Xh( lemispherical, stout 2.9 mm. in diameter at the base, almosl 



completely 1 with cirrus ts; the small dorsa] pole is papillose, as in E. chamberlaini. 



The cirri are NXXV — L, i<> 18, 1 <> mm. to is mm. long; the first segment is v< 

 short, iboul twice as broad as long, the third nearly or quite as long as the proximal 



diameter, the fourth from two to two and one half times as long as the proximal diameter, 

 the ' enth the longest, nearlj or quite three times as long as the proximal diameter; 



ving very gradually decrease in length so ili.it the antepenultimate is from one third 

 : half again as long as broad; the cirri are nol especially slender; they become mode- 



ompressed laterally in the distal half; the longer earlier segments have a slight central 

 triction, and the shorter distal have the proximal dorsal angle cut away so that the distal 

 il 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. chamberlaini; the distal inter- 

 tl 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. 



1' is 7 mm. long with 15 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 P n and the outer 

 segments have slightly prominent distal angles and slightly spinous distal edges. 



1' is 10 mm. long with 19 segments, resembling P, but tapering slightly less rapidly 

 and with the outer segments relatively longer. 



is trom 4.5 mm. to 5.5 mm. long with 10 — [3 segments, smaller than P.,, though 

 similar to it. 



1' is 6.5 mm. long with 14 segmei 



Th( pinnules are extremely slender, 8 mm. long with 1 7 segments. 



The arms are about 75 mm. long. 



Dorometra A. II. ('huk. 



Kej to the Species of the Genus Dorometra. 



a 1' resembling P, in size and in number of segments, or slightly smaller 



b 1 cirr: nents relatively short, the longest about two and one half times 



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 1 P, with 18 — 20 segments, 6 mm. to 7 mm. long, slender and Bagellate; 



.5 mm. long with 12 segment imilar bul slightly smaller, 2.7 mm.
