Tue APPENDICULAR SKELETON. 
The Pectoral Limb. 
The proportion borne by the entire pectoral limb (humerus, 
radius, and manus) to the spine—the length from the front of the 
atlas to the hinder end of the sacrum being taken as 100—is never 
more than 77°9 (as sometimes in Felis), or less than 42°3 (Vi- 
verricula). 
The greatest proportion amongst the Viverride is 66°4 (Suricata) ; 
the shortest found by me in the Felide was 52°9 (I. eyra). 
The Scapula. 
- The extreme length of the scapula compared with of the spine 
(estimated as before) is as 21:0 to 100, as sometimes in Felis. In 
that genus I have found 18°6 to be the minimum proportion. In 
the Viverride it varies from 11°9 (Nandinia) to 18°9 (Cynictis). 
In Proteles it is 19°7, and in Crocuta 20°6. 
The Civets have the scapula much more in the shape of a paral- 
lelogram than have the Cats, the preaxial border not being so 
convex. The metacromion is not so much developed ; and the pro- 
portion borne by the infraspinatus fossa to the supraspinatus fossa 
is greater, as also in the Genets, in which the scapula is otherwise 
more feline. Fussa and Puradoxurus are intermediate between 
Genetta and Viverra in the form of the scapula; but the convexity 
of the preaxial border is generally situate nearer to the glenoid 
surface than it is in the Genet. 
In COynogale the scapula is much like that of the Civet, but the 
prominence of its preaxial margin is more rectangular in outline and 
less rounded. 
Arctictis resembles Paradoxurus; but its infraspinatus fossa is 
still larger relatively ; the spine is but little prominent, and the 
metacromion quite rudimentary. In Herpestes the metacromion is 
well developed. There is sometimes a prominence for the teres 
major; and the proportional size of the infraspinatus fossa may not 
be greater than in the Cat. In Crossarchus there is sometimes so 
sharp a prominence from the glenoid end of the convexity of the 
preaxial border as to form a deep suprascapular notch. The meta- 
cromion is well developed, as also in Suricata (where its apex issharply 
bent backwards); the outer surface of the scapula is in this genus 
singularly concave. In Galidia, the convexity of part of the pre- 
axial margin may be very great ; but here, as seems to be generally 
the case, there is much individual variation in the form of the 
scapula. In Eupleres the metacromion is well developed, but the 
acromion may be very short. In Cryptoprocta the scapula is very 
like that of some Cats; the infraspinatus fossa is not so large rela- 
tively as in Genetta; the metacromion is well developed. In Hyena 
the preaxial margin is rounded; the metacromion is very minute 
and placed quite at the end of the spine; the supraspinatus fossa is 
smaller relatively than in the Cats, or than in the Viverride gene- 
rally; both it and the infraspinatus fossa are very concave. In
