    Sterno-mastoicl.—This muscle rises from the anterior part of the sternum and is inserted into the occipital curved line, the para- mastoid, and sometimes the paroccipital process; it may be more or less fused with the cleido-mastoid at its insertion. Among the Viverridm Meckel (XXXIX.) has noticed that the sterno-mastoid consists of two layers, superficial and deep, in Herpestes (22), and we have confirmed his observation in H. nepalensis (^^3) and griseus (24). In Oenetta vulgaris (18) the same arrangement exists, but it was not noticed in Paradoxurus typus (19, 20) or Tig. 4. C£f^ ,JiY0/O.^ GE/^.NY GlOi ?iTE-GLO££ DlG/iSTRlC (C UT.) HYO. GIOS 7HY.NY .

In many cases the sterno-mastoid is fused with its fellow of the opposite side near it s origin in the posterior part of the neck; this seems to occur most often among the Hy/enidie, Canidae, Ursida?, Procyon- idse, and Mustelidse, though it does not always happen in these families—for instance, the two sterno-mastoids were fused in the [10]
