The *splenius is exceedingly large, and there is no splenius colli, 
thus confirming Meckel’s' observations. 
The *compleaus is also very strong, extending down to the spi- 
nous processes of the three first dorsal vertebrae. We did not find 
the division spoken of by Meckel? as existing in Loris. 
The *cervicalis ascendens is, as usual, continued from the sacro- 
lumbaris, and is inserted into the transverse processes of the two 
first dorsal and the last cervical vertebree. 
The *¢ransversalis cervicis is continued upwards from the longis- 
simus dorsi, but takes fresh origin from the three first ribs. It is 
inserted into the outer ends of the transverse processes of the cervi- 
cal vertebree, from the seventh to the second inclusive. 
Meckel® differs from Burdach* as to what goes to form the cer- 
vicalis ascendens. Our observations agree with the latter author. 
The *levator clavicule, which is not noticed in the memoir on 
the genus Stenops, we find to be a long but slender muscle. It 
arises from the transverse process of the atlas, and is inserted into 
the outer end of the clavicle, and not into the acromion process. At 
its insertion, the fibres are in close union with those of a portion of 
the deltoid. 
This muscle was noticed by Kuhl’ in A¢eles in the year 1820, 
and appears to be the levator anticus scapulee of Burmeister®; it is 
the acromio-trachélien of Cuvier’, the clavio-trachélien of Church’, 
and spoken of as an undetermined muscle by Meckel’. 
The omo-hyoid has no median tendon, but is a strong muscle. It 
arises from the os hyoides, and is inserted into the anterior margin 
of the scapula at the inner end of its middle third. 
Muscles of the upper Extremity—The pectoralis major arises 
from the whole length of the sternum and the sterno-clavicular arti- 
culation. It has not the clavicular fasciculus noticed by Profs. 8. 
Van der Kolk and Vrolik in their memoir, and which has also been 
found strongly marked in Cheiromys"*. This muscle hardly seems 
to merit the epithet “trés-faible” given by Meckel" to it in the 
Loris. 
The coraco-brachialis consists of a long and a short portion. The 
former arises by a strong tendon from the coracoid process, and 
is inserted into the anterior surface and inner border of the hume- 
rus, down to the middle of the upper surface of the condyle. The 
latter or short portion, which is muscular at its origin, also arises 
from the eoracoid process, just internal to the tendon of the long
