| It is located at the front end of the trunk, limited anteriorly by the lower border of the neck, posteriorly by the axillae and the interaxillary region, and on each side by the arm. |
| Occasionally the flower emerges midway between two nodes and is internodal rather than interaxillary in position. |
| The plates, together with the radial frame work, and the interradial and interaxillary areas, make up the body of the criuoid, which is plainly pentagonal in outline. |
| Lymphograms indicate that the axillo-inguinal and interaxillary collaterals are collectors that go in the same direction and that form the shortest connection between two node groups. |
| The interaxillary pieces are all very small, two of them being wedged down, one upon the top of the other, in the narrow space between the first and second secondary radial pieces. |
