the tail is drab-brown like the body, gradually 

 darkening terminally to blackish brown.
