    In the Ursicloo it is more often present than not. In the Mustelidas it is not only present but is quite a separate slip. Subclavitis.—This is a very small muscle rising from the inner end of the first rib and inserted into the spioular clavicle. We have only records of it in Viverra civeila (12) and Oeneita (16,18). It never seems to occur outside the ViverridsE, though from its insignificance it might easily be overlooked. The claviculo-scapu- laris, which is such a distinguishing feature of Hystricomoi’phine Ilodents (XLI.), is never found in Carnivora. Levator amjuli scajmlce and Serratus mac/nus.—These two muscles, as in Ilodents, form one continuous plane rising from a large number of the posterior tubercles of the cervical transverse processes and from a large number of the anterior ribs (see fig. 6, p. 382). The latter origins interdigitate with the scalenus longus and the external obhque. Although the muscle forms one sheet it is well to emphasize the distinction between the two parts, since the levator anguli scapulae is supplied by the cervical nerves and the serratus magnus by the posterior thoracic, or nerv'e of Bell. Meckel (XXXIX.) speaks of the levator anguli scapulae as a separate muscle coming from the atlas in the Dog, Badger, Otter, and Marten. In the Dog we have no other records of any origin from the atlas and regard Meckel’s specimen as a variation, but in the other three animals that which he describes as the levator anguli scapulae is undoubtedly the rhomboideus profundus. The insertion of the combined muscles is into the dorsal or vertebral part of the subscapular fossa of the scapula, the attachment being much more strongly marked anteriorly than posteriorly.
