Dissections of Galago crassicaudatus, being deep views of the head, neck, and lower 
(posterior) limb: all nearly natural size. 
Fig. 16. Segment of the skull, the neck, and the thorax of the Thick-tailed Galago. 
prepared to show the deep ventral muscles of the neck and the supracostal 
slip. The sternal cartilages have been cut through on the left side, and the 
costal parts pushed outwards. 
R.a.ma. Rectus capitis anticus major, in 
position on the right side, partially 
severed and pulled out on the left. 
R.a.mi. Rectus capitis anticus minor. 
Rl. Rectus lateralis. 
L.c'. Longus colli, first portion (dragged 
outwards). 
L.c?. Longus colli, second division(dragged 
outwards). 
Ms. Mastoidal inflation of periotic. 
L.c’. Longus colli, third or deep part. 
S.mg. Serratus magnus. 
Sca'. Scalenus (the long thoracic division 
piercing the serratus). 
Sca®. Scalenus (short portion). 
S.c. Supracostal. 
R.ab. Rectus abdominis. 
Ste. Sternum. 
Fig. 17. Portion of the inferior palatine surface of skull, with part of the mandible. 
The latter loosened at its articulation and twisted inwards, to show the 
pterygoid muscles. 
Ept. External pterygoid, cut through, part of the insertion being seen on the 
uptumed coronoid portion of the mandible. J.pt. Internal pterygoid, crossed by 
the inferior dental nerve and artery. 
M. The right mandible. 
Ms. Mastoidal eminence. 
artery passing into inferior dental foramen. 
I.dn. Inferior dental nerve and 
Fig. 18. A somewhat similar view of the under surface of portion of the skull, also on 
the left side, but the position reversed. The tongue, not entire, has been 
pushed to one side, allowing a moiety of the palate to be seen. 
Posteriorly 
some of the stylo-pharyngeal and deep muscles of the neck are traced. The 
mandible is inclined outwards, to display the pterygoids. 
Ipt. Internal pterygoid. 
E.pt. External pterygoid. 
R.a.ma. Rectus anticus and part of longus 
colli. 
Rl. Rectus lateralis. 
M. Mandible. 
To, 'Tongue. 
S.c.ph. Portion of the superior constric- 
tor of the pharynx. 
Sy.g. Stylo-glossus. 
Sy.h. Stylo-hyoid. 
Sy.ph. Stylo-pharyngeus. 
Ms. Mastoidal bulla.
