334 MESSRS. MURIE AND MIVART ON THE [Apr. 11, 
clear as to this essential nature of the ¢ransversalis cervicis in Man ; 
and Burdach corrects Meckel on this point as regards the Apes. 
Of course it cannot be considered as the Jiventer cervicis, as this is 
always on the inside of the complexus. 
The transversalis cervicis is but the continuation of the longis- 
simus dorsi, and is very wide and conspicuous. It is inserted into 
the five lowest cervical vertebrae by muscle, which has superimposed 
conspicuous tendons, one to each transverse process. This is the 
cervicalis ascendens of Meckel *. 
The cervicalis ascendens is wanting, as there is no evident continu- 
ation of the sacro-lumbalis into the neck, except perhaps a few fibres 
to the seventh cervical vertebra. 
The rectus capitis posticus major is a large and powerful muscle, 
arising from the spine of the axis, its whole outer surface, and with 
an insertion into the occiput. 
The rectus capitis anticus minor, as usual, extends from the neural 
laminz of the atlas to the occiput, beneath the last. 
The origin of the ob/iquus capitis superior is the transverse pro- 
cess of the atlas. Its insertion is into the occiput, between the su- 
perior and inferior curved lines. 
The odliquus capitis inferior is very large. Its origin is from the 
neural lamina and base of the spinous process of the axis, and it is 
inserted into the transverse process of the atlas. 
These last four muscles are exceedingly well developed, and they 
together form a prominent inverted fleshy pyramid. 
The levator clavicule is strong; it arises from the transverse pro- 
cess of the atlas, and is inserted into the fascia covering the teres 
minor, passing over the neck of the scapula. Meckel does not notice 
this muscle in the Hyraa. 
Muscles of the Back and Abdomen. 
Trapezius.—This muscle is very extensive, arising along the me- 
dian line of the back, from the occiput as far as the middle of the 
dorsal region, overlapping the latissimus dorsi. It is inserted into 
the scapula—the anterior part of the muscle upon the spine towards 
its acromial end, the posterior part of the muscle below (behind) the 
spine. Some fibres of the anterior portion of the muscle are involved 
with the platysma myoides, somewhat in the manner described by 
Meckel +. 
The rhomboideus major has origin from the spines of the 6th, 7th, 
8th, 9th, and 10th dorsal vertebree, with an insertion into the poste- 
rior angle of the scapula. 
The rhomboideus minor is represented by a small delicate muscle, 
arising from the spine of the sixth dorsal vertebra, and being inserted, 
superficially to the last, into the cartilaginous portion of the scapula. 
These muscles are probably subject to some variation, as Meckelt 
describes three muscles in the place of these two, and in addition 
our next muscle also.
