70 Mr. O. Tliomas on a new Species of 



Emin says of this animal : — " Iride nigerrima. This single 

 specimen found among the high dry grasses. Runs like a 

 Gerbille. Native name ' Gosso.' " 



Further examination has convinced me that my reference 

 of this specimen to M. rufescens was incorrect, and that the 

 considerable diflference in the general body-colour is of, suffi- 

 cient importance to distinguish the two forms. 



Dr. Gregory's specimen of Afacroscelides, above referred to, 

 obtained by him at Kibwezi, British East Africa, is itself of 

 some interest, as, occurring in the neighbourhood of the 

 original locality of JI. rufescens, it differs from that animal 

 in being of a uniform dirty slate-colour below, with nearly 

 or quite obsolete face-markings, and of a generally much 

 darker tone of colour. In all other respects, liowever, it 

 appears to be identical, and I am therefore disposed to 

 consider it as being possibly a melanistic example of 31. rufes- 

 cens, as its coloration seems so abnormal. Should this prove 

 to be the case, it increases the probability, already suggested 

 by Huet *, that Peters's M. fuscus, coloured somewhat simi- 

 larly, is also founded on a melanistic individual of the ordinary 

 Mozambique form. The dental peculiarities oi M. fuscus, as 

 described by Peters, seem merely to be due to his having 

 mistaken milk for permanent teeth. 



TX. — On a new Species of Armadillo from Bolivia. 

 By Oldfield Thomas. 



The British Museum owes to the kindness of the well-known 

 naturalist Prof. W. Nation, of Lima, a specimen of an arma- 

 dillo belonging to the restricted genus Dast/pus, but not refer- 

 able to any of the previously known species of the genus. 

 I would propose to term it, in honour of its donor, 



Dasypus Nationi, sp. n. 



Intermediate in size between D. viUosus, Desm., and 

 D. veUerosus, Gray f, to the latter of which it is probably 

 most nearly allied. Cephalic shield very broad and short, 

 its breadth slightly exceeding its length ; its scales pro- 

 portionally large, smooth, ami but little sculptured, their
