several cliAergent clusters of capillary setye, a group, sometimes of six to 

 eight, loug, stout, spine-like, dark brown, acute and barbed setae, having 

 several short recurved hooks on each edge of the flattened tips, near the 

 end. The ventral rami of the parapodia are prominent and bear three, or 

 more, stout, elongated, brown set;i», with shar^), somewhat recurved tips, 

 which are covered aloug the convex side with slender, sharp spinules; 

 at the end of the straight shaft, and separated • by a naked space from 

 the spinulated portion, there is a strong, sharp, divergent spine. Length 

 of a medium-sized specimen, 32'"'"; breadth, exclusive of seta', 13""" j 

 length of palpi, 7"^'™. 



Common on nnuldy bottoms in the Bay of Fundy and Gulf of Main<', 

 in 50 to 150 fathoms. Collected first in 1804, 1S05, and 1808, by tlie 

 writer and Professor S. I, Smith, and subseciuently by the IT. S. Fish 

 Commission, in many localities. 



It differs from L. fiUcornis, with which it was formerly identified by 

 me, not only in having a much smaller median antenna, but also in the 

 character of the sette, especially those of the ventral fascicle. Whether 

 the Gulf of St. Lawrence specimens, recorded by M'Intosh as L. fili- 

 cornls, belong to this species, is uncertain. 



Euiioa spinulosa, sp. nov. 



Body large, oblong, rather narroAv, of nearly equal breadth through 

 the greater j)art of its length. Head dark, deeply l:)ilobed in front, the 

 sides rounded ; each lobe terminates in an anterior, acute, white point. 

 Eyes large, lateral, the anterior farther apart than the posterior. ^Median 

 antenna rather small, about twice as long as the liead, tapering- to a 

 slender point; lateral antennae smaller and about half as long as median ; 

 palpi moderate, smooth, nuich stouter and longer than the antenn;ie; 

 tentacular and dorsal ciiri long, slender, cx)vered with numerous slender 

 papillae. Scales large, broad, rounded-oblong, the posterior part being- 

 produced and broadly rounded, the surface covered with minute, rounded 

 grains and toward the border with very small, elongated, tapering, acute 

 spinules; outer edge fringed vntli numerous small, slender papill;e. 

 Setie yellow, very abundant, forming large, dense tufts. Those of the 

 upper parapodia are in part as long as those of the lower, and much 

 stouter; the upper ones are shortest, unequal, stout, ciii-ved, spine-like, 

 acute, finely and closely transversely serrulate throughout most of their 

 length, only a very small tip being smooth ; below these there is a grouj) 

 of longer and smoother s])ine-Iik(^ seta^, the serrulation less distinct and 

 not extending so far toward the base nor so near to the lip. The ventral 

 parapodia have very numerous set*, less than half as thick as the u]>])cr 

 ones, but the longest about equal to or somewhat exceeding- those of the 

 upper fascicle; tbey are all of one general form, decreasing much in 

 length toward the lower side; the shaft is loug and smooth, the distal 

 portion enlarged, someAvhat curved, closely s])inulated, ending- in a short, 

 smooth, slightly incurved, acute tip. Length (a few posterior segments
