Diagnostic feature*. The cirri arc rjhort and stout, with none of the component 

 segments longer than broad; l' a and P 2 are elongated and stiffened, but slender like 

 the pinnules succeeding and ool enlarged, with the third and fourth segments half again 

 a> long as broad and the distal segmeute three or four times as long as broad; these 

 pinnules are of the aame length as the succeeding pinnules and are composed of 11 

 segments. 



The short, stout, ahort-segmentod cirri distinguish this species from all the others 

 in the genua except E. variegatus and E pinnatus. From E. variegatus it is distin- 

 guished by the alendemess of P, and Pg, which are composed of longer segments, and 

 from E. pinnatus it is distmgushed by the fad that these pinnules are of the same 

 length as those succeeding and are composed of only 11 segments. 



Description. As described by (iisl6n the centrodorsal is 1.8 mm. in diameter. 



The cirri are XX, 20-21, from 9 to 10 mm. long. The first two segments are 

 broader than long, the third is about as long as broad, and the fifth-seventh are one- 

 quarter again as long as broad. The segments are smooth, slightly constricted cen- 

 trally, and rather stout. The height of the opposing spine is two-thirds the width of 

 the penultimate segment. The terminal claw is curved, and is as long as the penulti- 

 mate Begment. 



The radiate are \MI>le as narrow smooth bands about 5 times as broad as long. 

 The syzygial pair formed by the elements of the IBr series is as long as broad with 

 rather pronounced ventrolateral ledges. 



The live arms are 4(i 45 nun. long and are smooth. The first brachial is 1.4 mm. 

 in w idtli. 



IV i- 3.S linn, long and is composed of nine segments. The first segment tapers 

 strongly distallv. and the second segment is the broadest. The first three or five 



tents have a distallv directed crest of which the height is equal to one-third the 

 width of the segments. P, is 4 mm. long, with 10 segments and is similar to P c . 

 P m is ") mm. long, with 11 a gments, of which the third is half again as long as broad 

 and the distal are two or two and one-half times as long as broad with a somewhat 

 spiny distal edge. P| is 5 mm. long, with 11 segments. P b is 5 mm. long with 12 



onts, P is 5 mm. long with 1 1 segments of which the distal have a small spiny 

 wreath. The distal pinnules are 4.5 mm. long, with 16 or 17 segments which are 

 three times as long as broad and of which the last three bear dorsal hooks. Each seg- 

 ment bears four pair- of large sacculL 



As preserved in alcohol the arm- are dorsally brown with white transverse spots, 

 and the pinnulars are whitish with the saeculi darker. The cirri are white. 



Notes.- Dr. Gialen said that at first he had some doubt whether this specimen 

 represented a distinct species or was merely a fully grown individual of the type he
