The spelaean teeth, as may be observed from the figures given 

 above, are, on the whole, larger than those of the Spotted Hyaena 

 which are in our museums ; but the minimum measurements of the 

 former fall within the maximum measurements of the latter. I am 

 unable to detect any differences of form between the two which are 

 constant. They are related to each other in the same manner as 

 those of the spelaean are related to those of the living Lions. 



The articulation of the scapula measures 2 x 2*5 ; and the cir- 

 cumference of the neck is 4*5 inches. 



In reviewing the whole evidence at my command as to the relation 

 of the Cave-hyaena to the living Spotted Hyaena (B. crocuta), I am 

 unable to recognize any constant differences, and therefore believe 

 them to be specifically identical. 



Fox (Canis vulpes), Wolf (Canis lupus). — The remains of the Pox 

 and Wolf offer no points worthy of special notice. 



Bear (Ursus ferox? U. arctos?). — The remains of Bear, consisting 

 of two jaws, 39 teeth, and 32 bones, belong to young adults and 

 very old individuals. Some of the teeth agree with those of the 

 Grizzly Bear as defined by Prof. Busk (Trans. Royal Soc. 1872, 

 p. 532 et seq.), while others agree closely in size and form with 

 those of the Ursus arctos. I am unable to lay hold of characters by 

 which these closely allied forms, both recent and fossil, are dis- 

 tinguished, so far as relates to their dentition ; and I feel inclined to 

 hold the view, lately taken by Mr. J. A. Allen *, that the two living
