Excerpt: . have a more or less raised transverse girdle, sometimes beaded. Laterally, the brachials often have small, buttress-like projections, which sometimes ramify into the interbrachial network, in which the base of the arms entirely disappears, as if ending in branching roots. The arms are very strong at their bases, tapering gradually to great lengths. They are observed in several specimens for a distance of 300 mm. without reaching the ends; calculating from the taper of the ultimate divisions, and comparing this with the detached distal portions seen occasionally among the specimens, it is clear that the arms were often at least 15 to 20 inches long. They bifurcate at increasing intervals (longest at the inside of the dichotom) three or four times, and frequently one of the last pair once again, thus giving from 80 to 120 ultimate arms. The brachials from the tertibrachs up are exceedingly short and wide throughout; their extreme shortness is a very conspicuous feature, probably characteristic of the genus. The arms are highly rounded dorsally, and have a broad, shallow, ventral furrow, which becomes more deeply notched distally; the cross-section is more or less crescentic; from the truncated horns of the crescent proceed relatively large, closely abutting pinnulars. The form and relative proportions of these plates in the different divisions of an arm are shown by the series of figures on Plate IV. There is so little difference between the anal interradius and the regular areas that it is scarcely noticeable; one more plate in the second or third, and in the fourth anal range is all that differentiates them. The interbrachial pavement.--The most interesting morphological feature of this species is the peculiar interbrachial network, or.<
