W. BOYD DAWKINS ON THE MAMMAL-FAUNA 



The Wild Cat (Felis catus ferus). Three lower jaws from the 

 Cave-earth and one from the stratum above the stalagmite belong 

 to the Wild Cat. One is remarkable for its massive character and 

 large size, in which points it far surpasses any of the recent 

 Wild Cat's with which I have had the opportunity of comparing it. 

 The thickening of the inner alveolar border, and the implantation 

 of the molar series in the outer edge, prove that this feline does not 

 belong to the Felis coffer described by Mr. Sanford and myself in 

 the Palseontographical Society's Memoirs (" British Pleistocene Mam- 

 malia," part iv. p. 121). The rest are also larger than the recent 

 Wild Cat's, as may be seen by the following Table of measurements

The Spotted Hyarna (H. crocuta). — The remains of the Spotted 

 Hyaenas consist principally of jaws and teeth of all ages ; and those 

 from the Cave-earth are, for the most part, in fragments. 



Two skulls, a scapula, and a cervical vertebra were obtained from 

 the lied Sand. On a comparison of the two skulls with those of the 

 recent H. crocuta in the College of Surgeons, which belonged to the 

 collection made by Captain Gordon Cumming in S. Africa, I am un- 

 able to detect any points of specific value. If any thing, the larger 

 of the two fossil skulls, possessing the sutures and teeth of the 

 adult, is smaller than the larger of the two recent, as may be seen 

 from the following measurements (in inches) : —
