62 MESSRS. MURIE AND MIVART ON THE 
thick transverse process of the first sacral vertebra, also from the fascia connected with 
the upper (posterior) margin of the ilium. 
It gives origin to tendons which are inserted upon the caudal transverse processes, 
which it connects together, the tendons arising from the posterior transverse process of 
one vertebra and going to the anterior transverse process of the vertebra next but one 
behind that from the transverse process of which it springs. 
These semiunited series of muscular bellies and tendons are seen in position in the 
Thick-tailed Galago, Pls. V. & VL. figs. 19 & 25, It.cd, and a segment of the tail with 
two muscles of the one side hooked out in Pl. VI. fig. 26, [¢.ed. 
These can hardly be said to be present in the short-tailed genera. We could not 
define them in N. tardigradus. 
5. Muscles of the Pelvic Limb. 
a. Pelvic Regions (Dorsal and Ventral aspect). 
Guvrevs Maximus, or Ecto-gluteus of Owen'.—In Lemur this is a very large and 
powerful muscle*, with an extensive origin and also an extensive insertion. Its origin 
is partly aponeurotic and partly muscular. It arises by aponeurosis from the anterior 
superior (posterior superior of Man) angle of the ilium, from the lumbar fascia (at its 
posterior part), and from the spines of the sacral vertebre. It arises by muscular fibres 
from the inferior anterior (anterior superior of Man) spines of the ilium and from the 
transverse processes of the first three caudal vertebre. The part which arises by 
muscle from the inferior anterior spine of the ilium is that which is described as the 
tensor fascize latee by Burmeister in Za/sivs, and is connected only by aponeurosis with 
the part which arises from the anterior superior angle of that bone—this aponeurosis 
covering over the gluteus medius lying beneath. This muscle is inserted (gliding over 
the outside of the peroneal trochanter) into the third trochanter, and into the posterior 
surface of the femur side by side with the adductor magnus, and very closely connected 
with it. No fibres are inserted into the aponeurosis of the thigh. 
There is a certain distinctness between the part arising from the pelvis and that 
coming from the tail; the long supracaudal muscles passing above the origin of the 
caudal part, and beneath that of the sacral portion. 
In L. wanthomystax and L. nigrifrons the insertion extended right down to the ex- 
ternal condyle. 
In Galago the aponeurotic interval is less perceptible, and there is a strong tendon 
running along the inferior margin of the part inserted into the third trochanter. See 
‘ In the Trans. Zool. Soc. vol. v. pp. 15, 65, Prof. Owen has proposed the terms “ ecto-,” ‘ meso-,” and 
“ento-,” for the gluteal muscles respectively, as indicating their relative position ;.for in Mammals their pro- 
portional volume is not the same as in Man.
