Although this sulcus occupies a dorsal position in the 

 Ohevrotain, Musk-Deer, and others of the Ungulates, such 

 behaviour is unknown elsewhere in the Carnivora. 



The precrucial sulcus limiting the so-called " Ursine 

 lozenge " is well developed (fig. 148). 



As also in Ictonyx, the lateral sulcus does not extend far 

 in the caudal direction. 0. C. 1325 Nrf.
