﻿MURIE ON THE THREE-BANDED ARMADILLO.

of Ouvier^s 'Legons'S of the abnormal position of the sartorius in the M (Bmdt/pus), 

 which Macalister ' afterwards decides in favour of the great German anatomist. In 

 Tol^pentes, a small abnormally attached sartorius, I believe, does exist, although in my 

 notes of the dissection I appear partially to have confounded it with the tensor vaginse 

 femoris. 



. There is, however, a very apparent though small pectineus, spoTven of by Hyrtl in the 

 Chlamy dophorus and Galton in the 6-banded Armadillo— in this case springing from the 

 pubic rod in front of the ilio-pectineal eminence, and passing towards the root of the inner 

 trochanter. 



Adductores.— Instead of there being only a single adductor muscle, as interpreted by 

 Galton in Basypm e-cinctm and depicted by Cuvier and himself, I find there are at least 

 three, if not a fourth division, in Tolypeutes ; and a many-headed adductor obtains in 

 Chlamydophorus, That which I take to be an adductor magnus, as in Man, converges 

 in two planes, and is relatively large and strong. It has origin from the whole of the 

 front of the upward (horizontal) and descending pubic rami, and from the ischial surface 

 around the posterior border of the obturator foramen. By its insertion, the posterior 

 and somewhat flattened superficies of the femoral shaft, from third trochanter to botli 

 outer and inner condyles, is occupied. The muscle answering to adductor longus is 

 smaller than the preceding. It springs in close relation witli it above and on the upper 

 (outer) end of the horizontal ramus of the pubis, and inferiorly it is fixed to the posterior 

 surface of the lesser (tibial) trochanter. The adductor brevis at the pelvis comes from 

 the outside of adductor longus, and it goes to the inner edge of the femoral shaft below 

 the tibial trochanter as far as midway between it and i\\Q inner condyle. There i^, 

 moreover, an additional slip of fleshy fibres lying beneath the two last-mentioned muscles. 

 This has an origin betwixt them, and is inserted upon the sharp inner edge of the lesser 

 trochanter. 



I defer notice of the obturatores until mentioning the inner pelvic and subcaudal 

 muscles. 



The tibialis anticus has a broad origin from the whole of the outer surface of the tibia 

 (excepting just above the malleolus), also from the interosseous membrane. Its tendon 

 is inserted upon the entocuneiform, but not to the metatarsal. In D. sexcinctua Galton ' 

 mentions it as likewise possessing a considerable fibular origin ; but he, Huxley *, and 

 Macalister ^ agree as to a single inferior tendon ; so does Hyrtl ^ in the Chlamydophormt 

 " ossi naviculari insertum." 



An extensor longus hallucis is wanting. It is present', though small, in the last-men- 

 tioned animal and in the six-banded Armadillo. In the first an external malleolar, 

 and in the second a fibular origin is assigned it.
