Publisher's Synopsis
Excerpt from The Journal of the College of Science, 1912, Vol. 29: Art. 2
Ambulacral appendages minute, Without end-plates, but their shape is more like that of a bluntly ending pedicel than of a conical papilla. The smaller ones among them are no larger than mm, while the larger ones are as much as mm. In length. They can, especially in the larger specimens, be recognized only by the openings or canals seen to enter them from inside. Ambulacral appendages are most numerous on each side of the two lateral ambulacra, which run along the some what thickened edge between the dorsum and the ventrum. They are especially numerous in the posterior parts or in those parts which project on each side of the vertical pygal furrow, where, when foreign particles have been cleared off, they project, giving a fvillous appearance. The largest appendages are along these two ambulacra. On the two dorsal and the median ventral ambulacra, small appendages are found along the two sides of each ambulacrum. These are minute, sparse, and can be seen only when the skin has been mounted as a whole and examined under the microscope.
