The anterior cirri are very short, less than half as long as the second pair; the rami have 0 and 9 joints, respectively.

The rest of the cirri are long, composed of long joints, which bear four pairs of spines on the anterior and three pairs of smaller ones on the posterior sides (fig. 1, b, sixth joint of the exopodite of the third cirrus), though the development of spines varies on different parts of the same cirrus. The caudal appendage I tig. 1, d) is very small, perhaps an eighth as long as the last ramus, composed of four joints, the first one long (perhaps really composed of two joints), the last bearing a terminal tuft of long spines. Type, no. 32417 L'. S. National Museum, from Albalross station 4353, off Point Loma Light-House, 639 fathoms, seated on a glassy spine or spicule. The shape of the scutal and of the inframedian plate is not like any of the known species, S. insigne being apparently the nearest. A young individual in the same group, shown in the figure, is interesting as showing that the young are more normally calcified than the adult stage, the calcification after an early age proceeding only al(jng certain lines indicating the longer axes of the valves. This young individual has a capitulum mm. long. The valves of this specimen resemble those of S. itisignc Hoek more than tlo those of the adult Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
