md the third are sul eing quite so long as broad; the fourth to the eighth 



nr ninth have slightl) prominent dist. il i especially dorsally. The cirri are rather stout, of 



Japanese E. variegatus. 

 The five arms 75 mm. long; the brachials are unornamènted, and their «listal

to the tip, th< tal border of the segments sharply, though narrowly, carinate; P, is 4.5 mm. 



, similar to Pi ; Pg is 11 mm. long with 17 segments, very slender like 

 . the succeeding pinnules, though very stiff; the first two segments 



slightly broader than long, the third and fourth halfagain as 

 long as broad, the following gradually increasing in length aml 

 becomin- distally three or fonr times as Ion- as broad; the distal 

 edges of the third and following segments are; produced and spinous ; 

 the pinnule resembles the lower pinnules in certain of the more 

 slender species of Colobometra ; 1', is similar to P a , 11 mm. long 

 with 1 7 segments; I'i, is similar to 1' . S mm. long with 18 segments ; 

 1' is s mm. long with is segments. proportionately more slender 

 than 1', and with much shorter segments, which become as long 

 as broad on the third and twice as long as broad proximally on 

 the tenth or eleventh; P c and \\ are 7.5 mm. long with iS 

 segments, and resemble the preceding pinnules; the distal pinnules 

 are 12 mm. long with 20 — 24 segments which bevond the fifth 

 are twice, and distally are three times, as long as broad, with 

 very finely spinous distal ends. 



The colour is white, the perisome of the pinnules purple; 



on either side of the middorsal line of the arms there is a broad 



yellow brown line: these lines are always parallel, so that there is between them a uniform 



white middorsal streak of about their own width; beyond the arm bases they become faint and 



imexa zigzag course, shortly after which they disappear. 



The characteristic features of this species are the stout cirri composed of very short 

 segments, and the very slender proximal pinnules; in the first of these it agrees with /:. varie- 

 gatus of Japan.
