smaller than any known specimen of G. darwini. Moreover, the 

 nasal arcade now described is narrower and more concave on its 

 outer face than that of G. darwini, as already observed by Roth. 

 It thus seems very probable that the animal from the Patagonian 

 cavern represents a distinct species, which must bear the name of 

 G. listed. This specific name was given by Ameghino to a fragment 

 of the first-discovered piece of skin, and the curious argument 

 which leads Roth to propose the substitution of a new name for it 

 does not affect its validity. 



It may be added that Dr. Erland Xordenskjbld has recently 

 compared his specimens from the Patagonian cavern with the 

 skull of Grypotherium darwini at Copenhagen, and finds no specific 

 difference \ No particulars, however, have yet been published. 



II. Associated Mammalian Remains. 



Felts, sp. 



A feline carnivore larger than the existing Jaguar (Felis onr-a\ 

 but about the same size as an average Tiger (F. tiyris), is repre- 

 sented in the collection by the distal half of a right humerus 

 (no. 44), a left fourth metatarsal (no. 46), and the distal end 

 of another metatarsal (no. 47). These bones have evidently been 

 buried in dust, but are in the same fresh state of preservation as those 

 of Grypotherium. They have been well described by Roth, but 

 the new figures of the humerus here given (PI. IX. figs. 2, 2 «) 

 will serve to illustrate his description better than the reduced 

 photograph already published. 



Careful comparison of these bones shows that they are un- 

 doubtedly feline ; and there is no difficulty in determining that 

 they belong to Felis rather than to the extinct MacJiarodus. A 

 humerus of M. neogasus, from a Brazilian cavern, now in the 

 British Museum (no. 1S972 6), is readily distinguished from the 

 new Patagonian humerus by the remarkable lateral compression 

 of its shaft and the much greater downward extension of its 

 prominent and sharp deltoid ridge. The humerus in all the large 

 species of Felis, on the other hand, only differs from the fossil now 

 under discussion in very small particulars. In fact, the humerus 

 and metatarsals of the existing Felis onpa are essentially identical 

 with the bones from the Patagonian cavern, except that they are 

 rather smaller. I am therefore inclined to regard the newly- 

 discovered remains as indicating a comparatively large variety of 

 F. onfa, which once lived in the temperate regions of Patagonia, 

 beyond the present range of this species. Such an occurrence 

 would be a precise parallel to that of the Cave-Lion in Europe. It 

 is well-known that nearly all the remains of Felis leo found in
