Family FELID^ (pt. i. p. 41). 



Genus MACH^RODUS (pt. i. p. 41). 



Machserodus cultridens (pt. i. p. 42). 



The upper canines are long and somewhat narrow; and, if the 

 following specimen be correctly referred, pm. 3 is absent, and the 

 mandible short, with, a comparatively small diastema. 



M. 3458. Cast of the right ramus of the mandible of a very old 

 individual, provisionally referred to this species. The 

 original is from the Forest-bed of Kessingland, Suffolk ; 

 and is described and figured by Backhouse and the present

 pi. X. Made in the Museum, 1886.

Maclimrodus leoninus, Koth and Wagner ^. 

 Meg anther eon aphanistus, Pomel *. 

 Drepa7iodon aphanistus, Cope ^. 



If the preceding specimen be rightly referred, the Pikermi and 

 Eppelsheim Machcerodus will be distinct from M. cultridens. The 

 upper canines are relatively broad, the diastema in the mandible of 

 the male is long, and pm. 3 present. Both this species and M. cul- 

 tridens are of large size. 



All the specimens from Pikermi and Eppelsheim entered in pt. i. 

 p. 43 belong to this form. 



Genus EUSMILUS, Gervais ^ 



Dentition : — I. -^, C. ~, Pm. ~, M. -. This genus agrees with Ma- 

 chcerodus in the general structure of the mandible and the large size 

 of the upper canines ; but differs in the excessive depth of the 

 descending portion of the mandibular symphysis, in the presence of
