scription given by Duvernoy. It is seen upon turning 

 back the Mylohyoideus or Myloglossus, and the Annulus 

 Inferior. It runs along above the Geuio-glossus and is 

 inserted into the hyoid bone. 



M. Genio-glossus. 



The Genio-glossus proper, or, as it might be known in 

 comparison with the Genio-glossus Posticus, the Genio- 

 glossus Anticus, has an extensive origin along the inner 

 edge of the ramus of the lower jaw, from the Genio-glossus 

 Posticus to within a short distance of the symphysis of 

 the jaw. The muscular anterior part of the origin ends 

 at a point 35 mm . distance from the tip of the snout. The 

 muscle also has a firm attachment to the thick membrane 

 which forms the floor of the mouth, and is attached firmly 

 to a large muscle that lies underneath it and in the inter- 

 val between the tongue and the lower maxillary bone, 

 from a little in advance of the condyle, to the end of the 

 jaw. The Genio-glossus is inserted into the median raphe 

 of the posterior part of the tongue, below the broad in- 

 sertion of the Genio-glossus Posticus Interus. The gen- 

 eral shape of the Genio-glossus is that of a very obtuse 

 angled triangle, whose larger angle is at a point of its 

 insertion into the inner side of the lower maxillae, under 



the origin of what I have named a Genio-glossus Posticus 

 i 



Interus, about 10 ram . in advance of the coronoid process 

 of the lower jaw. 



Mm. Splenius Capitis et Splenius Colli (?). 



The muscle which I identify as a Splenius Capitis is in 

 two parts, one superficial to the other, but so distinct are 

 they, that we might call them Splenius Capitis Inferior 

 and Superior. The most superficial arises from the lat-
