496 PROF. ST.-GEORGE MIVART ON THE ZLUROIDEA. [June 6, 
tendinosus. In the Hyena it descends at least to the middle of the 
leg!; Dr. Watson says to the os calcis in Crocuta. 
The semitendinosus of the Genet (as also the Civet) has a delicate 
head, which arises from the third caudal vertebra at the hinder end 
of the caudal origin of the gluteus maximus, with which it is con- 
terminous. This head joins the other part of the semitendinosus 
about one third down the femur, and becomes slightly connected with 
the tenuissimus. It is inserted as in the Cat, but the upper tendon 
of its insertion is not so distinct. This muscle has no caudal origin 
in Crocuta. 
The semimembranosus is in the Genet quite asin the Cat, save that 
its two parts are more separate—separate for nearly the whole length 
of the muscle. The part from the ramus of the ischium goes to the 
femur; that from its tuberosity to the tibia. In Crocuta it is 
quite inseparable from the adductor magnus. 
Agitator caude—This muscle, which I did not observe in the Cat, 
arises in the Civet from the first and second caudal vertebrz, and is 
inserted into the back of the femur. In the Genet its origin blends 
with the hinder end of the caudal origin of the gluteus maximus. 
It is crossed by the sciatic nerve and goes to the lower third of the 
femur (rather behind its outer margin), and extends down almost to 
the external condyle. 
In the Genet and Civet there is a special sphincter of the scent- 
glands. 
The sartorius is double in the Genet and, sometimes at least, in 
the Civet?. One part arises from above and behind the anterior 
superior spine of the ilium and goes to the patella; the other part 
springs from below the first part, and is lost in the fascia on the 
inner side of the knee. It is also double in Crocuta. 
The pectineus in the Genet is as in the Cat. It is large and 
double at its insertion in the Civet*. In Crocuta it goes from the 
ilio-pectineal line to the middle of the linea aspera. 
The adductor mass of the Genet is substantially similar to that 
of the Cat, though, as in the Civet, it may be divided into three parts. 
One of these, the adductor primus, is attached to the semimem- 
branosus*, Another, the adductor secundus, is very wide and short 
and is separable into two layers. The third part, or adductor 
longus, is attached halfway down the femur. In Crocuta there are two 
adductor muscles, which both arise from the pubic arch, and which 
are inserted, respectively, one into the internal condyle and internal 
tuberosity of femur, and the other into the whole length of the 
linea aspera and into the internal branch of its lower bifurcation. 
The quadriceps extensor of the Genet is as in the Cat, save that 
the crureus takes origin along the whole length of the femur, up 
to the neck of that bone. The crureus is not differentiated in Cro- 
cuta, and the vaséi are hardly separable.
