am also inclined to doubt such a condition, and it seems 

 highly probable to me that the Hypoglossus is in reality 

 a muscle, which I describe as M. JMyloglossus, not follow- 

 ing in that respect, Duvernoy, who calls it a Mylohyoid. 



M. Stylohyoideus. 

 A Stylohyoideus muscle is largely developed. It arises 

 just behind the base of the tube of the meatus auditorius 

 externus, by means of a tendon, and s[)reads out forming 

 a flat muscle on the median line of the neck. Along the 

 median line there is a slight groove and raphe. In its 

 anterior portion, the muscle is simply joined, with its 

 fellow of the opposite side. Farther back it is joined to 

 the hyoid bone itself. 



M. Stylothyroideus. 

 The Stylothyroideus is a small, delicate muscle, which 

 arises from the stylohyal bone and runs down back of 

 and parallel with the stylohyal and epihyal, and is in- 

 serted into the th3'rohyal on its posterior and upper bor- 

 der. This insertion is tendinous. The origin from the 

 stylohyal is muscular. The length of the muscle is 17""". 



M. Hyothyroideus. 



A broad flat hyothyroid muscle, of quadrangular shape 

 arises from the posterior edge of the thyrohyal and the 

 epihyal, and is inserted into the thyrohyal along the pro- 

 jection extending obliquely from the process, above the 

 insertion of the Stylothyroid muscle. It is from 8-10""". 

 long, and 6"™. broad. 



M. Genio-hyoideus. 

 The Genio-hyoid is well marked and answers the de-
