probable, in view of the distances involved and the difficulty of access 

 in one case, that these cats, like cave bears, cave rats, and racoons, 

 frequented the inner recesses of caves, a habit not previously attributed 

 to any members of the cat family in America so far as we know, 

 although Felis leo spelaea in Europe was a lion that seems to have 

 frequented caves. 



EXTENT OF THE NEW DISCOVERIES 



The specimen from Salt Eiver Cave has been deposited in the per- 

 manent collections of the United States National Museum. The 

 specimen from Saltpeter Cave will remain in the University of the 

 South, at Sewanee, Tenn. In each case the bones belong to an as- 

 sociated skeleton. We have found two individuals, and we know 

 exactly which bones belong to each, so ratios between different parts of 

 the body can be studied with significance. 



Specimen No. 1 {U. S. N. M. No. 18^62), from Salt River Cave. — 

 The skull and axial skeleton are less well represented than the ap- 

 pendages. There is a left half of the calvarium plus the left zygo- 

 matic arch. The right side of the specimen does not extend much 

 beyond the saggital crest, but includes most of the lambdoidal ridge. 

 The ossicles are still in place in the left middle ear, though the arm 

 of the malleus is broken off. Of the upper teeth only the right P* 

 is present and in good condition. There is a separate fragment of 

 the left malar. Both lower canines and a tip of an upper are present, 

 but the rest of the lower jaw, except for the left coronoid process, is 

 missing. (See plate 16.) 



There are very few good vertebrae. These include the third, fourth, 

 and fifth lumbars, the sacrum, and 5 anterior caudals. In the pectoral 

 appendage all bones are present on either the right side or the left, 

 and for the most part they are in excellent condition. The scapula 

 lacks about two-thirds of its glenoid or inferior border. The pelvic 

 appendage is similarly complete, all parts being present on either the 

 left or the right. 



Specimen No. 2, from Saltpeter Cave. — In many respects this speci- 

 men is complementary to No. 1. The skull had been broken into some 

 70 pieces, but when reassembled it was much more extensive than the 

 other. The rostral region in particular, which is totally missing in 

 No. 1, is complete in No. 2 except for teeth. The only tooth of the 

 upper jaw in good shape is P^. The upper canines are present only in 

 splinters, and the incisors are represented only by their roots. Par- 

 ticularly noteworthy is the absence of any indication of P^ on either 

 side. Part of the paracone and the metacone of P* are preserved on 

 the right side, and the left M^ is complete. The lower jaw is in fairly 

 good condition, though it, too, had to be reassembled from several
