XLIV. — On a new Species of Atherura. discovered bi/ Copt. 

 Guy Burrows on the Congo. By Oldfield TllOMAS. 



The British ]\Iuseum owes to tlie generosity of Capt. Guy 

 Burrows, lute Comiiiissioiier of the Aruwimi district of the 

 Congo, tlie skeleton of an Atherura obviously different from 

 any described species. Tlie skin has unfortunately been lost ; 

 but in tliis group the chaiacters of the skull afford the chief 

 di>tinguishing niaiks, and 1 have therefore no hesitation in 

 describing the species as new. It may be called 



Atherura Burrowsi, sp. n. 



Size even less than in A. centralU, Thos., of IMonbuttu *, 

 itself distinguished from the West-African A. africanu by its 

 smaller size and less intlated skull. Nasals very small, short, 

 narrow, jjaiallel- sided. Frontal region not iuBated at all, 

 scarcely concave medially. Supraorbital edges rounded, 

 parallel, without postorbital pnjections. Interparietal large^ 

 inojecting iar forward, so tiiat the median j)arietal suture is 

 only about one third the length of tlie antero-posterior 

 diameter of tiiC interparietal ; in A. nfricana and centralis 

 ihe two measurements are about equal. A vacuity present 

 in the middle line of the palate hallway between the palatal 

 foramina and the jjreniolars. Middle line of palate not raised 

 up into a central ridge, and the basioccij«ital ecjually smooth. 



Milk-premolar still in place, but the last molar up and
