The Pelvis. 



The absolutely longest pelvis (measured from the most preaxial 

 part of the ilium to the tuberosity of the ischium) I fouud was 

 30"'4 (Lion). In Crocuta it was 12""45. The greatest lengths I 

 found in the Fiverridae were 12"-7 {Arctictis) and U"-7 {Fiverra 

 civet to). 



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 Felidce was 20*9, and the smallest in the Fiverridce 17'4 

 {Genetta). 



The greatest breadth of the ilium I found to be in Fiverra 

 civetta 3 "'O, in Genetta l"-3, Paradoxurus 1"*0, in Galidictis 0""9, 

 in Galidia 0"'9, in Arctictis 2'"4, in Cryptoprocta 2 ""O, in Her- 

 pestes 0""8, in Eupleres \"'7, in Crossarchus l"'3, mSuricata \."'3, 

 in Proteles 4"'2, in Hycena striata 7 "'9, in Crocuta 10 "'4, and inFelis 

 catus 1"*8. 



The ilium has its ventral preaxial angle enormously produced in 

 the Hyanince, its preaxial margin nearly straight, and its tuberosities 

 greatly everted. In Crocuta 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, Fiverra, Crossarchus, 

 and especially in Surieaia. 



The Femur. 



The absolutely longest femora I found were 35"*5 (Tiger) and 

 31"*3 (Lion). The largest Viverrine femur was 14""7 (Arctictis). 

 It is 22"-8 in Crocuta. 



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 

 (Suricuta). The shortest are 19"3 (Viverra civetta) and 20" 1 (Fi- 

 verricula). In Proteles and Crocuta it is 265 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 Paradoxurus, 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 Arctictis 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 Hyana the small
