92 The Alligator and Its Allies 
is very thin, but increases in thickness more and 
more as it passes cephalad. A short anterior and 
a long posterior portion may be distinguished. 
The former extends from the inner side of the right 
to that of the left half of the lower jaw, without 
a median aponeurosis. The hinder half of this 
muscle is united by a pair of aponeuroses to the 
lower jaw, on one hand (the smaller part), and to 
a fascia, on the other hand (the far larger part), that 
separates several of the neck muscles. The smaller 
part begins immediately behind the pterygoid on 
the inner side of the halves of the lower jaw but 
ends on the outer side of the two halves of the jaw. 
Latus Colli (Latissimus colli accessorius). Lies 
underneath the preceding. Its muscle bundles lie 
between the collo-capitis muscle and the bodies of 
the first three cervical vertebra, and form a broad 
band that extends from the hyoid bone to the 
backwardly directed cervical ribs of the first and 
second pairs. 
Coraco-ceratoideus (Omo-hyoideus, Coraco-hy- 
oideus). A long, narrow, and moderately thick 
muscle which takes its origin from the upper border 
of the coracoid, where the latter touches the scapula. 
It extends forward near the cesophagus and at- 
taches itself to about the middle of the backwardly 
turned border of the horn of the hyoid of that side. 
Episterno-ceratoideus (Niederzicher des Zungen- 
beins, or Brustbeinzungenbeinmuskel, Sterno-hy- 
oideus). A flat and fairly broad muscle which
