There are trom Stat. 315 two small, indifferently preserved specimens, that for the 

 structure as well as for the arrangement <»f their ventral bristles cannot 1»- identified with /:'. 

 complanata 1'all. The length of tin- largest specimen is about lomni., whereas the number of 

 its segments amounts to nearly 40; the smaller one is incomplete. Of course it is not without 

 doubt whether these worms an- full-grown; however in young specimens of E. complanata of 

 the same length the bristles have already the appearance, that is characteristic to this species. 



The caruncle is short, flexuous, in the smallest specimen extending to the fourth (fifth 

 Kinberg segment, whereas in the largest specimen it only reaches the third one; it is remarkable, 

 that in the description Kinberg says "segmentum quintum attingens", whereas in the figure it 

 only attains the third (fourth Kinberg) segment. The unpaired antenna is small; the paired ones 

 are much larger and coarser and consist of a basal part and a distal one. 



The neuropodial fascicle contains short bifurcated bristles, having the longest limb either 

 smooth (PI. IX. lig. 21) or conspicuously serrated (PI. IX. tig. 22); moreover this limb usually 

 is not incurved, but either nearly straight or even somewhat bent backward. Besides these this 

 iele shows several (not one or two as in E. complanata) slender subfurcated setae (PI. IX. 

 fig. 23), the shortest limb of which is only a merc spur, whereas the longest limb is densely 

 serrated along its interior margin. In the notopodial fascicle the harpoon-shaped bristles are 

 faintly developed, showing only somc small denticulations in their distal part; the subfurcated 

 bristles much resemble those of the neuropodium, but the longest limb is more coarsely serrated. 

 The setae of our worms show a great resemblance to those of /;". chilensis, figured by Kinberg 

 on Plate XII, figs. 9 Gu, /', / and S; however I suggest, that a mistake lias crept into this 

 delineation and that s" should be 11 and also represents another kind of ventral bristle, for I 

 never met with a dorsal bristle of this shape in the Eurjtlnh'-s\>cc\cs. 



The specimen of Stat. 47 is an incomplete worm, that lacks the posterior segments ; it 



is a female with eggs, about 10 mm. in length. The caruncle is very faintly developed, extending 



only over the first segment; its neuropodial fascicle contains a great number of elongated bristles, 



with a denticulated distal extremity, but even wanting the spur-like limb of the shorter bifur- 



tae. 



The specimen of Stat. 274 lias a length of 30111111., but its head is strongly withdrawn 

 and therefore the caruncle could not be recognized.
