The centrodorsal is low hemispherical, stout 2.9 mm. in diameter at the base, almost 
completely covered with cirrus sockets; the small dorsal pole is papillose, as in E. chainberlaini. 
The cirri are XXXV — L, 16 — 18, 16 mm. to 18 mm. long-, the iirst segment is very 
short, the second about twice as broad as long, the third nearly or quite as long as the pro.ximal 
diameter, the fourth from two to two and one half times as long as the pro.ximal diameter, 
the fifth-seventh the longest, nearly or quite three times as long as the proximal diameter; 
the following very gradually decrease in length so that the antepenultimate is from one third 
to one half again as long as broad; the cirri are not especially slender; they become mode- 
rately compressed laterally in the distal half; the longer earlier segments have a slight central 
constriction, and the .shorter distal have the proximal dorsal angle cut away so that the distal 
dorsal angle of the preceding appears prominent; all the segments have prominently overlapping 
distal ends; the cirri do not taper distally 
The division series and arm bases resemble those of E. chamber laini; the distal inter- 
syzygial interval is three oblique muscular articulations. 
P, is 5.5 mm. long, composed of 1 1 or 12 segments of which the first is not quite as 
long as broad, the second is about as long as broad, the third is half again as long as broad, 
and the remainder are about twice as long as broad. The pinnule is slightly stiffened, and 
tapers evenly from the base to the tip. 
P„ is 7 mm. long with 1 5 segments of which the first is twice as broad as long, the 
second is nearly as long as broad, the third is half again as long as broad, and the remainder 
are about twice as long as broad. The pinnule is proportionately stouter than Pj, and the outer 
segments have slightly prominent distal angles and slightly spinous distal edges. 
P.; is 10 mm. long with 19 segments, resembling P, but tapering slightly less rapidly 
and with the outer segments relatively longer. 
P, is from 4.5 mm. to 5.5 mm. long with 10 — 13 segments, smaller than P,,, though 
similar to it. 
P. is 6.5 mm. long with 14 segments. 
The distal pinnules are e.xtremely slender, 8 mm. long with 17 segments. 
The arms are about 75 mm. long.

a' Pj resembling Pj in size and in number of segments, or slightly smaller 
b' cirrus segments relatively short, the longest about two and one half times 
as long as broad, the penultimate and antepenultimate not more than one 
third again as long as broad; arms from 30 mm. to 45 mm. in length 
c' Pg with 18 — 20 segments, 6 mm. to 7 mm. long, slender and flagellate; 
Pj 3.5 mm. long with 12 segments; P., similar but slightly smaller, 2.7 mm.
