The Pelvis. 
The absolutely longest pelvis (measured from the most preaxial 
part of the ilium to the tuberosity of the ischium) I found was 
30'-4 (Lion). In Crocuta it was 12'"45. The greatest lengths I 
found in the Viverride were 12'”*7 (Aretictis) and 11'*7 (Viverra 
civetta). 
Compared with the length of the spinal column (atlas to sacrum), 
taken at 100, the greatest proportional length of the pelvis was 
27-1 (Hemigalidia), and the smallest 14°4 (Crocuta). The smallest 
in the Felide was 20:9, and the smallest in the Viverride 17:4 
(Genetta). 
The greatest breadth of the ilium I found to be in Viverra 
civetta 3''-0, in Genetta 1''*3, Paradoxurus 1'':0, in Galidictis 0'''9, 
in Galidia 0'°9, in Arctictis 2:4, in Cryptoprocta 2':0, in Her- 
pestes 0''°8, in Eupleres 1''"7, in Crossarchus 1''*3, in Suricata 1""3, 
in Proteles 4'':2, in Hyena striata 7""9, in Crocuta 10"*4, and in Felis 
eatus 1"°8. 
The ilium has its ventral preaxial angle enormously produced in 
the Hyenina, its preaxial margin nearly straight, and its tuberosities 
greatly everted. In Crocuéa these conditions especially obtain: the 
ilium is more concave externally ; and the process for the rectus 
(preaxial to the acetabulum) is very strongly developed. In Proteles 
these characters exist in a less pronounced degree. 
There may be two prominences (each like an ilio-pectineal promi- 
nence)—one just preaxiad to the acetabulum, and the other placed 
a little more ventrally on the pelvic brim. These may both be 
found (at least sometimes) in Cryptoprocta, Viverra, Crossarchus, 
and especially in Suricata. 
The Femur. 
The absolutely longest femora I found were 35''5 (Tiger) and 
31"°3 (Lion). The largest Viverrine femur was 14'"7 (dretictis). 
It is 22'°8 in Orocuta. 
Compared with the spine at 100, the longest femur is 31°3 (Felis), 
27°9 being the minimum feline proportion. The longest Viverrine 
proportions are 28°2 (Cryptoprocta), 27:5 (Genetta), and 26:7 
(Suricata). The shortest are 19-3 (Viverra civetta) and 20°1 (Vi- 
verricula). In Proteles and Crocuta it is 26°5 and 26°4. 
The femur is always a little longer than the humerus. 
In the Civet and Genet the bone is relatively shorter than in the 
Cat, and the lesser trochanter is relatively somewhat smaller. 
In Paradozurus, Nandinia, Cynogale, and Hemigalea it is much 
flattened behind between the trochanters; and thus the lesser tro- 
chanter is thrown almost under the head of the femur instead of 
being behind (postaxial to) it. In dretietis this flattening is at its 
maximum, the lesser trochanter is very small, the trochanteric fossa is 
shallow, and the great trochanter is relatively smaller than in other 
species. In Crossarchus and Suricata the femur becomes thicker in 
proportion to its length than in most species. In Hyena the small
