specimen has there been noted any suggestion of the form seen in 

 no. 20052, so that there was no common tendency to develop this 

 type of horn. 



For the present it is desirable to recognize this form as distinct 

 from other species and probably nearest to Meryeodus. 



Two jaw fragments with teeth from locality 2057, in the Barstow 

 syncline, represent a form near Dromomeryx, but apparently more 

 advanced than any described American form. 



Fig. 136. Dromomeryv or Cervus?, n. sp. Dm, and M 1? no. 21218, natural 

 size. Barstow Miocene, Mohave Desert, California. 



Fig. 137. Dromomeryx or Cervus?, n. sp. Inferior teeth, no. 21219, natural 

 size. Barstow Miocene, Mohave Desert, California. 



A fragmentary specimen, no. 21218 (fig. 136), shows Dm 4 and M t . 

 Both teeth resemble Dromomeryx in general form. They have the 

 exceedingly rough enamel, the inner cusp between the protoconid 

 and hypoconid pillars, and the shelf of the cingulum found in 

 Dromomeryx. The dimensions of M, are near those of specimens 

 of Dromomeryx from the Snake Creek beds of Nebraska. They differ 

 from Dromomeryx in entire absence of the palaeomeryx fold, and in 

 the greater length of M x than in the Dromomeryx specimens known 

 to the writer.
