JJab. Gambi, V/elle li. 



Type. Adult male. Original number G. B. G. 92. Col- 

 lected 31st January, 1906, by Capt. G. B, Gosling. One 

 specimen only. 



Monbuttu name " Monbongolo.^' — G. B. G. 



We have named this handsome species, the type of a most 

 distinct new genus, in honour of its captor, Ca|)t. Gosling, 

 whose untimely death has deprived science of one who took 

 an intense interest in the collection of ^Mammalia, and who wo 

 had hoped would have taken up their study at home with the 

 same zeal that he devoted to their capture abroad. 



Thamnomys huru, sp. n. 



A Thamnomys of the venustus-rutdans group, but markedly 

 smaller than either of those species. 



Fur of back rather long (10 mm.) and silky. General 

 colour above dark brown, grizzled with yellowish buff, below 

 white, more or less stained with pinkish buff. 



Whole upper surface of body a dark brown grizzled witli 

 orange-buff (the hairs dark slate-eoluur, a large proportion, 

 almost all at tlie root of the tail, tipped with orange-bufF, the 

 remainder with very dark brown, almost black), paling rather 

 suddenly at the sides into the white of tlie belly (the hairs of 

 which are white to their bases), a certain amount of orange- 

 or pinkish-buff suffusion modifying the white colour of the 

 under surface of the body, espicially on the chest and on 

 inner side ot limbs. Tail dark, regularly but sparsely clothed 

 on proximal half with very short brown hairs, thence distally 

 length of hairs increasing until at tip they measure b-'o mm. 

 in length ; rings of tail 20-21 to the inch. 



The skull much smaller tlian in rutiUins ; comparing with 

 a specimen of that species of like age from the (Jiimeroons 

 the skull is one lifth shorter and proportionally narrower and 

 the upper molar series is 5'5 mm. only, instead of G"2 mm. 

 The Hrst and second molars show the characteristic third
