present was var. borealis; thus for instance Mc Intosh's own statement of the occurrence 

 of N. lumbricalis off the Shetlands (9, p. 339), a statement which he does not ref er to in 

 his above-mentioned monograph. Hornell's statement (14, p. 251) of the occurrence 

 of N. lumbricalis off Holy Island, Anglesey (Liverpool district), 29 m., seems to be cor- 

 rect, to judge from his mention of 2 »anteanal segments». In the »First Report on the 

 marine Fauna of the South-west of Ireland» (13, p. 602) N. lumbricalis is mentioned from 

 a depth of about 200—220 m., and it is more probable that the var. borealis of this spe- 

 cies was found than N. maculata. 



Gemmill (20, p. 361) gives Nic. lumbricalis from the west coast of Scotland, 43 m.; 

 he thinks that the species he found is probably the same as the one given by Herdman 

 (11, p. 202) from Lamlash Bay under the name of Clymene borealis. Herdman' s find 

 may be N. maculata Arwedsson, as he also includes N. lumbricalis (though among the 

 Amphictenidae, p. 203), but it is somewhat uncertain whether the species taken by 

 Gemmill at such a depth as 43 m. is N. maculata and not N. lumbricalis var. borealis. 



With regard to Clymene borealis Dalyell Mc Intosh puts this name without 

 hesitation (31, p. 302) as a synonym of N. maculata ; under these circumstances the 

 species ought of course to be called Nicomache borealis (Dalyell). Dalyell's species 

 seems, however, to be so incompletely known that nothing certain can be said on this 

 mat ter.

Of this species, characterized by 22 setigerous segments and 1 achaetous segement, 

 there is a complete specimen present, about 50 X 2 mm., from Brandon Island, Departure 

 Bay on the east coast of Vancouver Island, British Columbia, about 6 m. The specimen 

 has 25 anal cirri, of which nos. 4, 6 and 22 — when the cirrus of the lef t side situated near- 

 est to the ventral line is taken as 1, and the counting continues clockwise — are especially 

 small (ef. Jonhson). The other cirri are fairly equal in size, but the lateral ones are the 

 biggest (ef. Johnson's fig. ). No. 19 is specially big, and nos. 23 and 24 are joined at 

 the base; finaly no. 24 is rather small. The brown colour of the anterior end extends 

 to the 3 rd setigerious segment, but is påle behind the parapodia (ef. figs. 5 and 6 for the 

 design). 



The fully developed points of the anterior capillary setae resemble the correspond- 

 ing ones in, for instance, Petaloproctus tenuis, in other words they possess distinct, strong 

 lateral teeth. The lower, long capillary setae, whose number and distribution (ef. John- 

 son) I have not investigated, are almost quite smooth ; at most exceedingly small 

 lateral teeth, not placed specially close together, are visible. 



Petaloproctus sp.? 



At the same time as the preceding specimen a Petaloproctus spec. was taken that 

 is now unfortunately divided into 3 parts. Assuming that these parts comprise the
