eral parts of the fourth to the seventh cervical vertebras, 

 and in part by fibres from the first dorsal vertebras. An- 

 other origin is tendinous from the midline of the neck 

 upon muscular fibres of the other side, and not from the 

 processes of the cervical vertebrae. This portion com- 

 bines with the other origin and is inserted by a broad 

 aponeurosis on the occiput on a line above the insertion of 

 the Trachelo Mastoid, extending forward obliquely to the 

 middle line Of the top of the skull. The fibrous insertion 

 gets shorter and shorter, and on the medial line of .the 

 head it becomes muscular. 



M. Splenius Capitus Inferior (?). 



Just below the preceding we find another large, flat 

 muscle which may be a part of the Splenius Capitis, or a 

 new muscle, Splenius Capitis Inferior. 



It arises from the median dorsal process of the axis, 

 and is inserted directly below by a muscular and some- 

 what tendinous insertion into the occiput, from the median 

 line to the neighborhood of the insertion of the Trachelo- 

 mastoid, and a little behind it. Both muscles are large, 

 thin and well marked. 



M. Laryngoglossus Superior. 



The Laryngo-glossus Superior forms the back part of 

 the muscular mass just in advance of the hyoid bone 



(base hyal, epi hyal) and also of the larynx. It extends 

 from the back of the base of the tongue to the larynx. 

 Its origin is intimately blended with that of the Laryngo- 

 glossus Inferior. The length of the muscle is about 20"

Laryngo-glossus Inferior. 

 This muscle lies inside of the Laryngo-glossus Supe-
