464 MR. ST. GEORGE MIVART ON THE [June 24, 
Tliacus (figs. 8, 9, & 10, I). Of considerable size, this muscle 
arises from the internal surface of the antero-exterior margin of the 
pubic cartilage. It is inserted into the shaft of the femur from 
the proximal part of its anterior (extensor) surface down to the tibial 
condyle. 
Sartorius (figs. 8, 9,10, & 11, 8). A long slender muscle, which 
I did not distinguish in Menopoma, and which I propose thus to 
name, arises from the fascia attached to the antero-outer margin of 
the pelvis, into which fascia fibres of the external oblique are in- 
serted, so that this muscle appears like a continuation downwards 
of that, 7. e. of the external oblique. Passing downwards along the 
imer or tibial margin of the iliacus, it is inserted into the inner side 
of the upper part of the tibia just above and on the inner (or tibial) 
side of the insertion of the gracilis.

Deeper muscles of outer side of hinder part of trunk and anterior part of tail, 
and of the dorsal (extensor) side of right pelvic limb—the gluteus maximus, 
rectus femoris, and eatensor longus digitorum being cut and reflected.

Gluteus maximus (figs. 9 & 10, G.Mzx). This muscle is. very 
like the one so named by me in Menopoma, but it is rather more 
slender. It springs from the outside of the ilium, and, passing 
downwards, ends in an aponeurosis, which invests the knee anteriorly 
and passes to the upper part of the front of the tibia. 
The rectus femoris (figs. 9 & 10, R. F), very similar in shape
