notably in the absence or extremely rudimentary character of the 

 postero-internal basal denticule in the lower carhassial, as well as 

 in the entire absence of the anterior accessory cusps in the upper 

 and the first two lower premolars, it approximates to the most dif- 

 ferentiated form, now represented by the Cape Hysena. No other 

 species of Hyaena is known in which there is such a remarkable com- 

 bination of characters shared by such divergent forms.

HriENA FELiNA, uob. (PL YI. fig. 6.) 



The history of the specimen * on which this species is founded is 

 thus given in the ' Paleeontological Memoirs ' f in the index to the 

 unpublished plate K (headed Felis cristata by an error), in explanation 

 of the figures 1, la, 16, Ic : — " Four difi'erent views of an imperfect 

 cranium from Mr. W. Ewer's collection. The left maxillary bone 

 with the teeth is absent ; but the portion was found after the draw- 

 ing was made, and has been added to the specimen in the British 

 Museum." 



Dr. Falconer entered the left maxillary bone alluded to here as 

 belonging to Hycena in the British-Museum Catalogue. The skull 

 as it now stands is deficient only in the zygomatic arches, and evi- 

 dently belongs to an aged individual. The facial portion has 

 suffered a crush anteriorly, and is slightly distorted in consequence. 

 The incisors have been removed. The crown of the canine has been 

 broken off, but its base shows it to have been proportionatelv 

 stronger than the corresponding tooth of Hyaena; this, however, may 

 be an individual variation. There is no indication whatever of the
