It arises from the transverse processes of the coccyx just 

 in advance of the Ischio Coccygeus, and is inserted on the 

 upper edge of the pelvis, on the posterior upper edge of 

 the base of the circular ridge, which encloses and forms 

 the acetabulum. 



Tlie Rectus Capitis Articus Major, and the Rectus Capi- 

 tis Articus Minor, the Scalenus, the Complex and the an- 

 terior part of the Trapezius have all been correctly 

 described by Mivart. The same is true also of the Tra- 

 chelo-mastoid. 



Constrictors of the oesophagus are well developed. 

 Two of these are well marked. 



M. Constrictor Superior. 



This constrictor is the largest of all. It is a broad, flat 

 muscle, which arises from the whole length of the hyal 

 bones above the thyrohyal. The muscle is inserted into a 

 median raphe along the front of the neck. Intimately 

 connected with this Constrictor Superior is a flat muscle, 

 which from its position and character, I have identified as 

 a Stylo-pharyngeal. It arises by a broad origin above 

 the Superior Constrictor, i. e., between this muscle and 

 the neck, and is inserted into the median raphe blending 

 with the same constrictor. The Superior Constrictor may 

 thus be regarded as representing both the Superior and 

 Inferior of Anthropotomy. Another constrictor of the 

 oesophageal region arises from the thyroid cartilage, just 

 above a Crico thyoid, and is inserted into the median 

 tendinous raphe of the back of the cesophagus. It is 

 smaller than the Superior which has been already men- 

 tioned. 



Still lower down, below this constrictor, we have a 

 small muscle which arises from the same tendinous raphe 

 of the oesophagus, and extends downward under the pos-
