tiguous to it behind, and the ilio-peroneal in front. It is inserted 
into the postero-external side of the great trochanter, immediately in 
front of the insertion of part of the femoro-caudal, and conterminous 
with the hinder border of the gluteus primus. 
Gluteus tertius (fig. 17, D*®). A small and delicate muscle, which 
I thus distinguish, arises from a small portion of the lowest part of 
the posterior margin of the ilium, beneath the origin of the gluteus 
secundus. It is inserted into the outer side of the great trochanter, 
just below the insertion of the last-named muscle, and conterminous 
with the upper end of the insertion of the gluteus primus. 
Pectineus? A very small and delicate muscle lies hidden between 
the gluteus tertius and the insertion of the iliacus. It arises, just 
behind the brim of the pelvis, from the lowest part of the outer side 
of the ilium, below the origin of the gluteus primus. It is inserted 
into the outer side of the upper part of the femur, beneath the 
gluteus tertius, of which, indeed, it may be but an accessory portion.

Adductor (figs. 19, 23, & 24, 4). This thick muscle arises from 
the pelvis, at and near the ischiatic symphysis. Passing down, it is 
inserted into rather the outside of the shaft of the femur, below the 
insertion of the femoro-caudal and below and outside the inser- 
tions of the obturators. It is obscurely divided into a longer and 
more slender posterior part, and a thicker, shorter, more anterior 
portion.
