Family TRASULIDyE (pt. ii. p. 150). 



Genus LEPTOMERYX, Leidy \ 



The cheek-dentition is almost or quite indistinguishable from that 

 of Prodremotherium{^t ii. p. 150), on which grounds Cope ^ has pro- 

 posed to unite the two genera. Leptomeryx is, however, distin- 

 guised by having four distinct metacarpals, although the two meta- 

 tarsals are fused into a " cannon-bone," and the navicular and cuboid 

 are united ^. 



Schlosser ^, who places this genus in the Tragidid(^, refers ' Pro- 

 dremotherium and BachitJierium (pt. ii. p. 155) to the Cervidce ^ ; 

 but the resemblance between the dentition of Leptomery.v and Pro- 

 dremotherium appears too close to admit of their being classed in 

 distinct families ; and the reference of the former to the present 

 family therefore supports the view of Riitimeyer % who includes the

6 The Cervidce, together with the other Pecora, are regarded by this writer 

 as subfamilies of the Gelocidcs.
