trochanter is largely developed, and there is a large process above the 

 outer condyle. In Crocuta there is no marked process of the kind, 

 and the lesser trochanter is but of moderate size. In Proteles, which 

 has a long and slender femur, the small trochanter is little developed, 

 but there is a process above the outer condyle. 



The Tibia and Fibula. 



The absolutely longest tibia is 30" '2 (Tiger). The greatest pro- 

 portional lengths to the spine at 100 are 3 1-8 {Felis) and 29" I {Gali- 

 dictis). The least proportion in Felis is 24' 7. Its least proportion 

 in the Viverridee is lil*3 {Viverricula') ; and its greatest after Gali- 

 dictis is 28"6 and 2S"4 {Genetta and Hemigalidia). I have found 

 it equal to the femur in length in Nandlnia, Herpestes, Crossarchus, 

 and almost so in Proteles. I have found it longer than the femur 

 in the Wild Cat and Domestic Cats (but not the large Cats), the 

 Civet, Genet, Bdeogale, Cynictis, Siiricata, Galidictis, Galidia, and 

 Eupleres. I have found it shorter than the femur in the larger 

 Cats and in Viverricula, Paradoxurus, Hemigalea, Arctictis Cyno- 

 gale, Cryptopacta, and the Hycenince. The tibia is always longer 

 than the radius, except in the HycEnina, where it is shorter. 



The tibia of Hemigalea is remarkable for the very great projection 

 mesiad of the internal malleolus, which allows the pes to be more 

 obliquely articulated, so that the plantar surface may be directed 

 more inwards than in most jEluroids. In Paradoxurus the same 

 condition exists, though in a less marked degree. 



In Eupleres the fibula is exceptionally strong amongst the Viver- 

 ridcE, and the process at its distal end is very strongly developed 

 outwards and postaxially. 



The Pes. 



The greatest length of the pes (measured from the front of the 

 distal end of the tibia to the end of the fourth digit) is 30"-7 (Felis) ; 

 the least is 16""2 (Crocuta), In the Viverridce I have found it range 

 from 25"'3 (Galidictis and Suricata) to 16"'3 (Viverra civetta). The 

 length of the pes is always greater than that of the manus, except 

 in Crocuta. They are exceptionally equal in Arctictis, where, the 

 manus being as 100, the pes is 1197. 



The greatest relative length of the fourth metatarsal is 15'1 

 (Felis), and the least is 8'0 (Cynogale). The length of the fourth 

 metatarsal corresponds with the third metacarpal. 



The metatarsus is proportionally inost elongate in the Felidce. 

 It is shortest and stoutest in the Viverridce, especially in such forms 

 as Arctictis, Cynogale, and Hemigalea. 



There is no hallux, save a rudimentary metatarsal, in the Felidte, 

 Hycenidcs, Cynictis, Bdeogale, and Suricata. Though present in 

 all the other genera, its length, compared with that of the index 

 of the pes, may vary considerably. 



The hallux (when developed) always extends half down the meta- 

 tarsal of the index. It may only extend about half down the meta-
