Ti/pe. Old male. B.M. no. 4. 7. 4. 43. Original number 

 1867. Collected 24th April, 1904, by A. Robert. Presented 

 by Oldfield Thomas. One specimen. 



This cat clearly belongs to the F. Wiedn group, as defined 

 in my paper on the spotted tiger-cats of Brazil*; but it is 

 distinguished from any that I have seen by its large buUai 

 and comparatively narrow and parallel-sided brain-case, 

 beyond and behind which the broad lambdoid and mastoid 

 ridges conspicuously project. The forward direction of its 

 nape-hairs is unusually smooth and deiinite, and its light ear- 

 patclies are not so white as in specimens from other localities. 



Dr. Goeldi has given a pretty figure of tlie head of this 

 cat in his recent work on the mammals of Pard f . 



Rhijndoviys inctor^ sp. n. 



A medium-sized species allied to R. venezuelce. 



Size rather less than in R. venezuelce^ markedly greater 

 than in R. dryas. Fur close and crisp ; hairs of back about 

 6-6*5 mm. in length. General colour above dark fulvous 

 brown, rather more rufous on the sides. Belly and inner 

 sides of limbs white, not very sharply defined, the liairs 

 along the i^ides of tlie belly grey basally, the others white 

 to their roots. Ears rather short, pale brown. Outer side of 

 arms and legs dull fulvous; hands and feet thinly haired, 

 "whitish, the metatarsals with indistinct browner patches along 

 their outer halves. Tail fairly well haired, the tip with a 

 well-marked pencil whose hairs attain 12 mm. in length ; 

 uniformly brown throughout. 



Skull very similar to that of R. venezuelce, but smaller. 

 Brain-case rounded, its profile convex ; supraorbital edges 

 sharply defined, but not heavily ridged ; zygomatic plate not 

 projected forward ; palatal foramina well open, not reaching 

 backwards quite to the level of the front of lu^ ; hnWsd small.
