of the Gulf of St. Lawrence. 265 



Eupolynoe anticostiensis^ n. sp. 



Dredged rather abundantly in various parts of the Gulf of 

 St. La\VTence in 1873. Distinguished under the naked eye 

 by the somewhat elongated and flattened cylindrical body, 

 covered with curiously mottled brownish scales with a distinct 

 median spot. 



Head with two eyes situated near the posterior border, and 

 two under the outer margin of the somewhat pointed anterior 

 lobes, so that they are not seen from the dorsum. The tentacle 

 has a filiform tip, and the tentacular and dorsal cirri are fur- 

 nished with rather short but very characteristic clavate papillas. 

 The palpi likewise terminate in a filiform tip, and have minute 

 papillae sparsely distributed. The ventral cirri are short, 

 scarcely reaching the base of the bristles, and with a few short 

 clavate papillae. The tips of tlie dorsal cirri also scarcely reach 

 the tips of the bristles. The caudal styles are somewhat 

 short. 



There are fifteen pairs of scales, covering the body completely 

 from head to tail ; they are small in front, and increase in size 

 posteriorly, the last pair being the largest as well as the most 

 ovoid. From the brownish spot in the centre a curved brown- 

 ish band, minutely speckled, proceeds inwards, sweeps round 

 the posterior border, and terminates at the outer edge. This 

 gives the dorsum of the perfect animal the characteristic ap- 

 pearance formerly noted. They are nearly smooth, with the 

 exception of a few short papillee on the surface. 



The dorsal branch of the foot has finely taj^ered and boldly 

 serrated bristles, somewhat like those in Nychia (PI. X. fig. 1). 

 Some shorter forms occur next the body (PI. X. fig. 2). 

 The ventral division has superiorly a group with extremely 

 elongated tips, some of which, however, are minutely forked 

 if careful investigation is made (PI. X. fig. 3). The tips gra- 

 dually diminish in length and increase in stoutness, the bifid 

 end having a broad and rather blunt terminal hook and a well- 

 marked secondary process inferiorly (PI. X. fig. 4). 



There are considerable differences between this and the fir- 

 mer species ; but in the present state of the Annelida complica- 

 tion in names is to be avoided. 



Nemidia (?) canadensis^ n. sp. 



Body somewhat elongated, consisting of about forty-eight 

 segments exclusive of head and tail. The head has four eyes, 

 which hold a somewhat median ]wsition — that is, leave a con- 

 siderable space in front and behind tlu' ])airs. The anterior 

 pair, as usual, are larger. The pal])i are smouth ; tentacle and
