68 CARNIVORA. 
b. From the Pleistocene of Buenos Ayres. 
37682. The distal extremity of the left humerus of a feline Car- — 
nivore about the size of a Leopard, exhibiting a large ent 
e-picondylar foramen. This bone belonged to an adult 
animal, and is far too small for Macherodus neogeus. 
Bravard Collection. Purchased, 1854. 
ce. From the Pleistocene of the Narbada Valley, India. 
15924. Distal extremity of the right femur of a species of the size 
of a large Tiger. Presented by C. Fraser, Esq. 
15922. Distal extremity of the left femur, of rather smaller size 
than the last specimen ; collected at the village of Naogaon 
in 1839. No history. 
d. From the Pleistocene of England. 
M. 1625. Portion of the humerus (apparently) of a large feline ; 
| from the Forest-bed of Kessingland, Norfolk. This speci- 
men is noticed by Newton in the Mem. Geol. Surv. 
England and Wales, ‘‘ Vertebrata of Forest-bed Series of 
Norfolk and Suffolk,” p. 23 (1882). 
Presented by Miss L. Martineau, 1884. 
Family HY A NIDA. 
In many respects the typical genus is more intimately allied to 
Cams (notably in the structure of the feet and the absence of an 
entepicondylar foramen to the humerus) than to the preceding 
family ; and as some of the Viverride are extremely close to the 
Felide, the former family is very frequently placed next to the 
latter. The relationship of Cynodictis to the Vwerride is, how- 
ever, so extremely intimate that it seems imperative to place the 
Canoids and Viverroids in juxtaposition. The dentition of some of 
the most specialized species of Hycna is moreover extremely feline, 
while some of the more generalized forms (Lepihyena) are very like 
those of some of the primitive felines, so that there are strong indi- 
cations of affinity between the two families. On the other hand, the 
more generalized species of Hywna (H. macrostoma) exhibit very 
strongly marked affinities to the Canoids, while the genus Jctathe- 
rium closely connects other species (H. sivalensis) with the Viver- 
roids ; so that the impossibility of exhibiting the full affinities of a 
group by any lineal system of classification is very strongly exem- 
plified.
