In view of the relations to the Mm. intercostales and their nerve supply, as a rule they were considered to be independent muscles formed by the separation of one part of the muscle bundles of the Mm. intercostales internus (Eisler) which, instead of inserting into adjacent ribs, had extended further to other ribs. A case of abnormal type by SATOH was found, however, in which this muscle appeared to be a separation from the M. intercostalis intermedius (Eisler) and will be presented here. This condition was found in 1 case (number 777, male) during a study of the bodies of 10 Japanese. This case showed the additional abnormality of having large communicating branches between adjacent intercostal nerves. The muscle described here as being the M. subcostalis was found bilaterally in the same intercostal space with identical findings on each side. This was a band-like muscle which arose from the upper edge of the third rib and crossed over the second rib to the lower edge of the first rib, where it became tendinous and terminated apparently by union and continuation into the origin of the M. intercostalis intermedius (Eisler). Inspection of the relation between this muscle and the underlying M. intercostalis (in the outer layer) showed that the M. intercostalis internus was absent in the first intercostal space so that the M. intercostalis intermedius was in direct contact with this muscle, but no fusion was seen between these two muscles except at the site of insertion. The M. intercostalis was found to be exposed beneath the pleura even in the second intercostal space, and the M. intercostalis internus and intermedius could not be separated so that the M. inter-, Acta medica Nagasakiensia. 1973, 17(1-4), p.1-3},
