 RANGIFER MUSCATINENSIS? Leidy. 



In the collection, with McAdams' number 11, i.s a tooth of a Rangi- 

 fer, apparently an upper right fourth milk molar (Cat. No. 9006). 

 This is referred provisionally to the species named above. The 

 length of the crown near the outer face is 17 mm.; the width is 

 13 mm.

 In the collection made by Mr. McAdams there are found 11 molar 

 teeth, upper and lower, which are to be referred to the species de- 

 scribed by Gidley, from a cave at Corriganville, Maryland. Of 

 these 11 teeth, 3 belong to the upper jaw ; the remainder to the lower. 

 The! upper teeth consist of second molars, right and left, and a left 

 third molar, probably all of the same individual. Of the lower teeth 

 there are first molars, right and left; a right second molar; a left 

 third molar, practically complete, and part of that of the right ; all of 

 which, except probably the last, may have belonged to the same in- 

 dividual to which the upper teeth belonged. All these have the cata- 

 logue number 9007. Then, there is another last molar which is much 

 more worn than those above recorded (Cat. No. 9008). One of the 

 oth(^' somewhat damaged teeth is determined as a lower right first 

 molar (Cat. No. 9008). The height of these teeth is given in the 

 following table of measurements. It varies, of course, in the same 

 tooth with the degree of wear, and perhaps with the degree of de- 

 velopment of the base. The width is taken on the flat face of the 

 tooth and about 25 mm. above the base. The thickness is the greatest, 

 taken at the base. 



No differences that are certainly of specific importance are 

 observed on comparison of the upper second and third molars of the
