The point of the permanentcanine has just begun to piotrude from the socket ; thethree deciduous molars are retained, the last having theform of the sectorial tooth : these are succeeded and dis-placed by the first three molars of the adult, which havethe conical form : the permanent sectorial tooth, s, is deve-loped behind these, and rises behind the deciduous sectorial,which it does not displace ; it is developed earlier than theanterior permanent molares. 158 Fi(,. Lower jaw of young HycBiia spelcBct, ^ nat. size. Kents Hole. A great proportion of tlie skeleton of the Hyeena speltsahas now been recovered from the different locaHties of thatextinct species in Enghmd, The larger bones of the extre-mities found in Rentes Hole are fractured, as in the Kirk-dale cave; but the smaller bones, as the astragalus, calca-neum, metacarpals, and metatarsals, are, for the most part,remarkably perfect. They differ from their analogues inthe skeleton of the Hyeena crocuta chiefly in their largerand more robust proportions : the scapula apjsears to berather narrower in proportion to its articular extremity;the deltoid crest of the humerus is longer and stronger. In the numerous specimens of the fossil Hysena fromBritish localities, which I have examined and comparedin public and private collections, I have not hitherto de-tected any characters indicative of a species distinct fromthe Hyeena spelaa ; the differen
