longer and more slender, with very acute, straight tips and, as stated 

 above, project laterally as very prominent fringes. 



No color remains. 



The only specimen comes from station 4,420, off San Nicholas Island, 

 32-33 fathoms, fine gray sand. 



This species is evidently closely related to'E. maculata Horst from 

 Timor, but lacks serrated, ringent dorsal setae. Compared with 

 E. dumosa, it appears remarkably broad and depressed, besides differing 

 in many technical characters. 



AMPHINOMIDiE. 

 Chloeia pinnata sp. nov. PI. XV, figs. 1-6. 



A very pretty, small and slender species of a slightly depressed, 

 fusiform shape, tapering most toward the caudal end. The type is 

 26 mm. long, 6.5 mm. wide at XI, where it is 5.5 mm. deep, and has a 

 spread of setae of 12 mm.; segments 26. Other specimens vary in 

 length from 7 to 30 mm. and have from 17 to 28 segments. 



Prostomium coalesced with peristomium, its broadly truncate 

 anterior border produced laterally round the peristomial parapodia; 

 ventrally it appears as a tumid elliptical pad divided by a median 

 longitudinal cleft and reaching the mouth; dorsally somewhat 

 T-shaped, the broad anterior end extending laterally, while posteriorly 

 it is contracted between the parapodia of somites I and II. Caruncle 

 arises from the prostomium and reaches to the anterior or occasionally 

 to the posterior border of IV, but is entirely free from these segments, 

 over which it passes like a flowing plume. Two longitudinal furrows 

 divide it into a compressed crest with accordion-plaited sides and 

 smaller basal ridge also divided by transverse furrows into twelve or 

 thirteen deep crenulations, each marked, like the crest folds, with a 

 small brown spot. Eyes two pairs, black, equally conspicuous, but 

 the anterior slightly the larger, situated at sides of anterior end of 

 caruncle, the anterior slightly in advance, the posterior slightly behind 

 the anterior border. Median tentacle arising from a low, smooth 

 elevation coalesced with anterior end of caruncle, the style moderately 

 slender, tapered, smooth, suberect, about one-fourth longer than the 

 caruncle, but fragile and seldom complete. Paired tentacles sessile, 

 in contact between anterior eyes, similar in form to median tentacle 

 and about one-half as long. 



Peristomium and its parapodia completely coalesced with prosto- 

 mium, not appearing as a distinct segment. Somite II well-differen- 

 tiated, divided ventrally by the mouth and forming the rugous lateral
