470 PROF. ST,-GEOR6E MIVART ON THE ^ELUROIDEA. [Juiie 6, 



Proteles the scapula is not unlike that of Viverra ; the metacromion 

 is rather larger and more pointed than in Hycena. In Proteles, 

 Hycena, and Crocuta the acromion is shorter than in the Felidce or 

 Viverridce, except sometimes in Eupleres. 



The angle formed by the axillary margin with the spine of the 

 scapula varies from about 20° {Surieata, Galidictis, Proteles) to 35° 

 (Lion and Tiger). The average angle is a little above 25°. 



The Clavicle. 



The clavicle is always very rudimentary or absent ; nevertheless in 

 Genetta I found to be about 1"'6. 



The Humerus. 



The absolutely longest humerus is 3 1"* 5 (Tiger), the largest 

 Viverrine humerus is 14"'0 (Arctictis). The greatest proportion of 

 the humerus to the spine at 100 is 28'5 (sometimes in Felis), the 

 shortest is 18' 1 (Eupleres). The shortest feline proportion is 23'4 ; 

 the greatest Viverrine proportion is 25'0 (Arctictis). Crocuta is 

 220, and Proteles 24"8. The Civet's humerus, compared with that 

 of the Cat, is stouter, with the great tuberosity relatively more pro- 

 minent, and the fossa outside it much deeper and larger. The 

 supinator ridge is also stronger, while the bony bridge enclosing the 

 foramen for the median nerve is more slender. There is some- 

 times an olecranal foramen. The humerus of the Genet is more like 

 that of the Cat. There is always a condyloid foramen, except in 

 Cynogale, the Galidictinee, and the Hyanidce. In Paradoxurus 

 the internal condyle may be much prolonged. In Arctictis the 

 humerus is much broadened out distally, with a rather small condy- 

 loid canal and a strong supinator prominence ; there is no marked 

 pit outside the great tuberosity. In Cryptoprocta exactly reversed 

 conditions obtain, as the condyloid canal is very large in that genus 

 (at its maximum), and there is a very marked pit outside the great 

 tuberosity, as also in Herpestes, Crossarchus, and Hycena. In Her- 

 pestes the humerus is much curved. In Crossarchus the deltoid 

 surface is very prominent, and the development of the supinator 

 ridge and the projection of the internal condyle are at their maxi- 

 mum. The deltoid surface is even more prominent in Surieata. 

 In Hemigulea the humerus is a good deal bowed, the great tubero- 

 sity and the supinator ridge are little developed, but the internal 

 condyle is very prominent. In Viverricula, on the contrary, the 

 internal condyle projects so slightly that it is almost effaced. la 

 the HycenidcE the internal condyle is also relatively little developed, 

 the deltoid surface is prominent, there is an olecranal perforation, 

 and the pit outside the great trochanter may be wide and shallow as 

 in HycBna, or wide and deep as in Proteles. 



The Radius and Ulna. 



The absolutely longest radius is 26"'0 (Tiger) ; its greatest pro- 

 portional lengths to the spine at 100 are 27'4 (sometimes in Felis) and
