of Delfortrie, is said to present a dental structure not unlike that of 

 Buncelurus, but I liave not had the opportunity of reading his diag- 

 nosis. . 



BUN^LTJRUS LAGOPHAGUS, Cope, loc. cit, 1873, p. 8. 



Eepresented by a portion of a mandibular ramus, which carries the 

 sectorial and tubercular teeth, and another, more perfect, from the right 

 side, which contains the two last premolars as well as the sectorial and 

 tubercular teeth. Thus the number of premolars is uncertain. Those 

 preserved are narrowly acuminate ; the basal lobes of No. 3 quite small. 

 The middle lobe of the sectorial is considerably higher than the anterior, 

 and the heel, though short, is well developed. Tuberculai? small ; crown 

 longitudinally extended. ^ 



This feline was about the size of a half-grown cat.

General character of dentition as in Machcerodus^ but the mandibular 

 teeth are : C, 1 ; P. m., 3 ; M., 1, a premolar tooth being added. Sec- 

 ond premolar three-lobed; carnassial tooth with short cutting-heel; 

 tubercular none. Superior canine much compressed, denticulate, not 

 grooved.

DAPTOPHILUS SQUALIDENS, CopC, loc. cU. 



Established on a specimen in which the permanent sectorial of the 

 lower jaw is protruded, but the temporary sectorial not yet displaced 

 by the permanent last premolar. Second premolar with strong, sub- 

 equal anterior and posterior basal lobes and two-rooted. Enamel 

 smooth. 



Sectorial with two posterior lobes, the lower prominent. Eamus 

 decurved at symphysis. Superior canine in shape, like a tooth of a 

 shark of the genus Oxyrliina ; flat within, slightly convex without ; the 

 front cutting-edge turned inward at the basis ; both edges denticulate. 

 The fang of the inferior canine penetrates beyond a point below the 

 first premolar.
