Annelida of the Bermudas. 601 



being twice as long as broad. Upper branchiae are preserved only on 

 the posterior third of the body ; the most anterior seen are cordate- 

 lanceolate, one-third longer than broad, with blunt tips; farther back 

 they become narrower lanceolate. Caudal cirri large, dark colored, 

 oblong-ovate, obtuse, 4 times as long as broad. Setae are long and 

 very slender, the blades rather long, straight, very acute. 



The color in formalin is reddish brown (in life probably green) ; 

 the branchial appendages and caudal cirri are more deeply pigmented 

 than other parts, and nearh^ opaque ; a transverse fusiform lighter 

 spot exists between the segments, bounded by narrow, curved, whitish 

 lines ; there is a dark spot at the dort^al base of the parapodia, sur- 

 rounded by a pale zone. 



Length, as preserved, about 14™™ ; diameter 1™™, in life much 

 longer. 



Eulalia megalops, sp. nov. 



A long and slender, dark green species with very large eyes. 



Body wider in the middle, tapering gradually to both ends. Head 

 ovate, obtuse in front, longer than broad. Eyes very large, black ; 

 four frontal antenna long, slender, whitish ; odd tentacle similar in 

 size ; 4 pairs of long, slender, tapered tentacular cirri, the dorsal 

 pairs longer, in life six times as long as head. Branchial lobes of 

 l^arapodia falcate, long, narrow, acute, curved upward, \^ to 2 times 

 as long as breadth of body. 



Color, in life, mostly dark olive-green ; branchiae light green ; 

 anterior segments with a whitish transverse marginal line and a pale 

 median patch. Length, in life, 90™™ ; breadth, 1.5™™.

Syllis Saviguy. (Including TyposylUs and Ehlcrsia*) 



The genus Syllis is here taken to include those species having 

 minutely bidentate tips to the terminal blades of the compound setae, 

 as well as those in which the tips are acute. In some species both 

 forms occur on the same individual and in many cases the bidenta- 

 tion is so slight as to be visible only under a high power objective 

 (e. g. No. 6, Zeiss or Leitz, or 1 inch American), so that it seems 

 useless to make this a generic character. JEusyllis Malmgren was 

 separated mainly on this account from Syllis, but the type species, 

 E. Jiloinstrandi M., also has the dorsal cirri nearly smooth or with-
