ment of the humerus mentioned above (Cat. No. 8230) is too large to 

 lit into the upper end of the ulno-radius present. 



There are present the distal ends of two cannon bones. One 

 (Cat. No. 8238) is taken to belong to a foreleg; the other (Cat. No. 

 8237) to a hinder leg. The former is the larger. The articular sur- 

 faces are damaged, but the distance across the end was close to 92 

 mm. Across one of the articular surfaces the width is 43 mm. 

 At a distance of 75 mm. above the distal end of the bone the width 

 of the shaft is GO mm., the thickness 30 mm. The split between the 

 two divisions does not reach quite to this height. One proximal 

 phalange is present (Cat. No. 8239). The length is 102 mm.; the 

 width of the proximal end is 42 mm.; of the distal end, 33 mm. At 

 the middle of the length the side-to-side diameter is 22 mm.; the 

 fore-and-aft, 22 mm. This bone is slightly longer than the hinder 

 first phalange in the dromedary. The upper and middle diameters 

 of both species are about the same. The lower articular surfaces 

 of the fossil bone are abraded somewhat, but it is hardly probable 

 that they were expanded laterally as much as in the dromedary. 

 A right navicular (Cat. No. 8246), somewhat large for the astragalus 

 8244, has a fore-and-aft diameter of 50 mm.; a side-to-side diameter 

 of 30 mm. 



Of the left innominate bone there is a piece (Cat. No. 8240) a 

 little more than 200 mm. long. The diameters of the acetabulum 

 are 70 mm. 



The cannon bone mentioned above as a supposed hinder one has 

 each of the articular surfaces 38 mm. wide. The distance across 

 both is 85 mm. At a height of 75 mm. from the lower end the 

 shaft is only 50 mm. wide; the thickness is 25 mm. The split extends 

 a short distance above this height. 



There are present three calcanea. One (Cat. No. 8242) belongs 

 on the right side. Its total length is 155 mm.; the greatest height 

 (at surface for articulation with the fibula), 68 mm.; the greatest 

 thickness (just at the rear of the articular surface mentioned), 60 mm. 

 Another calcaneum belonging to the left side shows no important 

 difference in size or form. A third one, somewhat damaged, is 

 slightly smaller. 



A right and a left astragalus in the collection differ only slightly 

 in size. One (Cat. No. 8244), fitting pretty closely the calcaneum 

 (Cat. No. 8242), had a length along the outer face of about 80 mm.; 

 along the midline, a length of 60 mm. The width along the front 

 end is 58 mm.

 LOCALITIES, WITH DESCRIPTIONS OF TWO NEW SPECIES. 



From Prof. Mark Francis, of College Station, Texas, an enthusias- 

 tic collector of vertebrate fossils, the writer has received a cervical 

 vertebra, probably the fifth, which is of much interest. This bone,
