The psoas magnus and iliacus are as in the Cat. 
The psoas parvus arises from the third, fourth, and fifth lumbar 
vertebree, and (as in the Civet) is inserted into the pelvis by a very 
strong tendon. 
The pyriformis, gemelli, quadratus lumborum, quadratus femoris, 
and the odturators are as in the Cat. 
A muscle which I did not notice in the Cat exists in the Civet: it 
arises in front of and below a very distinct antero-posterior ridge on 
the dorsum of the ilium. It is called gluteus quartus by Professor 
Macalister. 
Another muscle, which answers to my gluteus quartus in the Cat, 
is similarly conditioned to that of the Cat, both in Genetéta and 
Viverra. It also exists in Crocuta. This muscle is called gluteus 
quintus by Professor Macalister. 
The plantaris arises, in the Genet, only from the external condyle 
of the femur and the adjacent sesamoid bone, and is (as also in the 
Civet) only slightly united with the external head of the gastro- 
cnemius. It is inserted as usual. 
The gastrocnemius of the Genet has only three heads of origin— 
one from each femoral condyle and adjacent sesamoid, and one 
(mainly aponeurotic at its origin) from the fibula. There is no 
origin from the ligamentum patelle. The insertion is as usual. 
The soleus of the Civet is like that of the Cat. In the Genet it 
takes origin from the upper half of the fibula. Its insertion is as 
usual. It is wanting in Hyena striata and in Crocuta. 
The popliteus and tibialis anticus are both as in the Cat, and 
the same is the case with the Civet. In Crocuta it is double half- 
way down, the tendon of one part being inserted into the entocunei- 
forme, and that of the other into the rudimentary metatarsal of the 
hallux. 
The extensor longus digitorum of the Genet is like that of the 
Cat. In the Civet it gives origin to two main tendons, which sub- 
divide to supply the four outer digits, the details of the subdivision 
varying in different individuals. In Hyena striata the muscle 
divides into two bellies and gives off five tendons. In Crocuta it 
seems to be single, and is said to give off no tendon to the digitus 
minimus. 
The eatensor longus hallucis is absent in Crocuta and in the Cat. 
In the Civet it is slender, arises from the upper half of the margin 
of the fibula, and goes to the hallux only. In the Genet it is also 
slender and has a similar origin, but appears to end distally in an 
aponeurotic expansion extending dorsally on the hallux and index. 
The peroneus longus in the Civet and Genet is inserted into the 
fifth metatarsal as well as into the first metatarsal. In Crocuta 
and Hyena striata it is inserted into the fifth metatarsal only. 
The peroneus brevis and peroneus quiniti digiti are as in the 
Cat. The latter is wanting in Crocuta, but the former has two tendons. 
The extensor brevis digitorum of the Genet and Civet is much as 
in the Cat, but ends distally in an aponeurotie expansion rather 
than in quite distinct tendons. It goes to the four outer or to the four
