    The rectus capitis anticus minor is pyramidal in shape, and arises from the transverse processes of both the axis and atlas, as in Tarsius'. It is inserted into the exoccipital just within the mastoidal region of the periotic (fig. 1, R. c. a. min.). The longus colli arises from the fronts of the bodies of the four anterior dorsal vertebrae, and is attached to the bodies and transverse processes of all the cervical vertebrae, three distinct tendons going to the bodies of the atlas, axis, and third cervical vertebra (fig. 1, L. c.).

Muscles of the Trunk.—The two *rhomboid muscles are repre- sented by a single one, which is largely developed. It arises Irom the spinous processes, from the fifth cervical to the fifth dorsal in- clusive, and is inserted into the spinal border of the scapula from its anterior end to near its posterior extremity. The *levator anguli scapula: is a very strong muscle, and arises from the transverse processes of all the cervical vertebrae except the first. It is inserted as usual. Meckel2 3 says, “Dans les Loris il se rend settlement a l atlas. If such is the case in Loris gracilis, -it is far from being so in Nyctice- bus. The levator posticus scapula of Burmeister1 was absent. 1 Burmeistcr, op. cit. p. 39, t. 5. fig. 14 o. - Anat. Comp. vol. vi. p. 236. 3 Op. cit. p. 47, t. 4. fig. 1. no. 4. [4]
