106 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 10 



No. 214, with extreme posterior segments. There are 4 parapodia; all 

 setae have been broken off. Dorsal and ventral cirri are compara- 

 tively long. 

 No. 215, u^ith anal segments. This shov^^s a pair of short, though cirri- 

 form, ventral cirri and a pair of very long dorsal cirri. 



These parts agree so closely with similar ones from California col- 

 lections, earlier identified as E. biannulata Moore, that their identity 

 seems unquestionable. As the latter, it has been reported not only from 

 California but also from Lower California (Berkeley, 1939, p. 335) 

 and Socorro Island (Hartman, 1939, p. 13) ; also questionably from 

 Nanaimo, British Columbia (Berkeley, 1927, p. 407). E. longicirrata 

 has been reported from Elkhorn Slough, California (Berkeley, 1935, p. 

 771), and from central California (Hartman, 1938, p. 97). Differences 

 which have been noted between the two — variations in number of teeth 

 on maxillary plates II to IV and number of antennal articulations — are 

 believed now to have no specific significance. Berkeley (1935, p. 335) 

 separated E. biannulata from E. longicirrata, reserving the former for 

 those specimens in which anterior dorsal cirri have 3 articles, the basal 

 much the longer, and the latter for those in which the dorsal cirri are 

 very faintly and irregularly marked with from 7 to 9 articles. These dif- 

 ferences are difficult to apply to large collections, since they intergrade. 

 I am inclined to the view that there are no real differences between the 

 two, and thus refer E. biannulata to E. longicirrata. 



Another species, E. kobiensis Mcintosh, reported from southeast 

 Alaska (Moore, 1908, p. 345) and Pacific Grove, California (Tread- 

 well, 1914, p. 193), merits consideration here. The only difference which 

 I am able to find is that in this the branchiae are continued more caudal. 



E. harasii Audouin and M. Edwards, reported from British Colum- 

 bia (Berkeley, 1927, p. 407), may also be close to this; it differs from 

 E. longicirrata in having branchiae continued nearly to the posterior end. 



Color in life for an individual from Caledonia Bay (A 13-39) fol- 

 lows. The prostomial antennae are very pale gray with narrow bands of 

 red purple at the constrictions. The anterior end, dorsally, is dark vina- 

 ceous purple, the fourth segment pearly gray; at the sides, over the para- 

 podial base, there is a triangular spot of white with a tinge of lavender. 

 Parapodia are dull orange; parapodial dorsal cirri resemble the prosto- 

 mial antennae but are tipped with white. (Noted by Mr. Anker Peter- 

 sen.) 



Distribution. — E. longicirrata occurs in tropical west Atlantic waters, 

 including Bermuda (Webster, 1884), West Indies and Florida (Tread-
