defined tendon of origin ( 614). Upon the muscle are also written tlie names M. occipito- 

 scapularis, hiatus trapezii, and Gl. tymphatica. 



Cermco-auricularis ( 615). This muscle of the ear is shown at the dorsimeson between 

 the ear and the M. supra cervico -cutaneus ; its name is omitted. 



Clavo-deltoideus ( 637). See also acromio-deltoideus. 



Claw-trapezius ( 615). See also acromio-trapezius. 



Dermo-humeralis ( G29). Most of this dermal muscle was removed with the skin ; the 

 name is written across the brachial end which passes between the MM. triceps and latissi- 

 mus to be attached to the latter and the bicipital arch. 



Latissimus ( 635). This is more commonly called latissimm dorsi. Its caudal por- 

 tion is covered by the skin ; its dorso- cephalic angle is overlapped by the spino-trapezius, 

 but exposed in Fig. 67. 



Levator claviculce ( 627). The scapular end is seen to emerge from entad of the claw- 

 trapezius, to partly overlap the acromio-trapezius and to be inserted upon the imperfectly 

 defined metacromion rather than upon the clavicle, as might be supposed from the name. 



Occipito-scapularis ( 617). This is fully shown in Fig. 67. Here, its lateral border 

 appears at the dorsal end of the hiatus trapezii which has been enlarged so as to show the 

 position of the muscle. 



Spino-deltoideus ( 674). See also the acromio-deltoideus. 



Spino-trapezius ( 611). See the acromio-trapezius. 



Sterno-mastoideus ( 622). Part of this shows darkly between the skin of the neck and 

 the claw-trapezius. It is more fully shown in Fig. 67 and 72. 



Supra-cermco-cutaneus ( 615). Most of this cervical dermal muscle was lifted with 

 the skin, and only its reflected dorsal end is shown. 



Teres ( 680). This appears in the interval between the spino-trapezius, spino-deltoideus, 

 latissimus and triceps. By inadvertence, the name is written with the addition of the 

 qualifying adjective major ; since the muscle more often called teres minor is here desig- 

 nated as micostalis, there seems to be no need of a compound term for the muscle in question. 



Triceps. The name is written across the two largest portions of the muscle commonly 

 known as triceps in man. The M. is upon the scapular head, here called meditriceps 

 ( 682), and most of the rest of the name is upon the part here called ectotriceps ( 684) ; 

 the surface of the latter presents a superficial furrow. 



Other Parts. Gl. (glandula lymphatica). A somewhat large lymphatic gland embed- 

 ded in the fat which occupies the hiatus trapezii. 



Gl. (glandula) parotis The parotid salivary gland (Fig. 87). The caudal border of 

 this usually pale gland is exposed by slightly cephaloducting the occipito-presternal edge 

 of skin. 



Gl. (glandula) sulmaxillaris The submaxillary salivary gland (Fig. 87). This appears 

 a little ventrad of the Gl. parotis, and is usually of a deeper color. 



Hiatus trapezii ( 613). This is an elongated lozenge shaped interval between the 

 cephalic margin of the M. acromio-trapezius and the caudal and dorso caudal margins 

 respectively of the MM. claw-trapezius and levator claviculce. In reality, the very open 

 angle formed by the intersection of these two borders is near the middle of the length of 

 the hiatus, but in the preparation the margins of the MM. claw-trapezius and acromio- 

 trapezius have been artificially separated a little farther dorsad. 



V. (vend) jugularisThe jugular vein (Fig. 101). This is exposed between the M. 

 claw-trapezius and the margin of the skin, where it obliquely crosses the M. stcrno-mastoi- 

 deus. 



609. Exposure. It is usually more convenient to expose the
