lateral edges almost meet, being separated only by a narrowly V-shaped cleft running to the 
edge of the inner edge of the synarthrial joint face; though the dorsal surface of the segment 
is well rounded, the distance from the central canal to the median part of the dorsal edge is 
not so oreat as the distance from the central canal to the inner angle; counting the entire 
median leno-th of the joint face the broadest portion is found to be scarcely more than one 
third of the distance from the dorsal edge to the inner angle; the ossicle is sharply "wall- 
sided" from its widest point inward; the axillaries are low, rhombic, with the lateral angles 
truncated so that lateral edges are about as long as the lateral edges of the IBr^ twice as 
broad as long; there is an obscure well rounded median carination; the distal angle is produced, 
but broad; the dorsal surface is rather strongly convex; the lower portions of the axillaries 
are strongly produced inward so that, as in the case of the IBrj, the inner sides are reduced 
almost to apices which nearly meet the similar inner ends of the other axillaries; from this 
central point the inner face of the axillaries slopes away almost horizontally so that the inner 
faces of the axillaries, together with the division series, form the platform upon which the 
visceral mass rests; the sides of the inner half of the axillaries are sharply "wall-sided"; the 
IlBr series are similar to the IBr series, but rapidly decrease in dorsoventral width; they are 
sharply flattened laterally for somewhat more than their inner half; the first two brachials are 
flattened laterally for their entire inner side, and the third and fourth are flattened on the 
inner portion of the inner side. 
The nineteen arms are 145 mm. long. All of the lIBr .series are 2. 
Pj is slender and evenly tapering, 9 mm. to 10 mm. long, composed of from twenty-six 
to thirty-one segments all of which are much broader than long. P., is similar, but very slightly 
stouter, of the same length or very slightly longer, composed of twenty-hve segments of which 
the outermost are about as long as broad. P., is i i mm. long, composed of twenty-two 
segments; in general it resembles P„, but the segments in the di.stal half are about as long- 
as broad. P^ is 1 1 mm. long with twenty segments which become as long as broad on the 
fifth or sixth, and slightly longer than broad terminally. P. is 9 mm. long with fifteen segments, 
most of which are about as lone as broad. 1^ is 8 mm. lone with fourteen segments, and 
P,, is 7 mm. long with thirteen segments. The distal pinnules are slender, 10 mm. long with 
twenty segments. On the genital pinnules the third-seventh segments are very slightly, almost 
imperceptibly, broadened. 
The colour, in alcohol, is brownish white, the centrodorsal and division series brownish grey. 
Another specimen, similar to the one just described but smaller (Cat. X" 35707 U.S. 
Xat. Mus.), was dredged by the "Albatross" oft" southern Luzon, Philippine Islands, in 243 
Metres (Stat. 5110); it also has nineteen arms; the fourth-tenth segments of the genital pinnules 
are somewhat expanded, considerably more so than in the preceding.
